The compressor is a heavy load for the engine: high starting torque and continuous operation. Let's look at how to choose a motor for a compressor.
Key requirements
- Sufficient powerwith a reserve for starting load.
- High starting torque - the compressor starts hard.
- Continuous mode S1 - work without stopping.
- Good cooling - the engine heats up under load.
Features
| Compressor type | Drive feature |
|---|---|
| Piston | Pulsating load, high starting torque |
| Screw | Smooth load, often with frequency drive |
Reciprocating compressors create a pulsating load and require a motor with good starting torque. For screw motors, frequency regulation is often used.
Protection and reliability
For compressor motors, overload protection and good cooling are important - overheating is the main reason for their failure. When rewinding, class F or H insulation is used. If the compressor motor often gets hot, check the load and cooling during diagnosis.
