The DCM4104 is a 24 volt brushless DC motor, generating 50 Kg-cm of torque at 70 RPM.
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 56:1 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. Have a look at the Connection & Compatibility tab for a list of compatible Phidget controllers.
This motor comes with a 5-Pin molex connector soldered to the hall effect wires, and ferrules crimped onto the motor wires so it can quickly and easily be connected to the Brushless DC Motor Phidget as shown in the functional picture.
This motor must be controlled by a brushless DC motor controller. 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.

If you need to connect the main shaft of this motor to the shaft of another device, you can use a shaft coupler:

|TRM4313_0||$3.00||8 mm||Aluminum||35.7 kg·cm||12000 RPM||—|
|TRM4334_0||$3.35||8 mm||Aluminium||10 kg·cm||8000 RPM||110 N·m/rad|
If you're using this motor to drive a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the motor. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance.
