1. Type selection
There are two kinds of gear reducer motors: cage type and wire wound type. The cage type reducer motor has the advantages of simple structure, easy maintenance and low cost, but its starting performance is poor, so it can be used for no-load or light-load starting production machinery. Such as lifting equipment, in addition, it can also be used for mechanical equipment requiring proper speed regulation. The selection of general purpose special reducer includes steps such as putting forward the original premise, selecting the type and determining the specifications. By comparison, the type selection is relatively simple, and the correct premise to provide decelerator working conditions, grasp the characteristics of the design, manufacture and use of the reducer is the general reducer accurate and fair choice of specifications of the hub. The selection of specifications should be satisfied with the premise of strength, heat balance, radial load and shaft extension.

2. Power selection
The power selection of gear reducer motor is determined by the production machinery, that is, by the power required by the load. The distribution power required by the deceleration motor is as follows: motor power = torque
3, The choice of speed.
The speed of the gear reducer motor is close to the synchronous speed, and the magnetic field speed is divided by the magnetic pole logarithm P. There is no speed between the two gears. The principle of selecting the speed of the deceleration motor is to make it as close as possible to the speed of the production machinery in order to simplify the rotating device.
4. Speed ratio choice
Choose as close as possible to the ideal deceleration ratio: deceleration ratio = servo motor speed / reducer output shaft speed; torque calculation: for the life of special-shaped reducer, torque calculation is very important, and pay attention to the maximum acceleration torque (TP), whether it exceeds the maximum load torque of the reducer.
