The 57DMWH75 NEMA23 Brushless Motor w/ 15:1 Gearbox is a 24 volt brushless DC motor, generating 37 kg-cm of torque at 250 RPM. The shaft is equipped with a 4 mm key to improve coupling.
The Brushless DC motor provides convenient position and velocity control through the use of its 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.
It 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. It is controlled by a brushless DC motor controller that can send control signals to the three motor wires.
