Small electric motors are compact power sources that take up little room yet do useful work wherever motion is needed. Found in pumps, fans, mixers, short conveyors and bench machines, these motors typically range from 0.55 kW to 7.5 kW and are favoured in both light industry and workshops. DRG Motor builds both three-phase and single-phase versions in this class.

What Counts as a Small Motor?

Here "small" refers to frame size and power range, not a compromise on efficiency or durability. These motors are usually built with an aluminium frame, which keeps them light and easy to handle. IP55 protection and Class F insulation come as standard even on low-power models, shielding the motor from dust and moisture.

Speed and Mounting Options

Small motors are offered as 2-pole (3000 rpm), 4-pole (1500 rpm) and 6-pole (1000 rpm), chosen according to the application's speed requirement. On the mounting side, a B3 foot frame fixes the motor to a bench, while B5 flange and B14 face frames couple directly to a pump or gearbox.

Single-Phase Versus Three-Phase

In workshops and domestic settings without a three-phase supply, single-phase 230 V small motors step in. Where a three-phase 400 V grid is available, three-phase models are preferred for their higher efficiency and smoother torque. DRG keeps both types in stock.

Choosing the Right Small Motor

Even in a small motor, matching power, speed, voltage and mounting type to the application matters. Share your requirement with us and we will pick the most suitable model from DRG Motor's range, starting at 0.55 kW, and deliver it to your bench or machine within a short time.
