With the development of electro-technology and the application of various motors, the production of motor products presents various complex forms and various types. Among them, the PV70W20-39PW motor is a relatively common motor type. This article will briefly introduce the application field and working principle of the PV70W20-39PW motor.

The PV70W20-39PW motor is mainly used in the driving of industrial machinery and equipment. It has the characteristics of being reliable in operation, low noise, small size, light weight, high power, good safety performance and strong overload capacity. The full load speed is 220rev / min, the brake torque is 7.5Nm, the allowable power factor is 0.8 and the starting current is 1.2 times of the rated current. The rated voltage of the motor is 220V, the rated power is 70W, the poles are 4 poles, and the rotor type is two-pole single-phase.

The working principle of the PV70W20-39PW motor is that when the motor is at rest, the electric energy is firstly converted into the magnetic field energy, and then the drive shaft is driven to rotate due to the interaction between the magnetism of the electric pole and the electromagnetic force generated by the stator winding. During the rotation of the drive shaft, the direction of the current in the stator winding changes periodically according to the principle of alternating current, which changes the direction of the magnetic field. Under the action of the electromagnetic torque, the rotating rotor keeps its original speed and runs continuously.

Due to its wide range of application fields and stable working performance, the PV70W20-39PW motor is widely used in the motor system of air compressors, fans, pumps, compressors and other industrial general machinery and equipment. In addition, this motor is also used in household appliances, medical equipment, cleaning equipment, and other automated office or factory equipment. It has become an indispensable product in the automation and intelligent equipment industry.

In summary, the PV70W20-39PW motor is a relatively common motor type, which is mainly used in the driving of industrial machinery and equipment. Its working principle is based on the electromagnetism law, which drives the drive shaft to rotate due to the interaction between the magnetism of the electric pole and the electromagnetic force generated by the stator winding, and then drives the corresponding machinery and equipment to run. With the development of technology, this motor has been widely used in household appliances, medical equipment, cleaning equipment and other automated office or factory equipment.
