Three-phase asynchronous motors are widely used in transmission equipment in production and life. Three-phase asynchronous motors generally have relatively large power, such as the power range that can be selected from 0.12KW to more than 300KW.Taking into account the matching performance of the motor and the reducer and the transmission torque should be sufficient for the equipment load. If the power of the three-phase asynchronous motor is large, the model of the reducer used also needs to be larger. For example, the requirements of the transmission equipment in terms of load, working conditions, etc. are not very large or the accuracy requirements are not very strict. The three-phase asynchronous motor 15KW can be equipped with RV series worm Brush DC Gear Motors Suppliers. Conversely, if working conditions such as mining machinery and large mixers are more complicated, and the transmission equipment is heavily loaded, considering the service life and better performance, a hard-tooth surface series reducer should be selected. How to choose which type of reducer for a three-phase asynchronous motor?For example, if the motor power is 15KW, the motor frame size is 160M. If there are no too many requirements for the reducer, the lower cost is the RV reducer, then the 15KW three-phase asynchronous motor needs to use the RV reducer 150 model. The smallest model of the RV series reducer is 025, and the largest model is 150. It can be seen that a motor with a high power such as 15KW needs to use the largest reducer model. However, if you want the equipment to be longer and more durable, with more sufficient torque, it would be better to have a three-phase asynchronous motor 15KW with a hardened gear reducer.However, even if the reducer is replaced with a hardened gear reducer, there are prerequisites, and not any type of reducer can meet the requirements. There are four series of hard tooth surface reducer: R series, F series, S series, K series, no matter which series of hard tooth surface reducer is used, if the motor power is 15KW, use the safety factor (FB) as the reference, Only those with FB greater than 1 are recommended. According to the Yongkun brand hard-tooth surface reducer selection manual, R series reducer needs to be greater than or equal to RC137 model, K series needs to be greater than or equal to KC97 model, F series needs to be greater than or equal to FC77 model, and S series needs to be greater than SC97 model. In summary, the greater the power of the three-phase asynchronous motor, the larger the reducer model that needs to be used. As for the specific model of the reducer, it needs to be determined according to the manufacturer's selection manual.
