Single-phase asynchronous motor uses single-phase AC power supply, so it is more convenient to use, so it is commonly used in household appliances and small power machinery with little power, then let's understand some characteristics of the next single-phase asynchronous motor.

       A phase asynchronous motor is a rotating motor powered by a single phase AC power source ,The stator winding is single phase. When single-phase AC power is connected ,It generates an alternating pulsating magnetic field in the constant rotor air gap ,Therefore, single-phase asynchronous motors cannot start themselves.

       In AC motor, when the stator winding passes through AC current, the armature magnetomotive force is established, which has great influence on the energy conversion and operation performance of the motor. Therefore, single-phase AC winding passes into single-phase AC to generate pulse magnetomotive force. The magnetomotive force can be decomposed into two rotating magnetomotive forces with equal amplitude and opposite speed, so as to establish the vertical and reverse magnetic field sums in the air gap.

       Single-phase asynchronous motor power is small, mainly made of small motor. Before the motor is installed to the supporting machinery, it is necessary to carefully check whether the foot part of the motor has cracks and affects the mechanical strength and other problems, once the problem is found, it is prohibited to install and use.
