pm spur gear motor supplier refers to the gearbox with small volume and capacity, and the output power is generally below hundreds of watts, and the gearbox with special requirements for use, performance and environmental conditions, the full name of micro reduction gearbox, referred to as pm spur gear motor supplier. It is often used in control systems to realize the detection, calculation, amplification, execution or conversion of electromechanical signals or energy, or to drive mechanical loads, and can also be used as AC and DC power supplies of equipment. So, this pm spur gear motor supplier if the volume is the same, their power size mainly depends on what?

A. Design of motor shape, layout of heat dissipation hole, etc.

B. The thickness of the coil, the thicker the wire diameter, the fewer turns wound, the number of motor revolutions, but the torque is not large. However, the smaller the line diameter, the more turns wound, the motor speed is low, but the torque is large. Hand wound speed, expensive. Machines do the opposite.

C. The selection of magnets, strong magnets, large torque, vice versa small.

D. bearing selection, ball bearing is the necessary parts of the speed motor, the general motor is used with oil bearing.

E. The selection of data indirectly affects the service life.

F. The use of brushes, you talk about the use of copper brush and carbon brush functions and differences are:

1. Copper brush, low cost, small power function target is not, and short life.

2. Carbon brush, cost, large power, revolution and function and life are very good, speed motor is carbon brush

J. Battery selection.
