36mm Brushless DC Motor – 70mm Length, High Efficiency, Long Life
The M36-70-BLDC series is a 36mm diameter brushless DC motor with an extended 70mm body length. This powerful motor platform is designed for applications requiring substantial torque output without transitioning to larger, more expensive 42mm or 56mm frames. The combination of 36mm diameter and 70mm length provides an excellent power-to-size ratio for industrial automation, robotics, medical equipment, and consumer appliances.
The M36-70 delivers rated torque from 0.25 to 0.50 Nm with peak torque up to 1.2 Nm, depending on winding selection. No-load speeds range from 1,500 to 8,000 RPM, allowing designers to optimize for either high-speed or high-torque applications. The extended 70mm body accommodates a longer stator with more copper windings and stronger rare-earth magnets, resulting in significantly higher torque output compared to shorter 36mm motors (such as 36×50mm versions). The brushless design provides high efficiency (up to 88%), reducing heat generation and improving energy economy.
Unlike traditional metal brush DC motors that require periodic brush replacement and suffer from electrical arcing, the brushless design eliminates mechanical commutation entirely. Typical operational life reaches 20,000+ hours—four times longer than equivalent brushed motors. The absence of brushes also eliminates electrical arcing, reducing EMI and making the motor suitable for sensitive medical and electronic environments. Low cogging torque design ensures smooth rotation even at very low speeds, critical for precision positioning applications.
Three integrated hall effect sensors provide commutation feedback for electronic speed controllers (ESC) and enable precise speed control, direction changes, and smooth starting from zero speed. The hall sensors allow the motor to start reliably under load and maintain stable operation across a wide speed range. For closed-loop speed or position control, an optional magnetic or optical encoder (up to 1,024 PPR) can be added to the motor rear shaft.
The 70mm body length provides substantial surface area for passive heat dissipation. Ball bearings (double shielded) on both ends ensure low friction and long service life even under continuous duty. Dynamic balancing of the rotor assembly minimizes vibration, important for precision applications such as CNC axes and surgical robots. The housing can be specified with IP54 protection (dust-protected and water-resistant) or IP65 (wash-down capable) for demanding environments. Insulation is Class F (155°C) as standard, with Class H (180°C) available for high-temperature applications.
OEM customers can specify winding voltage and speed/torque characteristics, shaft diameter (6mm, 8mm, or 10mm), shaft length, and end configurations including flat, keyway, D-cut, or spline. Gearbox attachments (planetary or spur) with reduction ratios from 3:1 to 100:1 are available for torque multiplication. Custom lead wire length and connector terminations (Molex, JST, AMP, Deutsch, or custom) are supported. Encoder integration, electromagnetic brake options, and IP65 sealing are available for volume orders.
Each M36-70-BLDC motor undergoes 100% final inspection including no-load speed, no-load current, hall sensor functionality, insulation resistance, dielectric strength, and vibration testing. Production follows ISO 9001:2015 quality management processes. RoHS and REACH compliance documentation is available. Sample motors with matched electronic speed controllers are available for engineering evaluation.

Φ40×70mm Metal Brush Commutation Motor for Power Tools & Industrial Drives
The M40-70 series is a 40mm diameter metal brush DC motor with an extended 70mm body length, representing a significant step up in power from smaller 32mm and 36mm frame motors. This motor platform is designed for applications requiring substantial torque output without transitioning to larger, more expensive 56mm or 63mm frames. The combination of 40mm diameter and 70mm length provides an excellent power-to-size ratio for power tools, industrial equipment, medical devices, and household appliances.
The M40-70 delivers stall torque up to 600 mNm, approximately 70% higher than a typical 32×60mm motor and 40% higher than a 36×60mm motor. No-load speeds range from 1,200 to 8,000 RPM depending on winding selection, allowing designers to optimize for either high-speed or high-torque applications. The metal brush commutation system uses large-format carbon-copper brushes that provide reliable electrical contact under high current loads. Starting torque is exceptionally high, enabling direct drive of mechanisms that would require gearing with smaller motors.
The extended 70mm body length provides substantial surface area for passive heat dissipation, essential for power tools and industrial applications where continuous operation is common. Ball bearings are available as standard on both ends (or sintered bronze for cost-sensitive applications), providing low friction, high radial load capacity, and extended service life. Ventilation slots can be added to the housing for forced air cooling. Insulation is Class B (130°C) as standard, with Class F (155°C) available for high-temperature environments.
The M40-70 features a precision-drawn or machined steel housing with integrated mounting bosses. The commutator is precision diamond-turned for smooth brush interaction, minimizing sparking and extending brush life beyond 3,000 hours under typical loads. Dynamic balancing of the rotor assembly reduces vibration and noise, particularly important for handheld power tools and medical devices. Terminal connections are reinforced to withstand vibration and repeated plugging cycles.
OEM customers can specify shaft diameter (8mm, 10mm, or 12mm), shaft length, and end configurations including flat, keyway, D-cut, knurling, or gear cutting. Gearbox attachments (planetary or spur) with reduction ratios from 3:1 to 100:1 are available for torque multiplication. For speed feedback, magnetic or optical encoders can be integrated. Custom lead wire length, connector terminations (Molex, JST, AMP, Deutsch), and EMI suppression components (capacitors, varistors) are supported for volume orders.
Each M40-70 motor undergoes 100% final inspection including no-load speed, no-load current, insulation resistance, dielectric strength, mechanical runout, and vibration testing. Production follows ISO 9001:2015 quality management processes. RoHS and REACH compliance documentation is available. Custom winding configurations and performance curves can be developed for OEM volume orders. Sample motors are available for engineering evaluation.
