Quick Answer
The D3536 brushless motor is a mid-sized outrunner commonly used in RC aircraft, multirotors, and light industrial applications. Its datasheet typically includes stator dimensions (35mm diameter, 36mm height), KV ratings ranging from 700 to 1450, maximum power around 300-600W, and recommended propeller sizes. Understanding these parameters helps you match the motor to your specific thrust, and efficiency requirements. However, not all datasheets include the same speed level of detail, and some critical values like actual efficiency curves or thermal limits may need verification with the supplier.
Introduction
When you are sourcing a D3536 brushless motor for a new drone design or an RC plane upgrade, the datasheet is your first and most important reference. Yet many procurement engineers and hobbyists find themselves comparing specs that do not align, missing critical parameters, or selecting a motor that underperforms in real flight conditions. The problem is not the motor itself, it is how the datasheet is interpreted. Without a clear understanding of what each specification actually means for your application, you risk choosing a motor that draws too much current, overheats under load, or delivers insufficient thrust. This article walks you through the D3536 brushless motor datasheet, explains what each parameter means for your build, and helps you avoid common selection mistakes.

What the D3536 Model Number Tells You
The naming convention for brushless outrunner motors follows a standard pattern. The first two digits refer to the stator outer diameter in millimeters, and the next two digits refer to the stator height. For the D3536, the stator diameter is 35mm, and the stator height is 36mm. This makes it a medium-sized motor, larger than a 22-series but smaller than a 50-class motor.
Why does this matter? The stator size directly influences the torque the motor can produce. A larger diameter and taller stator generally mean more copper windings and stronger magnetic fields, which translates to higher torque and power handling. In practical terms, the D3536 is suitable for planes weighing 1.5 to 3.5 kg, medium-sized quadcopters, and some light industrial applications like small conveyor drives orbrushless motortest stands.
When you see a datasheet, always verify that the stator dimensions match the model number. Some suppliers may use the outer can dimensions instead, which can be slightly larger. This mismatch can lead to incorrect mounting and performance expectations.
Key Electrical Specifications on the Datasheet
A complete D3536 datasheet should include the following electrical parameters:
KV Rating: RPM per volt with no load. Common values are 700KV, 800KV, 1000KV, 1200KV, and 1450KV.
Resistance (Rm): Internal resistance in milliohms. Lower resistance means higher efficiency and less heat.
No-Load Current (Io): Current drawn at a given voltage with no propeller attached. This helps estimate iron and friction losses.
Maximum Continuous Current (Imax): The current the motor can sustain without overheating. This is often given with a specific cooling condition.
Peak Current (Ipeak): Short-duration current the motor can handle, usually for 10-15 seconds.
Number of Poles: Typically 12N14P or 12N10P for this size. More poles generally mean smoother operation at low RPM.
Not all datasheets list every parameter. When resistance or no-load current is missing, you cannot accurately calculate efficiency or predict heat generation. In such cases, request the full datasheet from the supplier or test the motor under controlled conditions.
Mechanical Dimensions and Mounting Considerations
The D3536 motor has a can diameter of approximately 41-43mm and a total length of 45-55mm, depending on the shaft length and cooling fan design. The shaft diameter is typically 4mm or 5mm, and the shaft length is around 15-20mm.
Mounting holes are usually spaced 16mm and 19mm apart in a cross pattern, compatible with standard firewall mounts and X-mounts. The motor weight ranges from 75g to 110g. Weight matters for applications where every gram affects flight time or payload capacity.
Check the datasheet for the following dimensions:
Can diameter and length
Shaft diameter and exposed length
Mounting hole pattern and bolt size
Overall weight including cables
If you are replacing an existing motor, compare these dimensions carefully. A motor that is 2mm wider may not fit your motor mount or cowling. Similarly, a longer shaft may require spacers or a different propeller adapter.
KV Rating and Its Impact on Performance
KV rating is the most misunderstood specification on a brushless motor datasheet. It is not a measure of power. It tells you how fast the motor tries to spin at a given voltage. A 1000KV motor on a 4S LiPo (14.8V) will try to reach 14,800 RPM under no load. Under load, actual RPM will be lower.
For the D3536 motor, the KV rating determines your propeller size and flight characteristics:
Low KV (700-800): Higher torque, suitable for larger propellers, more thrust at low speed, ideal for slow flyers, trainers, and heavy-lift multirotors.
Medium KV (1000-1200): Balanced performance, works well with 10x5 to 11x7 propellers, good for sport planes and medium-sized quadcopters.
High KV (1400-1450): Higher RPM, smaller propellers, better for fast planes and racing drones, but lower static thrust.
Selecting the wrong KV for your application leads to either inefficient operation or excessive current draw. Always match the KV to your expected voltage and propeller size, not just to a number you saw in a similar build.
Recommended Propeller and ESC Combinations
A reliable D3536 datasheet will include a table of recommended propellers and corresponding current draw. This table is essential for selecting the correctESCand battery.
Typical combinations for a D3536 1000KV motor on 3S to 4S LiPo:
These values are approximate and vary by motor efficiency, air density, and propeller brand. Always leave a 20% safety margin on your ESC rating. If the table shows 40A max, use a 50A ESC. This prevents overheating and ESC failure during extended throttle use.
Maximum Power, Current, and Thermal Limits
The D3536 brushless motor is typically rated for 300W to 600W continuous power, depending on the KV variant and cooling conditions. Peak power can reach 700W for short bursts.
Thermal management is critical. The motor's efficiency determines how much input power becomes heat. At 80% efficiency, 20% of the input power is wasted as heat. For a 500W input, that is 100W of heat that must be dissipated. Without adequate airflow, the motor can reach 80-90°C within minutes, damaging the magnets and winding insulation.
