Our single-phase range covers 0.18 kW to 5.5 kW for a 220 V single-phase supply; it is used in homes, small workshops, gardens and farms where no three-phase line is available. Current models and prices are on the single-phase 220 V electric motor page.

What sets a single-phase motor apart from a three-phase one:

  • A single-phase supply does not create a self-rotating field; the motor uses an auxiliary winding and a capacitor to start.
  • The current drawn for the same power is clearly higher; cable size and fuse on the 220 V line must be chosen accordingly.
  • At larger ratings, starting current can strain a single-phase line; the connected load of the supply contract should also be considered.

So if a three-phase supply is available on site, a three-phase motor is usually the better choice for the same power. When choosing a single-phase motor, state the power, speed, mounting and whether it starts loaded (e.g. compressor, booster pump). The two types are compared in our three-phase and single-phase motors article.
