Advanced Motor Starters

Advanced motor starters are devices used in the powering up and down of electrical motors.

In the most basic terms, electrical motors are started through the introduction of a current. However, advanced motor starters tend to deal with larger and more complex electrical motors.

What are advanced motor starters used for?

Electrical motors are used in a huge array of modern appliances. Advanced starter motors can therefore be found in devices such as pumps, power tools and fans.

Types of advanced motor starters

The key types of advanced motor starters are:

  • Direct on-line (DOL) starters, which connect directly to the power supply and offer full load to the motor instantaneously
  • Reduced voltage starters (soft starters), which allow the motor to start at a lower-level voltage and gradually increase
  • Variable speed drives (variable frequency drives), which are usually used with three-phase motors and can have their speed and torque altered by the operator using different voltage and frequency inputs.
