The variety and operation of permanent magnet motor

According to the characteristics of the starting and running method of the motor, the permanent magnet motor usually divides the single-phase asynchronous motor into five kinds: single-phase resistance starting asynchronous motor, single-phase capacitor starting asynchronous motor, single-phase capacitor running asynchronous motor, single-phase capacitor starting and running asynchronous motor and single-phase cap pole asynchronous motor. Explosion-proof motor A type of motor that can be used in inflammable and explosive places and does not produce sparks during operation. Explosion-proof motor is mainly used in coal mine, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, urban gas, transportation, grain and oil processing, paper making, medicine and other sectors.

Operation of permanent magnet motor: the first kind, in the starting loop is not connected with the centrifugal switch, starting winding and capacitor not only play a role when starting, running also play a role, so it may improve the power factor and effectiveness of permanent magnet motor, so the operation function of this motor is better than that of capacitor starting motor.

Capacitor running motor starting winding series capacitor capacity, it is important to judge according to the operation function request, than according to the motor can request and judge the capacitance is smaller, therefore, the motor can not be as good as the capacitor starting motor. Permanent magnet motor is mainly used in coal mine, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, urban gas, transportation, grain and oil processing, paper making, medicine and other sectors. As the main power equipment, explosion-proof permanent magnet synchronous motor is usually used to drive pump, fan, compressor and other transmission machinery.

Capacitor running motor do not start switch, so the structure is relatively simple, the price is relatively cheap, important used in electric fans, air conditioning fan motor, washing machine and other motors.

Second, the centrifugal switch is connected in the starting loop. This connection method is used individually in air compressor, cutting machine, woodworking machine and other places where the load is large and not firm. Explosion-proof motor A type of motor that can be used in inflammable and explosive places and does not produce sparks during operation. Explosion-proof motor is mainly used in coal mine, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, urban gas, transportation, grain and oil processing, paper making, medicine and other sectors.
