Single phase motor for air compressor choosing
The basic content required for the selection of an air compressor motor includes: the type of load drive, rated power, rated voltage, rated speed and other conditions.
1. Air compressor DC motor:
For production machinery that requires large starting torque and soft mechanical characteristics, series excitation or composite excitation DC motors are used, which are suitable for trams, electric locomotives, heavy cranes, etc.
2. Air compressor asynchronous motor:
For continuous operation production machinery without special requirements for load stability, alignment and braking, ordinary squirrel cage asynchronous motors should be preferred, which are widely used in machinery, water pumps, fans, etc. Starting and braking are frequent, and production machines that require large starting and braking torque should use winding asynchronous motors, such as bridge cranes, mine hoists, air compressors, and irreversible rolling mills.
3. Synchronous motor for air compressor:
If there is no speed regulation requirement, the speed needs to be constant or the power factor needs to be improved, a synchronous motor should be used, which is suitable for medium and large capacity water pumps, air compressors, hoists, mills, etc. For production machinery with a speed control range of 1:3 or more and continuous, stable and stable speed control, a separately excited DC motor or a squirrel cage asynchronous motor or a frequency conversion synchronous motor should be used. It is suitable for large precision machine tools, double planers, and rolling mills. , Hoist, etc.
