775 DC motor Electric drill motor high torque 12V 12000RPM. Ball bearing with cooling fan. This is the front end of the motor ball bearing, copper sets of back-end, 5 groups winding, at a voltage of 12V, large torque, low noise. Motor bearings are mechanical devices designed to support the rotational movement of shafts or axles while minimizing friction. They consist of two concentric rings—a stationary outer ring and a rotating inner ring. A DC motor is any motor within a class of electrical machines whereby direct current electrical power is converted into mechanical power. Most often, this type of motor relies on forces that magnetic fields produce.