Check the datasheet for:
Maximum continuous power (W)
Maximum continuous current (A)
Recommended cooling conditions (eg, sufficient airflow, forced cooling)
Maximum operating temperature (typically 80-90°C for N35SH magnets)
If the datasheet does not include thermal limits, assume conservative values and test under load. Overheating is one of the most common failure modes inbrushless motorapplications, especially in enclosed or low-ventilation setups.
Common Mistakes When Reading the D3536 Datasheet
Many buyers and builders make the same errors when evaluating a D3536 motor datasheet:
Confusing no-load RPM with loaded RPM: The motor will never reach its KV x voltage RPM under load. Expect a 15-25% drop.
Ignoring the efficiency curve: Some datasheets only list peak efficiency, not efficiency at typical operating points. A motor may be 85% efficient at 50% throttle but only 70% at full throttle.
Using peak current as continuous rating: Peak current is for short bursts only. Running at peak continuously will overheat the motor.
Overlooking the propeller table: Without a recommended propeller list, you are guessing the correct prop size. This can lead to excessive current or poor thrust.
Not verifying mounting dimensions: A 1mm difference in shaft diameter or bolt pattern can make the motor incompatible with your mount.
Avoid these mistakes by cross-referencing the datasheet with your actual operating conditions and testing the motor before full deployment.
How to Compare D3536 Motors from Different Suppliers
When you have multiple D3536 motors to evaluate, use a consistent comparison framework. Create a table with the following columns:
From this comparison, Supplier C offers the lowest resistance and highest power, but at a higher cost. Supplier A provides a balanced option. Supplier B may be suitable for budget builds but has higher losses and lower power.
When comparing, prioritize parameters that affect your specific application. For a high-efficiency long-flight drone, lower resistance and no-load current matter more than peak power. For a short-duration racing application, peak power and weight may be more important.
Questions Buyers Often Ask About the D3536 Brushless Motor
What voltage range is safe for a D3536 motor?
Most D3536 motors are rated for 2S to 4S LiPo batteries, with some high-KV variants supporting up to 5S. Always check the datasheet for the maximum voltage. Exceeding the rated voltage increases RPM beyond safe limits and can cause mechanical failure.
Can I use a D3536 motor on a 6S battery?
Not recommended unless the datasheet explicitly states 6S compatibility. The higher voltage will increase RPM and current beyond the motor's design limits, leading to overheating and potential demagnetization.
What is the difference between a D3536 and a D3548 motor?
The D3548 has a taller stator (48mm vs 36mm), which provides more torque and higher power handling. The D3536 is lighter and more compact, suitable for smaller airframes and lower power applications.
How do I choose the right KV for my RC plane?
For a 1.5-2.5 kg sport plane, 1000KV on 4S with a 10x5 prop is a common starting point. For slow flyers or heavy-lift multirotors, use 700-800KV with larger props. For fast pylon racers, 1400KV with a 9x6 prop works well.
Does the D3536 motor come with a mounting kit?
Many suppliers include an X-mount, propeller adapter, and bullet connectors. Some do not. Verify what is included in the package before ordering, especially if you need specific mounting hardware.
What ESC should I use with a D3536 motor?
Use an ESC rated at least 20% higher than the maximum continuous current listed in the datasheet. For a 40A motor, a 50A ESC is a safe choice. For high-throttle applications like 3D flying, consider a 60A ESC.
Can the D3536 motor be used for a quadcopter?
Yes, but it is larger and heavier than typical quadcopter motors. It is more suitable for heavy-lift or long-range multirotors where payload capacity is prioritized over agility.
How do I calculate flight time with a D3536 motor?
Flight time depends on battery capacity, average current draw, and motor efficiency. For a 4S 5000mAh battery and average draw of 25A, expect around 10-12 minutes of mixed throttle flying. Use an online eCalc tool for more accurate estimates.
What happens if I use a propeller that is too large?
A propeller that is too large will draw excessive current, overheating the motor and ESC. It can also cause mechanical stress on the shaft and mount. Always stay within the recommended propeller range from the datasheet.
Is the D3536 motor suitable for industrial applications?
In some cases, yes. The D3536 can be used for light conveyor drives, small pumps, or test equipment where precise speed control and moderate torque are needed. However, industrial applications often require IP-rated enclosures and higher reliability, so verify with the supplier.
Choosing the Right D3536 Motor for Your Application
Selecting the correct D3536 brushless motor comes down to matching the datasheet specifications with your real operating conditions. Start by defining your voltage, desired thrust, and acceptable current draw. Then compare KV ratings, resistance values, and recommended propeller combinations across suppliers.
Do not rely on a single parameter. A motor with a higher KV may look attractive for speed, but if your application requires low-speed torque, it will disappoint. Similarly, a motor with lower resistance may cost more, but the efficiency gain can pay off in longer flight times or lower operating costs.
If you are unsure about which variant fits your build, send your specifications to the supplier and ask for a recommended configuration. A reputable supplier will provide a matched propeller, ESC, and motor combination based on your weight, voltage, and performance targets.
For buyers evaluating multiple options, request the full datasheet including efficiency curves and thermal data. Compare motors using a consistent table like the one shown earlier. This structured approach reduces the risk of selecting an incompatible or underperforming motor.
When you are ready to move forward, consider requesting a sample or a small batch for testing before committing to a larger order. This allows you to verify real-world performance against the datasheet and confirm that the motor meets your efficiency, heat, and thrust requirements.
