If I have an air compessor that uses an 11 horse power gas engine.
How do I know what size electric motor, and what RPM will do the same job?

The correct size of an air compressor motor is determined by calculating the required horsepower (HP) and matching it with the motor's rated HP. To determine the required HP, you will need to know the air demand of your tools or equipment, the compressor's duty cycle, and the compressor's efficiency. It's important to choose a motor with a slightly higher HP rating to ensure it can handle any potential increases in air demand.
The recommended RPM for an air compressor motor depends on the type of compressor you are using. For a reciprocating air compressor, the recommended RPM range is typically between 900-1200 RPM. For a rotary screw compressor, the recommended RPM range is typically between 1750-3500 RPM.
Yes, you can use a single-phase motor for your air compressor. However, single-phase motors are not as efficient as three-phase motors and may struggle to start under heavy loads. If possible, it is recommended to use a three-phase motor for larger air compressors.
If your air compressor motor is overheating, you may notice a burning smell or hear unusual noises coming from the motor. The motor may also shut off on its own or trip the circuit breaker. You can also check the motor's temperature by feeling the exterior. If it is too hot to touch, the motor is likely overheating.
Yes, it is possible to change the RPM of an air compressor motor, but it is not recommended. Changing the RPM can affect the motor's efficiency and may lead to overheating or premature failure. It is best to choose a motor with the correct RPM for your specific compressor needs.
