1. The economic choice; the general import is much more expensive than the domestic, Hong Kong, Macao and Taiwan is more expensive than the mainland. Specific circumstances depend on the specific needs of the enterprise.) Whether imported or domestic manufacturers have their own naming specifications, now in the reducer market. Therefore, it is best to find a sample of the deceleration motor and choose according to the sample.

2.type selection; decelerating motor has cage type and winding type two. But the starting performance is poor. The cage type decelerating motor has the advantages of simple structure, easy maintenance and low price. Generally no load or light load starting machine can be selected.

The starting current is small, and the starting torque of the wire wound decelerating motor is large. But the structure is complex, starting and maintenance is more troublesome, only used in places where large starting torque is needed, such as lifting equipment, in addition can also be used in mechanical equipment requiring appropriate speed regulation.

3.Selection of power; Selection of the power of the deceleration motor is determined by the production machinery, that is to say, the power of the distribution motor required by the deceleration motor determined by the power required by the load is as follows: Motor power = torque 9550, motor power input revolutions, ratio of speed to use coefficient.

4.Selection of rotational speed; The speed of deceleration motor is close to synchronous speed, and the magnetic field speed is divided by the number of magnetic poles P between the two gears is not.
