The M36-70-BLDC-Pro series represents a significant advancement in 36mm brushless DC motor technology, combining a 36mm diameter frame with an extended 70mm body length to deliver superior torque output for demanding applications. This motor platform has been specifically engineered to provide higher continuous torque capability than shorter 36mm motors, making it suitable for applications requiring sustained power delivery without increasing motor diameter. The Pro series is ideal for system designers who need reliable, high-performance actuation in robotics, medical equipment, industrial automation, and advanced consumer appliances.
The M36-70-BLDC-Pro delivers rated torque from 0.25 to 0.50 Nm with peak torque reaching 1.2 Nm, offering substantial power reserve for dynamic operating conditions. No-load speeds are available from 1,500 to 8,000 RPM, providing flexibility to match application requirements ranging from high-speed operation to high-torque, low-speed actuation. The motor achieves peak efficiency of 88%, resulting in lower operating temperatures and reduced energy consumption—a critical advantage in battery-powered and thermally constrained systems.
The brushless architecture eliminates the mechanical brushes found in conventional DC motors, removing the primary wear component and significantly extending operational life. With a rated lifetime of 20,000+ hours under typical operating conditions, this motor offers four to five times the service life of equivalent brushed motors. The absence of brush arcing also reduces electromagnetic interference (EMI), enabling reliable integration with sensitive electronic systems in medical and laboratory environments. The motor’s low cogging torque design ensures smooth rotation at all speeds, delivering consistent performance for precision positioning tasks.
Three integrated Hall-effect sensors provide commutation feedback to the electronic speed controller, enabling smooth startup, accurate speed regulation, and instantaneous direction changes. The sensor feedback ensures reliable starting under load conditions and stable performance across the entire operating speed range. For applications requiring closed-loop speed or position control, an optional magnetic or optical encoder with resolution up to 2,048 pulses per revolution (PPR) can be integrated on the rear shaft extension.
The extended 70mm body provides substantial surface area for efficient heat dissipation, supporting continuous-duty operation even at elevated ambient temperatures. Double-shielded ball bearings at both motor ends ensure low rotational friction and long service life under radial and axial loads. The motor’s dynamic balancing process minimizes vibration, making it suitable for precision optics and imaging applications where stability is critical. For challenging environmental conditions, the motor can be supplied with IP54 (dust-protected and splash-resistant) or IP65 (dust-tight and wash-down capable) protection ratings. The standard insulation is Class F (155°C), with a Class H (180°C) upgrade available for high-temperature industrial applications.
The M36-70-BLDC-Pro series offers comprehensive customization options to support OEM integration. Customers can specify winding configurations to achieve target speed and torque characteristics, select shaft diameters of 6mm, 8mm, or 10mm with associated lengths, and define shaft end geometries including flat, keyway, D-cut, or spline. Planetary or spur gearboxes with reduction ratios from 3:1 to 100:1 are available for applications requiring torque multiplication. Additional options include encoder integration, electromagnetic holding brakes, custom lead wire lengths, and specialized connector terminations (Molex, JST, AMP, Deutsch, or custom designs). IP65-rated sealing and high-temperature insulation upgrades are also supported for volume orders.
Quality assurance is a cornerstone of the M36-70-BLDC-Pro series. Every motor undergoes 100% final testing to verify no-load speed, no-load current, Hall sensor functionality, insulation resistance, dielectric strength, and vibration characteristics. The production process is certified to ISO 9001:2015 quality management standards, and full RoHS and REACH compliance documentation is available for all materials and components. Engineering samples with matched electronic speed controllers are offered for application evaluation and system integration testing.
