Description

technical field

[0001] The invention relates to a structure of a traction machine used in an elevator drive system, in particular to a structure of a permanent magnet synchronous gearless traction machine, and belongs to the technical field of elevators. Background technique

[0002] The existing permanent magnet synchronous gearless traction machine is composed of a permanent magnet synchronous motor, a traction wheel, a braking system, etc., and the traction wheel is installed and connected to the rotor end of the permanent magnet synchronous motor through a rotating shaft, which is cantilevered. The current elevators all use a traction machine composed of a motor, traction wheels, braking system, etc. The carrying capacity of the elevator is small, and it cannot meet the strong power required by the high-speed elevator traction machine. Often take place because the number of passengers is many and cause overload phenomenon, the people who have entered elevator also will c...
