Permanent magnet synchronous motor (PM) is characterized by its low noise and highly efficient operation. Compared to its counterpart the geared-induction motors, PM motors can save up to 30 to 40 percent of energy. Owing to these advantages, PM motors have been widely used in variety of applications.
PM Motor is a short term for gearless, permanent magnate synchronous motor. Compared with induction motor along with gear box, PM motor is more environmental friendly as it requires no gear oil changes. It is higher in electrical efficient and greatly reduced in overall physical sizes.
In elevator application, PM Motor replaces AC induction motor owing to its several benefits combine -no shaking issues, smooth traction motion, optimum passenger comfort, smaller in size, and lower noise.
“Energy efficient”and”environmentally” friendly are the hype for many industries. The major differences in design with the traditional elevators is the use of the PM motor. It has profoundly advanced and changed elevator operation efficiency.
