What kind of reducer is suitable for 15kw three-phase asynchronous motor?

What kind of reducer is suitable for 15kw three-phase asynchronous motor?
Three phase asynchronous motor is widely used in the production and life of the transmission equipment. Generally, the power of three-phase asynchronous motor is relatively large, such as the optional power range of 0.12kw to more than 300 kW.
In consideration of the matching performance of the motor and the reducer and the transmission torque, it should be sufficient for the equipment load. If the power of three-phase asynchronous motor is large, the reducer model used also needs to be larger. For example, the requirements of the transmission equipment in terms of load, working condition and other aspects are not very large or the requirements of accuracy are not very strict. The three-phase asynchronous motor 15kw can be equipped with RV series worm gear reducer. On the contrary, if the working conditions such as mining machinery and large mixer are complex and the load of transmission equipment is large, considering the service life and better performance, the reducer with hard tooth surface series is selected.

How to choose three-phase asynchronous motor with what type of reducer? For example, if the motor power is 15kw, the base number of the motor is 160m. If there are not too many requirements for the reducer and the RV Reducer is the one with low cost, then the RV Reducer 150 model is needed for the 15kw three-phase asynchronous motor.
RV series reducer has a minimum model of 025 and a maximum model of 150. It can be seen that 15kw high-power motor needs the largest reducer model. However, if you want the equipment to be longer and more durable, and have more torque, it is better to have 15kw three-phase asynchronous motor with hard tooth reducer.
However, even if the reducer is replaced by a hard tooth reducer, there are preconditions, not any type of reducer can meet the requirements. There are four series of hard gear reducers: R series, F series, s series and K series. No matter which series of hard gear reducers are used, if the motor power is 15kw, the safety factor (FB) is used as the reference and FB is greater than 1, it is recommended to select. According to the selection manual of Yongkun brand hard tooth reducer, R series reducer needs to be greater than or equal to rc137 model, K series reducer needs to be greater than or equal to kc97 model, F series reducer needs to be greater than or equal to fc77 model, and S series reducer needs to be greater than sc97 model.
In summary, the larger the power of three-phase asynchronous motor, the larger the reducer model needed. As for the specific model of reducer, it needs to be determined according to the manufacturer's selection manual.
