Abstract
A speed-adjustable low-speed switching reluctance motor integrating the reluctance motor with the planetary speed reducer features that the electronic system if switching reluctance motor is functionally divided into several units which are them installed to the power positions of motor system. Its advantages are simple structure, wide speed-regu9lation range, low speed, large torque, and low cost.
Description
The present invention relates to the reluctance motor field of mechanical, electrical one, a kind of low buncher of switching magnetic-resistance with electronic technology and reluctance motor and planetary reducer combination one.
Switched reluctance machines is the drive system of fast-developing in recent years a kind of electromechanical, what it was different with general reluctance stepping motor is that switched reluctance machines must have position detecting device, with keep rotor-position with each mutually the conducting of exciting current strict corresponding relation is arranged, current pulse width can be regulated arbitrarily, this motor is with simple in structure, easy to maintenance, good speed adjustment features, advantage such as energy-efficient is at household electrical appliance, commercial Application, machinery, metallurgical, weaving, food, Medical Devices, Electric power car, obtained in servo system and the high-speed driving using widely.
The object of the present invention is to provide a kind of electronic technology and reluctance motor and planetary reducer to organically combine the low buncher of switching magnetic-resistance of one, its advantage is to be fit to steady running under the environment of the slow-speed of revolution, big moment, especially the frequent starting of satisfying the demand, fast and reliable braking, fast frequent rotating and in very wide scope, carry out speed governing work.Because new electronic reluctance motor collection stepless speed regulation and deceleration are the whole body.
Technical application scheme of the present invention is: it is a shared support that the support of reluctance motor and reducing gear support are combined together, electronic section is installed in the reasonable position of electric system after by functional anatomy respectively, forms the low buncher of switching magnetic-resistance of electromechanical.1. the support inner chamber of reluctance motor has an annulus wall, inner chamber is divided into long and short two partly, parts such as stator, rotor, axle, end cap, bearing are installed in the long inner chamber are constituted motor, in the short inner chamber planetary gear speed reducing mechanism is installed, be the shared support of reluctance motor and planetary reducer, (planetary gear speed reducing mechanism comprises: the transmission of cycloidal-pin wheel planetary reduction gear, planetary gear transmission, involute planetary gear transmission, Harmonic Gears etc.), the annulus wall played a part reinforcement simultaneously.2. control section (control command, control unit) and electronic device part (power drive, position detecting device) is installed in the casing that plays dustproof damp proof and thermolysis between back end cover for motor and the electric motor fan, operation part (master cock, panel and shows signal) is independent structure, it both can be installed in the switch enclosure on motor surface, also can be installed in control speed governing operation or straighforward operation on the matched host machine, and utilize electric motor fan heat radiation cooling.3. also electronic device (comprising power drive, position detecting device) can be installed in the casing that plays dustproof damp proof and thermolysis between back end cover for motor and the electric motor fan, control section (control command, control unit) and operation part (master cock, panel and signal) are independent structures.It both can be installed in the switch enclosure on motor surface, also can be installed in control speed governing operation or straighforward operation on the matched host machine, and utilized electric motor fan heat radiation cooling.4. also can be in the switch enclosure of electric machine stand with control section (control command, control unit), electronic device part (power drive, position detecting device) and actuating element (master cock, panel, signal) device.
The invention has the advantages that collection stepless speed regulation, motor, reductor are one, compare with advanced in the market frequency converter+motor+reductor or various buncher, buncher, have simple in structure, easy to maintenance, good speed adjustment features, speed adjustable range is wide, energy-efficient, weight saving, easy and simple to handle, reduce manufacturing cost etc.
Be described in detail below in conjunction with accompanying drawing:
Fig. 1: switching magnetic-resistance hangs down buncher embodiment one structure principle chart;
Fig. 2: switching magnetic-resistance hangs down buncher embodiment two structure principle charts;
Fig. 3: switching magnetic-resistance hangs down buncher embodiment three structure principle charts;
With reference to Fig. 1, switching magnetic-resistance hangs down buncher embodiment one, support (1) inner chamber that it is characterized in that switched reluctance machines has an annulus wall, inner chamber is divided into long and short two partly, stator (2), rotor (3), axle (4) and two side end caps (6), (9) and end cap endoporus is installed in the long inner chamber is used for bearing (7), (8) formation motor of bolster (4).In the short inner chamber planetary gear speed reducing mechanism (J) (comprising: the transmission of cycloidal-pin wheel planetary reduction gear, planetary gear transmission, involute planetary gear transmission, Harmonic Gears etc.) annulus wall is installed and is played a part reinforcement simultaneously.One casing (10) is arranged between end cap (9) and fan, apparatus control system A and electronic device B in the casing, wherein control system comprises control command and control unit, electronic device comprises power drive and position detecting device.One switch enclosure (5) is arranged on the electric machine stand, wherein install master cock D and panel.
With reference to Fig. 2, switching magnetic-resistance hangs down buncher embodiment two, and its difference with embodiment one only is that control system A and master cock D are placed in the box (5).
With reference to Fig. 3, switching magnetic-resistance hangs down buncher embodiment three, and its difference with embodiment one and two only is that control system A, electronic device B and master cock D are placed in the box (5).
Operation principle: switched reluctance machines mainly is that transverse axis is different with longitudinal axis magnetic conductance, relies on this magnetic conductance variation generation synchronous torque (also claiming magnetic resistance moment) to keep motor and moves with a certain specific synchronous speed.Cut-off and the closing time of phase current are controlled (available electron circuit or system controlled by computer) by rotor position detector and control circuit.The speed adjustable range of switched reluctance machines is generally between 100-2000, and nominal torque is less, can not satisfy the use of the slow-speed of revolution, big moment, must join reductor in addition, the low buncher of switching magnetic-resistance integrally combines switched reluctance machines and planetary reducer, remedied switched reluctance machines aspect the slow-speed of revolution deficiency and planetary reducer can not speed governing shortcoming, greatly satisfied requiring the machine of the slow-speed of revolution, big moment stably to work.
The present invention can be vertical or horizontal type, can be single-stage or multistage.
