Description
Technical field
The present invention relates to a kind of lift car door switch drive unit, belong to car door switch drive unit.
Background technology
The lift car door switch drive unit that generally uses mostly is threephase asynchronous greatly at present.Mainly there is following shortcoming in this class door lifter with motor: 1, because the motor that generally uses includes complicated deceleration device, so the motor machine volume is big, complex structure, Heavy Weight, cost height, energy consumption relatively also want big.2, usually the door opener of lift car can't satisfy the needs of the permanent moment of torsion of low speed with the temperature rise of asynchronous motor.3, Men control system must be separated with motor and install in order to be had good performance of heat dissipation, so just makes the variable frequency door machine integral layout complicated, and directly has influence on the complicated of whole elevator lay-out, has increased civil engineering area and construction cost.
Along with modern control theory and technology rapid development, and the technological progress of permagnetic synchronous motor design, elevator is already through having adopted permanent magnet synchronous motor more and more, and the gearless machine as traction elevator driving usefulness is able to extensive popularization and application especially.Permanent-magnet synchnorous gearless dragging machine replaces asynchronous motor has the most at last become inevitable development trend, add that society is for requirements of saving energy, in recent years, the asynchronous motor of band deceleration device is just more and more substituted by power factor (PF) height, permanent magnet synchronous motor that efficient is high.
Domestic and international patent documentation by retrieval, the invention of relevant elevator door-motor and motor aspect has over one hundred, closes elevator door-motor and drives the invention of using the permanent magnet motor aspect but find no.
Summary of the invention
Purpose of the present invention is intended to overcome the weak point that prior art exists, and in particular for the blank of filling up prior art, provides a kind of simple in structure, rational and compact, transmission efficiency height, low, the energy-conservation lift car gate operator permanent magnet motor of cost.
Concrete technology contents of the present invention is as described below: a kind of machine permanent magnet motor, comprise that permanent magnet synchronous motor (body), encoder and frequency converter constitute, wherein: permanent magnet synchronous motor, encoder and frequency converter are in one integral body/integral type shell together and are installed on the elevator door-motor; Encoder adopt to hide is gone into the formula structure, that is: the encoder integral installation solid/hide in the inner chamber of End cover for motor, make permanent magnet synchronous motor structure rationally compact, the profile neat appearance; The bottom of frequency converter and the shell of motor have heat radiating fin structure, frequency converter utilization/shared the fin device of permanent magnet motor shell, saved the independent casing of frequency converter, overcome the problem of temperature rise of complete machine simultaneously effectively.
The present invention compared with prior art has following good effect: 1, motor body of the present invention is owing to adopt the dynamo-electric motivation of permanent magnetism door, cancelled the deceleration device that the traditional elevator door lifter is used, make simple and compact for structure, volume is little, in light weight, cost is low, transmission efficiency is high, convenient maintenance and replacement.2, the encoder integral installation used of position displacement feedback signal of the present invention solid/hide in the end cap of permanent magnet synchronous motor, make motor gauge attenuate, help installing and using.3, the holding wire of encoder of the present invention is connected with frequency converter in the inside of permanent magnet motor, the permanent magnet motor profile is more attractive in appearance, structure is more succinct, has particularly avoided causing connecting instability because of the code device signal line exposes, and also makes whole driving, control system more stable.4, the permanent magnet motor power supply is connected with frequency converter by motor casing is inner.5, permanent magnet motor shell of the present invention has the fin device, and the frequency converter bottom has heating panel to link to each other with permanent magnet motor, the shared same heat abstractor of frequency converter and permanent magnet motor, and the frequency converter area of dissipation is big, and control system is more stable.
In a word, door opening machine for elevator permanent magnet motor of the present invention, have simple and compact for structure, machine shape is attractive in appearance, volume is little, in light weight, cost is low, transmission efficiency is high characteristics.
Description of drawings
Fig. 1 is the front view of door machine of the present invention with permanent magnet motor.
Fig. 2 is the vertical view of motor shown in Figure 1.
Embodiment
Shown in the figure: 1, electric motor end cap, 2, encoder, 3, frequency converter, 4, motor (body), 5, the frequency converter back seat.
Further describe detailed technology content of the present invention and execution mode below in conjunction with accompanying drawing.
What above-mentioned accompanying drawing was represented is preferred forms of the present invention, but the profile of this device is not limited to rectangular body, and it also can be the cylinder bodily form or other geometrical body.Door machine permanent magnet motor of the present invention comprises that permanent magnet synchronous motor 4, encoder 2 and frequency converter 3 constitute, and wherein: permanent magnet synchronous motor 4, encoder 2 and frequency converter 3 are in a monolithic case together and are installed on the elevator door-motor; Encoder 2 is adorned in whole or in part, and solid/Tibetan is gone in the inner chamber of End cover for motor 1, and the shell of the bottom of frequency converter 3 and motor 4 has heat radiating fin structure.
The shared heat radiating fin structure of the bottom of described frequency converter 3 and permanent magnet synchronous motor.That is to say: frequency converter 3 mainly dispels the heat by frequency converter back seat 5.Frequency converter back seat 5 dispels the heat with the fin that motor body 4 is connected by the motor body shell.
And described heat radiating fin structure can utilize the original heat radiating fin structure of permanent magnet synchronous motor.So both save manufacturing cost, do not lost U.S. of outward appearance again.
Described door machine permanent magnet motor is characterized in that: the power supply of described permanent magnet synchronous motor 4 is connected with frequency converter 3 by the casing of motor 4 is inner, and more outward appearance is neatly added brilliance.
The holding wire of described encoder 2 is connected with frequency converter 3 by motor 4 body interior, that is to say: encoder 2 holding wires of ensconcing in the electric motor end cap 1 are connected with frequency converter 3 by permanent magnet motor body 4 inside.Permanent magnet motor does not have the connecting line of exposing.
The elevator cab door machine permanent magnet motor that the present invention is above-mentioned; the present invention has only done detailed description with regard to illustrated embodiments; but can not be interpreted as restriction to other modes of the invention process; everyly further improve and similar or identical scheme on basis of the present invention, all being considered as is the scope that the present invention asks for protection.
