Motor Specifications

Depending on the type of machine and application you require, some motors will work better than others. If you are running smaller equipment that requires less horsepower, a single-phase motor will work best for your needs. While this type of motor typically lasts for years, over time it will wear out.

These motors are typically used in devices and equipment that require lower levels of horsepower, or when it is inefficient to use a three-phase motor. Single phase motors have a similar construction to the three phase motor.
