0.25N.m 12 Volt 4000RPM High Speed DC Motor High Torque

4000RPM High Speed Brushless DC Motor , 12 Volt DC Motor High Torque

A motor converts supplied electrical energy into mechanical energy. Various types of motors are in common use. Among these, brushless DC motors (BLDC) feature high efficiency and excellent controllability, and are widely used in many applications. The BLDC motor has power-saving advantages relative to other motor types.

Ideal Applications for BLDC Motors

We can expect to see BLDC motors used in a wider range of applications in the future. For example, they will probably be widely used to drive service robots—small robots that deliver services in fields other than manufacturing. One might think that stepper motors would be more suitable in this type of application, where pulses could be used to precisely control positioning. But BLDC motors are better suited to controlling the force. And with a stepper motor, holding the position of a structure such as a robot arm would require a relatively large and continuous current. With a BLDC motor, all that would be required is a current proportionate to the external force—allowing for more power-efficient control. BLDC motors may also be replacing simple brushed dc motors in golf carts and mobility carts. In addition to their better efficiency, BLDC motors can also deliver more precise control—which in turn can further extend battery life.
