How Does a Rotary Phase Converter Start? Do I Need a Starter & Motor Starter?

Whatever equipment you have, you should be able to rely on your power source to get the job done. Sometimes, your single-phase utility power alone isn’t enough. You need a rotary phase converter to accelerate the power supply. Keep reading to learn about what this device is, how it works, and why it’s necessary.

What Is a Rotary Phase Converter?

A rotary phase converter is a type of electrical machine that converts electric power from one voltage to another. This device has three main components

  • Stator: The stator is the stationary part of the rotary phase converter which is made up of coils of wire that are wound around an iron core.
  • Rotor: The rotor consists of an iron core with coils around it that are connected to the stator.
  • Something to couple the two components: The means of coupling is what connects the rotor to the stator.

How Do Rotary Phase Converters Start & Why Do We Need Them?

Before diving into the nitty-gritty of rotary phase converter operation, it’s important to understand how they start and why they’re necessary to power certain jobs. Take a look below to learn more:

How Phase Converters Start

A rotary phase converter has two sets of stator coils. One set is mounted on a rotating shaft and the other set is stationary. When the rotor spins, it creates an electrical field that alternates from one stator coil to the next. This then generates a three-phase alternating current (AC). The rotor spins at a constant speed so the AC frequency remains constant regardless of load changes.

Why We Need Single To Three Phase Converters

While most utility power is single-phase, many appliances and electrical equipment require three-phase power to operate. Single-phase sources have one output wire, whereas three-phase sources have three output wires.

By transforming single-phase AC power into three-phase AC power, rotary phase converters provide ample power for appliances and heavy-duty machinery to function properly. In short, single to 3 phase converters provide more power at a faster rate for bigger jobs.

Do I Need a Starter or Motor Starter to Operate a Rotary Phase Converter?

Yes, operating a rotary phase converter requires supplemental power from either a manual or magnetic motor starter. A motor starter is a device that provides the initial torque to get a rotary phase converter rotating. It acts as an auxiliary power source to initiate the rotary converter function.

Some rotary phase converters have a motor starter already built into the mechanism. If your rotary phase converter has a built-in motor starter, you don’t need to acquire a separate one.

How Much Electricity Does a Rotary Phase Converter Use?

On their own, rotary phase converters use very little electricity to operate. Since electricity simply travels through rotary phase converters from the power source to the load, they only need a small amount of electricity the device requires to continue running. In the end, the amount of electricity used by a rotary phase converter depends on the type and size of the device, as well as how much electricity is being converted.

What Voltage Does a Rotary Phase Converter Typically Run On?

Rotary phase converters can operate on a voltage as low as 208 and a voltage as high as 480 or more. Single-phase rotary phase converters typically run on around 208 volts while three-phase rotary phase converters typically run on 480 volts. The voltage a rotary phase converter runs on depends largely upon the application at hand.

Can I Run More Than One Machine at a Time While Using a Rotary Phase Converter?

Yes, you can run two or more machines simultaneously using a rotary phase converter. These devices are designed to work with two or more machines at a given time. Just make sure the size of the device aligns with the size of the load. A rotary phase converter that’s smaller than the load size won’t provide adequate power.

What Other Components Do I Need When Using a Rotary Phase Converter?

The additional components needed to operate a rotary phase converter vary from job to job. However, most jobs require these items:

  • Single-phase power source (i.e. circuit breaker)
  • Metal wire
  • Conduit
  • Connectors
