DCM4108_0 57DMWH75 NEMA23 Brushless Motor with 15:1 Gearbox
This 4-pole BLDC gear motor can output 37.7kg-cm of torque at speeds of up to 250 RPM. The shaft has a 4mm keyway for better coupling.
The DCM4108 is a 24 volt brushless DC motor, generating 37 Kg-cm of torque at 250 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 15:1 planetary gearbox on this motor results in higher torque at the cost of speed.
The planetary gearbox on this motor is more sophisticated than a typical spur gearbox and will provide greater efficiency, higher torque, and quieter motor operation.
Connection
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.
