Abstract
A low-speed external rotor permanent magnet synchronous motor which is suited to driving an electric automobile and an elevator is provided. The utility model is applied to an elevator, organically integrating a prior motor, a reducer, a scored pulley of a cable wire together with an electronical driver, replacing the conventional elevator, realizing the low-speed stable high pulling torque output. Moreover, the utility model has the advantages of a small volume, a simple structure, etc.
Description
Affiliated technical field
The utility model belongs to energy field, is mainly used in the driving of electric automobile and elevator.
Background technology
At present, known elevator drive is made up of conventional motors acceleration and deceleration device and brake steel wire rope groove wheel, and efficient is low, and it is big to take up room, and needs between special lift.The utility model is equipped with electronic driver to traditional motor, decelerator, the organic combination of steel wire rope sheave, has cancelled traditional escalator, realizes low speed, steady, high pulling torque output.
Summary of the invention
In order to overcome the not enough of traditional elevator driving and to occupy the big defective in space, the utility model provides a kind of low speed outer rotor permanent magnet motor, has realized the organic combination of motor reducer sheave, exports steady low rotation speed large torque.
The technical scheme that the utility model motor adopts is: design of electrical motor becomes multipole, and winding employing joint square is 1 concentrated winding, and multi-channel parallel is adopted in wiring, cooperates electronic driver, directly exports low rotation speed large torque, has reduced decelerator; Adopt outer-rotor structure, the rotor outer ring is a steel design, outer surface processing steel wire rope groove, and the bonding magnet steel of inner surface has been realized the organic combination of motor reducer sheave, volume has reduced, and can be directly installed on elevator top, saves escalator.
The beneficial effect of the utility model motor is: reduced the volume of drive unit for lift, improved efficient, can save escalator.In braking, can become the generator state, with energy recuperation by control.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Figure is structure general assembly of the present utility model, wherein, 1---mounting flange, 2---the steel wire rope sheave, 3---magnet steel, 4---rotor, 5---gear, 6---winding, 7---stator.
Embodiment
In the accompanying drawings, stator (2) is installed on the mounting flange (1); Rotor (4) connects with mounting flange (1) by two bearings (5); The bonding magnet steel of rotor (4) inner surface (3).Go up the connection three-phase alternating current at stator (2), produce rotating magnetic field,, make rotor (4) rotation, output mechanical energy with the intrinsic magnetic field interaction of rotor (4) own; The mechanical energy that rotor (4) rotation produces is transmitted by the steel wire rope sheave (1) that is installed on the rotor cylindrical, thereby drives elevator motion.
Claims (1)
1. low speed outer rotor permanent magnet motor, form by external rotor, magnet steel, stator core, stator winding, bearing and resolver, it is characterized in that: motor outer rotor is the steel construction of band steel wire deep gouge, stator winding employing joint square is 1 concentrated winding, wiring is a multi-channel parallel, and motor internal has braking brake mechanism.
