Is a split phase motor suitable for use in an air compressor?

A split phase motor is not the ideal choice for use in an air compressor primarily due to its limitations in providing sufficient starting torque. The starting torque requirement for air compressors is typically much higher than what a split phase motor is capable of delivering. Split phase motors are designed for applications that require moderate starting torque, such as fans or small appliances, but they tend to struggle with more demanding tasks.

While some types of motors are designed specifically for high torque applications like air compressors, split phase motors do not meet these requirements effectively. In many cases, air compressors need a motor that can deliver strong initial torque to handle the load of the compressor upon startup, which is critical for efficient operation.

In contrast, a more powerful motor type, such as a capacitor start motor or a permanent split capacitor (PSC) motor, would be better suited for air compressor applications because these motors are capable of providing higher starting torque. This ensures that the compressor can start under the load conditions present when the motor is engaged.
