In the selection of motor products, many equipment manufacturers often worry when choosing supporting equipment, because how to choose a suitable power of three-phase asynchronous motor, the following and Senli motor small series Let's take a quick look.

       In the choice of power, if it is too large, it will cause unnecessary waste of investment, because the relative power is more expensive in price, and the loss generated when it is put into operation in the later period will be greater; However, if the selection is small, it will be difficult to start, and when the working current exceeds the rated current during operation, it is easy to cause the motor winding to overheat and burn. inThree-phase asynchronous motorWhen choosing power use, it is necessary to choose according to the nature of different loads.

       Some short-term operation of the motor, which can be allowed to operate at a larger proportion, should be determined by whether the motor torque can meet the load torque requirements. When choosing the motor capacity, it is also necessary to consider the size of the power supply transformer capacity, in general, the largest direct start1The capacity of the asynchronous motor should not exceed the capacity of the power supply transformer1/3.
