Products for USB Sensing and Control
The DCM4102 is a 24 volt brushless DC motor, generating 16.32 Kg-cm of torque at 260 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 15:1 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 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.
The following brushless controllers can be used to drive this motor:

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. For more guidance on building a transmission system, visit our Rotary Motion Guide. Here is a list of our 8mm bore pulleys and sprockets:
