What is an Inverter Duty Motor

The terms ‘inverter duty’, ‘vector duty’ and ‘1000:1 turndown’ duty may be used interchangeably within the motor community, although these terms mean different things.

Inverter rated often refers to any motor with minimal turndown ratios, such as 10:1 turndown. Whereas 1000:1 turndown offers specific construction and capability. All 1000:1 motors are inverter duty, but not all inverter duty motors are 1000:1 turndown. 1000:1 turndown motors are used in applications where the motor shaft must spin incredibly slow.

What they do have in common is this. These motors provide constant torque, meaning they offer a consistent torque from zero to base speed when operated with a variable frequency drive (VFD). Inverter duty motors also have the ability to provide holding torque. This is when a motor can deliver its full rated torque output when at zero speed without suffering from damage due to overheating.

People are asking:

  • How to tell if a motor is inverter duty rated?
    • Because most motors are now inverter ready, it’s not always indicated on the nameplate. However, if you do see a turndown ratio listed on the nameplate (i.e. 10:1 or 40:1 or 1000:1), this indicates the motor is inverter duty. You may also see ‘CT’ or ‘VT’ listed on the nameplate (constant torque and variable torque, respectively), which is a sign that the motor is inverter rated.
  • What is the difference between inverter duty and general-purpose motors?
    • When an inverter duty motor is running substantially slower than the base speed, the motor will have reduced cooling efficiency. This is because the fan is powered by the motor shaft, and as the shaft speed decreases, so does the cooling ability of the fan.
    • Inverter duty motor wires will be rated for 1600-volt spikes, as they’re coated with high dielectric strength film.
    • Inverter duty motors will have insulation class F or H.
    • High temperature bearing grease will be required.
    • Insulated bearings are required for inverter duty motors.
  • What is the difference between inverter-ready and inverter-duty motors?
    • Most industrial motors made today are ‘inverter-ready’ motors, meaning they are suitable for use for use with VFDs. They can handle variable torque loads over a range of speeds. Whereas ‘inverter-duty’ motors have specific construction and capability. They have special spike resistant insulation systems.

Insulation Class for Inverter Duty Motors

Because VFDs can cause high-frequency voltage spikes in the motor windings, specific insulation is required with inverter duty motors. Class F or class H insulation is required when using inverter duty motors to protect the motors windings.
