HOME ABOUT US BLOG TERMS PRODUCTS INDUSTRIES CONTACT Products AC Motors – Inverter Capable vs Inverter Duty A VFD-driven general-purpose motor can overheat if it is run too slowly A general-purpose motor can be an Inverter Capable Motor, but it is limited in its speed ratio Inverter Capable 1800 RPM / 10 = 180 RPM as the minimum speed and is usually just fine for Variable Torque applications such as Fans and Pumps Inverter Duty 1800 RPM / 1000 = 1.8 RPM as the minimum speed and is usually needed for many Constant Torque applications such as conveyors, material handling, crane & hoists, machine tools, and compressors. An inverter duty motor can withstand the higher voltage spikes produced by all VFDs and can run at very slow speeds without overheating An inverter duty motor has better insulation on the stator coil – or – to put it in other words, wound with voltage spike resistant insulation systems. Variable Frequency Drive / Variable Speed Drives / Inverters (all the same thing) - were introduced to allow the speed of these motors to be changed while running and to lessen the inrush current when the drive first starts up. To do this, the drive takes the incoming 60Hz AC power and rectifies it to a DC voltage. The DC voltage is then chopped by power transistors at very high frequencies to simulate a sine wave. - By converting the incoming power to DC and then reconverting it to AC, the drive can vary its output voltage and output frequency, thus varying the speed of a motor.
