Gearless Machine

Gearless machine is permanent magnet synchronous motor and used in draging elevators,so it also is called gearless traction machine.The permanent magnet used in gearless machines is neodymium magnet and the common grade is N38SH,but some famous elevator companies will choose N45SH.Because the max working temperature in elevator is 120°C.The otherwise,the appearance of magnets is block or bread shape.

The gearless machines exist many brands and have their own design,but all of them can’t leave out magnets.At the beginning most of gear machine doesn’t need permanent magnet,but the gearbox should be installed on the machine.So the volume is a little big.Now the gearless machines solve this problem,reduce the volume and save the energy at same time.
