Brief Introduction

Synchronous motor 3 phase for air compressors play an important role in industry, mainly used to drive air compressors. Here are some key points about this motor:

Main features

Constant speed: No matter how the load changes, the speed always keeps pace with the power frequency.

High efficiency: High efficiency at or near full load.

Power factor adjustable: The power factor can be adjusted by adjusting the excitation current, which helps to improve the power factor of the power system.

Start-up stability: By using a frequency converter or other start-up method, a smooth start-up can be achieved and the impact on the grid can be reduced.

Since synchronous motors need to reach synchronous speed to operate properly, starting is a key issue. Common boot methods include:

Frequency conversion start: Use the frequency converter to control the motor start, gradually increase the frequency and voltage, smooth start and achieve synchronous speed.

Induction start: The rotor is installed with a winding, which is started asynchronously by starting the resistance, and then switched to synchronous operation.

Direct start: Suitable for small power motor, direct start through the power supply, but has a large impact on the power grid.
