Embodiment Construction

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] Such as figure 1 As shown, the reel-type forced-drive permanent magnet synchronous gearless traction machine includes a permanent magnet synchronous motor 1 , a frame 2 , a reel 3 , an electromagnetic brake 4 , an encoder 5 , and a manual release device 6 .

[0019] The machine base 2 is an integral casting; the reel 3 is directly fixed on the main shaft of the permanent magnet synchronous motor 1, and is integrated with the machine base 2 through the support of the bearing. There is a spiral traction groove on the reel 3, and the shape of the traction groove is It matches the shape of the steel wire rope selected by the elevator, and the number of traction slots is determined by the load and lifting height of the elevator; the shell o...

Abstract

The invention discloses a winding drum type forced driving permanent magnetic synchronous gearless machine which comprises a permanent-magnetic synchronous motor, a winding drum, a coder and an electromagnetic brake which can limit the rotation action of the winding drum; and the winding drum is directly fixed on the main shaft of the permanent-magnetic synchronous motor and is provided with a spiral haulage groove, the shape of the haulage groove is matched with the shape of a wire rope selected by an elevator, and the coder is connected with the main shaft of the permanent-magnetic synchronous motor. Compared with the existing elevator traction machines, the winding drum type forced driving permanent magnetic synchronous gearless machine has the obvious technical features as follows: 1, the winding drum type forced driving is adopted; 2, the permanent-magnetic synchronous motor is adopted to directly drive, and the gearless machine does not have a gear box; and 3, the volume is small, the processing assembly is simple, the raw material cost is reduced, meanwhile, the cost of the elevator is reduced, and the space is greatly saved. The gearless machine provided by the invention is suitable for home elevators or villa elevators with small elevator shaft passage.

Description

technical field [0001] The invention relates to an elevator traction machine, in particular to a permanent magnet synchronous elevator traction machine without an acceleration and deceleration box which adopts a reel-type forced drive, and is especially suitable for household elevators with small elevator shafts. Background technique [0002] At present, the traction machines used in home elevators (or villa elevators) on the market mainly have the following forms: [0003] 1. Hydraulic type, its disadvantages include troublesome maintenance and installation, risk of oil leakage, not environmental protection, etc., this form has not been widely used at present; [0004] 2. Traction type, there are permanent magnet synchronous gearless traction machine and asynchronous geared traction machine. The disadvantage is that the elevator needs to have a counterweight, which not only occupies space in the hoistway but also wastes certain resources. In addition, the asynchronous has g...
