Abstract
The utility model relates to a vertical permanent magnet variable frequency three-phase synchronous motor, which comprises a housing and a rotor and a stator which are arranged in the housing. Both front and rear ends of the housing are respectively provided with a front end cover and a rear end cover through bolts. Bearings are respectively arranged in bearing chambers of the front and rear end covers. A rotor magnetic steel is vertically sleeved on a motor shaft. A magnetoelectric encoder connected with an elevator door machine controller is arranged in the rear end cover. A magnetic steel of the magnetoelectric encoder is arranged on the motor shaft. The motor has a simple structure. A mechanical speed reduction mechanism does not need to be additionally arranged. The vertical permanent magnet variable frequency three-phase synchronous motor has reliable performance and long service life.
Description
Technical field
The utility model belongs to a kind of motor, particularly a kind of vertical permanent magnetism frequency conversion three-phase synchronous motor that is used to start elevator door-motor.
Background technology
The motor that uses on elevator door-motor at present is high-speed electric expreess locomotive, and the output speed of motor is very high, needs other additional mechanical reducing gear could realize the switch motion of door machine.Existing elevator door-motor reductor generally adopts the multi-stage, belt deceleration device, the gear reduction box that the employing that also has is traditional.These deceleration devices all have the shortcoming that volume is big, the reverse speedup driving opening of output shaft kinetic moment is big and noise is big, thereby make elevator door-motor system complex structure, failure rate height, maintenance difficult, and the precision of control is relatively poor, and is relatively poor to motor door machine load variations adaptive capacity.In addition, the magnet steel of motor rotor comes off easily, causes the accident.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and a kind of vertical permanent magnetism frequency conversion three-phase synchronous motor is provided, and this electric motor structure simply, does not need other additional mechanical reducing gear, dependable performance.
As above design, the technical solution of the utility model is: a kind of vertical permanent magnetism frequency conversion three-phase synchronous motor, comprise rotor and stator in casing, the casing, the forward and backward two ends of casing are respectively equipped with front end housing and rear end cap by bolt, in the bearing chamber of forward and backward end cap bearing are housed; It is characterized in that: the rotor magnetic steel vertical sleeve is contained on the motor shaft, and the magnetism encoder that is connected with elevator door motor controller is housed in rear end cap, and the magnet steel of this magnetism encoder is installed on the motor shaft.
Above-mentioned magnetism encoder adopts 4096 yards magnetism encoders.
Above-mentioned rotor magnetic steel is four.
Be provided with the gap between the magnet steel of above-mentioned magnetism encoder and the chip of magnetism encoder.
The utlity model has following advantage and good effect:
1, this electric machine structure is simple, volume is little, for low speed designs, need not the switch motion that other additional mechanical reducing gear can be realized a machine.
2, this motor performance is reliable, failure rate is low, can make motor torque reach 8N.M.Simultaneously, can save installation work-hour and Master Cost, reduce the manufacturing cost of elevator door-motor effectively.
3, this motor has been stopped the possibility that magnet steel comes off because rotor magnetic steel is vertically mounted on the motor shaft, has eliminated accident potential, can make rotor reach 52 utmost points, 44 utmost points.
4, this motor is used for measuring with the feedback rotating speed of motor, turns to and the position owing to the magnetism encoder that is connected with elevator door motor controller is housed in rear end cap, therefore can make elevator door motor controller more accurate, thereby make the rate of failure of motor reduce to minimum the control of motor.
5, this motor is owing to be provided with the gap between the chip with the magnet steel of magnetism encoder and magnetism encoder, the magnet steel that therefore can reduce magnetism encoder when rotation and the friction between the chip, thereby prolonged useful life of motor.

Embodiment
As shown in the figure: a kind of vertical permanent magnetism frequency conversion three-phase synchronous motor, comprise rotor 2 and stator 3 in casing 1, the casing, the forward and backward two ends of casing are equipped with front end housing 4 and rear end cap 5 respectively by bolt, and fore bearing 7, rear bearing 8 are housed in the bearing chamber of forward and backward end cap.Four rotor magnetic steel 9 vertical sleeves are contained on the motor shaft 10, and it can axially be charged, and have saved the work of pasting magnet steel, make rotor reach 52 utmost points, 44 utmost points like a cork, thereby have stopped the obscission of magnet steel.4096 yards magnetism encoders 11 that are connected with elevator door motor controller are housed in rear end cap, and the magnet steel 12 of this magnetism encoder is inlaid on the motor shaft, and is provided with the gap between the chip of the magnet steel of magnetism encoder and magnetism encoder.When motor shaft rotates, the magnet steel of magnetism encoder rotates thereupon, the chip of magnetism encoder at any time induction machine rotating speed, turn to and the position, and these signals are inputed to elevator door motor controller, therefore can make elevator door motor controller more accurate, thereby make the rate of failure of motor reduce to minimum the control of motor.
