PM motors are able to deliver significantly higher energy efficiency values in the pa tial load range and at lower speeds.PM motors have weigh less than conventional induction motors with a comparable power rating. This lower weight makes them ideal for applications where the overall weight is a critical factor.The inherent prope ties of PM motors, such as their compactness and reduced weight, provide machine OEMs with a higher degree of flexibility.PM motors are well known for their wide speed range without compromising efficiency and ensuring a high degree of flexibility in addressing various applications.PM motors accelerate and decelerate quickly, making them the obvious choice for applications where speed and direction change rapidly.With no rotor current losses, PM motors frequently operate at cooler temperatures, extending component lifetimes and reducing thermal stress.
