Geared Brushless DC Motor

A gearbox designed specifically for our smallest brushless DC motor provides a very compact package that produces a rated torque of 175 oz-in and a peak torque of 500 oz-in.

Gears are hobbed to AGMA 7 quality. Pinions and gear teeth are case hardened for wear resistance and ground steel shafts rotate in sintered bearings. The output shaft is supported by ball bearings. Both motor and gearhead are designed for outstanding service.

Gearboxes are available in a wide variety of sizes and ratios for all Hurst brushless DC motors. Consult your sales person for more information.

This size motor is also available with an encoder. BLDC 4817-004
