DFRobot M0601 Direct-Drive Hub Motor with Integrated FOC Servo for AGVs

The M0601 is a 102mm drive wheel with the brushless motor, FOC servo driver and encoder built into the hub, made for AGVs, AMRs and service robots. Because the drive electronics sit inside the wheel, a chassis needs only power and an RS485 bus to each wheel, with no external motor controllers or gearboxes.

Key features

• Direct drive: the motor turns the wheel without a gearbox, for smooth torque delivery and lower mechanical losses

• FOC control with a 4096-count encoder for closed-loop torque, speed and position control

• RS485 interface with real-time position, speed and current monitoring

• IP54 protection and running noise of 50dB or less

• Left and right versions to suit each side of a differential-drive chassis
