Our first phase of the customer's answer to the problems encountered when the motor is used or replaced, we should pay attention to many problems when purchasing the motor, and will often encounter some failures after the choice, which is inevitable, so today's three-phase asynchronous motor manufacturer Senli Motor will take you together with a simple understanding of the next.

       I. AboutThree-phase asynchronous motorCause of slow speed when starting

       If the speed is only slow when starting, it is normal after starting. It may be that the starting capacitance does not match, or that the motor is designed this way(By site design)It may also be that the starting time is too long caused by factors such as excessive load resistance.

       If the speed is still slow after starting, it may be that the problem may be insufficient voltage, capacitor mismatch, rotation resistance, etc.

       Two.60HZMotor on50HZUse on the power supply, need to pay attention to what?

       This is because the current frequency of the motor is lower than the design frequency, so that the no-load back electromotive force generated in its rotation is reduced, the no-load current is increased, causing damage to the motor, so the no-load voltage is required to reduce.

       In the variable frequency speed regulation technology, the frequency of the motor and the stator voltage are changed simultaneously. Even if the frequency drops, the voltage should also drop at the same time, the motor will not overcurrent, and the ideal operation effect will be obtained.
