A single-phase electric motor is fed from a 230 V supply through one alternating-current phase and is the choice where a three-phase connection is not available. Domestic pumps, booster sets, small compressors, laundry equipment and workshop benches run on these motors. DRG Motor builds single-phase models for low-power applications.

How a Single-Phase Motor Works

Because a single winding cannot create a rotating magnetic field on its own, the motor's initial movement is provided by an auxiliary winding and a capacitor. The capacitor sets up a phase shift in the auxiliary winding to start the motor turning; after starting, the motor continues to run on the main winding. This arrangement gives a reliable start on a single-phase supply.

Where Is It Used?

Homes, small workshops and farm applications without three-phase power are the main field for single-phase motors. They are ideal for low-power duties such as booster sets, submersible pumps, air compressors, fans and small belt benches. They are usually chosen in the 0.55 kW to 3 kW range.

Construction and Protection

DRG's single-phase motors are mostly built with an aluminium frame, IP55 protection and Class F insulation. This build protects the motor against dust and moisture and gives long life in domestic and light-industrial settings. Mounting is offered as B3 foot or B14 face.

Choosing the Right Single-Phase Motor

In a single-phase motor, power, speed and starting torque must suit the application; the capacitor type matters especially for loads such as compressors that demand high starting torque. DRG Motor recommends the right single-phase model for your need and delivers it quickly.
