The DCM4105 is a 24 volt brushless DC motor, generating 190 Kg-cm of torque at 38 RPM. The shaft is equipped with a 4mm key to improve coupling.

Brushless DC motors provide convenient position and velocity control through the use of their built in hall-effect sensor. They run quieter and last longer than their brushed counterparts. The 106:1 planetary gearbox on this motor results in higher torque at the cost of speed.

This motor must be controlled by a brushless DC motor controller that has the capability to both send control signals to the three motor wires, and also read the hall-effect feedback from the other five wires.

This diagram shows how to connect the motor wires to the controller.

Note: Because of the way this motor is built, you'll need to set negative P, I and D values when using the MotorPositionController object.

Note: Make sure to unplug the power cord from the motor controller before switching wires around.
