Everything You Need To Know About Single-Phase Gear Motors

October 28, 2022

Electric gear motors are used everywhere and are considered the backbone of the mechanical industry. They use electric energy to provide the mechanical energy required for the operation of tools and machinery. These motors can be distinguished on the basis of feeding phases used by electric motors. In this blog post, let's dive deeper into single-phase gear motors.

An overview of single-phase gear motors

What are they?

Single-phase gearmotors transform electrical energy into mechanical energy through single-phase electrical power. The wiring in these motors is made of only two wires. Single-phase motors are generally used for minimum powers and not high voltage applications. However, some motors can reach high voltages. They usually require a capacitor to start as they cannot create a rotating magnetic field. These gear motors do it by means of an alternating field.

How to avoid problems while using single-phase gear motors?

As mentioned above, single-phase gear motors are ideal for basic electrical applications like homes, commercial stores or small companies. They are not recommended for heavy-duty as the power supply is produced between the equipment and the network directly. These types of motors pose problems just like any other type. But, they are easy to repair. 

Here are some of the most common problems that come with single-phase gear motors. 


  • Wear/breakage of the powertrain gear teeth

  • Wear of the pitch-shaft hole

  • Lack of lubrication

  • Electrical failure

  • Engine malfunction

  • Deformation in the gears


Not exceeding their limitations or sourcing them from a trusted manufacturer are some of the best ways to increase their durability.
