    Air Compressor Motor Price List

    Air compressor motors are electrical devices that convert electrical current into mechanical rotational energy, or torque, by using alternating current from an electrical power grid or electrical generator. General-purpose air compressor motors, also known as induction motors, are electric motors that use a rotating magnetic field to generate torque for powering conveyors and machine tools.

    Air Compressor Troubleshooting

    The air compressor is a compressed gas equipment that is applied for every process of industrial production. As an important industrial equipment, the air compressor provides pneumatic power sources, which is a core device of the pneumatic system. It changes mechanical energy of dynamic into gas pressure energy, which is an air pressure generating device of compressed air. However, if some problems occur in the air compressor, how should we discover and resolute?

    Direct Drive Air Compressor vs. Belt Driven Air Compressor

    As an important form of energy generation, air compressors are widely used in various industrial fields, including mechanical, metallurgy, Electronic power, medicine, packaging, chemicals, food, textile, transportation and so on.
    Direct drive of air compressor refers to the motor main shaft to drive the rotor by the coupling and the gearbox speed, which is not actually a direct drive in practical sense.
    Direct drive in the true sense means that the motor is directly connected with the rotor (Coaxial), which has the same speed. This situation is obviously very rare. Therefore, it is a wrong view that there is no energy loss in direct drive.
    Another drive way is belt driven, which allows the rotating speed of the rotor to be changed by pulleys of different diameters.

    How Does VFD Work on Air Compressor?

    It is found that the speed of air compressor motor is proportional to the actual consumed power of the air compressor. Therefore, it is necessary to reduce the motor speed in order to reduce the actual consumption of the air compressor. The use of VFD in air compressor system can realize the real time control of motor speed (output power) without changing the air compressor motor torque through the accurate coordination of electrical control and frequency control in the air compressor system. To change the compressor speed to respond to the system pressure changes and to maintain stable system pressure can realize the output of high quality air pressure according to demand.

    Single Stage vs. Two Stage Compression of Piston Air Compressor

    In the actual use of some low pressure and medium pressure piston type portable air compressor, the two stage compression is often used. The intermediate cooler is set. After the cooling of high temperature air discharged from single stage compression, it is then inhaled into two stage cylinder for two stage compression so as to reach the required pressure. Adopt two stage compression, because if use single stage compression to obtain higher air pressure, the pressure ratio (the ratio of the exhaust pressure and suction pressure) is too large, so that the compression process.
