maxon high-torque brushless DC motors

The recently released 90 mm diameter brushless DC ventilated motors from maxon give power level increases from 160 to 600 W within the same diameter. Two length options of 27.4 and 39.9 mm are selectable with two air-cooling options. Four winding options are available for DC voltages varying from 12 to 60 VDC. Continuous torque capability is up to 1610 mNm from the motor alone; when combined with planetary, worm and helical gearhead options, repeated peak torque levels of 650 Nm have been achieved.

High ratios and 25600qc integrated internal encoders make them useful devices for rotary joint applications such as robotics and industrial machinery actuators. The company can also manufacture custom versions with specific cable looms and rear shafts for mounting loads on both sides of the motor. The combination of the flat motors with high stiffness, low profile, zero backlash and trochoidal-style gearheads also makes the complete drive suitable for wheel drive applications such as autonomous ground vehicles and warehouse logistic machinery.
