Description
Technical field
The present invention relates to techniques of linear motor field, more particularly to a kind of drive mechanism of elevator linear electric motors.
Background technology
With society development and tourist industry rise, urban facilities progressively tend to modernization, hotel, hospital, subway,
R＆D institution, workshop etc. are intended to install can be with the door of automatic shutter, to meet specific demand.
Traditional door machine is typically realized using AC asynchronous motor or dc motor.The former is higher due to rotating speed,
Speed governing and position control are complicated, it is necessary to intermediate reduction gear transmission device, slowed down with reaching and rotation motion is in line fortune
Dynamic purpose, answer this, complex structure, maintenance difficult, noise is big.Though the characteristics of the latter has speed governing aspect, stills need to revolve
Transhipment is dynamic to be converted to the intermediate gearing of linear motion, and also needs to a set of dc source, thus not only complex structure, into
This height, and the maintenance of direct current generator is more difficult than asynchronous machine, in addition also has using hydraulic pressure or pneumatic means come driving gate
, it is compact simple that their driver can be done, but auxiliary device (oil pump or air pump and pipeline) high cost, and structure is multiple
Miscellaneous, volume is big, and in order to ensure that door can be acted at any time, oil pump (air pump) must be constantly in working condition, therefore not only
Noise is big, energy resource consumption also relative increase, has above-mentioned various reasons, is intended to a kind of new driving element, it is not only
With it is simple in construction, noise is small the characteristics of, and energy-conservation again, linear electric motors are exactly a kind of ideal executive component.
A kind of linear electric motors for example disclosed in Chinese patent CN104113180A, including by base band, track, be embedded in base
The carbon that the stator that permanent magnet, strips of conductive piece in band are constituted, by support, coil windings, is coil windings, control circuit to power
Brush assemblies, several bearing pins fixed with support, the mover with the dynamic roller composition coordinated of bearing pin, described its cross section of base band
To be I-shaped, circular arc type track is symmetrically made in I-shaped base band lower cross plate both sides, and symmetrically tiling is inlaid in base band upper table to conducting strip
Face both sides, in a base band segment section be uniformly embedded with some permanent magnets, the magnetic poles of some permanent magnets exposed to crawler belt up and down two
Individual surface；The cross section of described support is to be provided with control circuit, lower recess inner top in H types, the groove of its upper surface
It is fixed with multiple coil windings, lower recess both sides riser is supporting leg, its is longitudinally asymmetric to be formed with some circles for fixed pin shaft
Hole, bearing pin from circular hole fix with some rollers it is dynamic with, described strips of conductive piece is connected for power pole with external power source, described
Carbon brush component be arranged on the front end or rear end of support, carbon brush slidably contacts the surfaces by spring pre-tightening with strips of conductive piece, carbon
Brush holder is connected by wire with control circuit.
One kind for example disclosed in Chinese patent CN104291185B can be travelled vertically again drives with level traveling linear electric motors
Dynamic elevator, be by elevator support, ac motor, horizontal drive wheel, move horizontally guide rail, attachment means, linear electric motor primary,
Straight-line electric echelon level, switch gate car, buffer unit are constituted, it is characterised in that：The described guide rail that moves horizontally is distributed in electricity
Upper and lower two layers of terraced support, linear electric motors secondary connecting valve door car is enclosed within linear electric motor primary, linear electric motor primary two
End is connected to horizontal drive wheel by attachment means, and bottom level driving wheel drives elevator level to travel by ac motor,
Travelled vertically along linear electric motor primary guide rail by the rotation of straight-line electric echelon level again, and drive switch gate car to reach and specified
Position, elevator is travelled vertically, and the bottom of switch gate car is equipped with buffer unit.
The content of the invention
The problem of to overcome traditional line motor in the prior art with：1. efficiency and power factor are relatively low, pipe-shape straight-line
The efficiency and effect factor of motor are than low (when being particularly low speed), its electromagnetism air gap and pole span with the electric rotating machine of capacity
Ratio it is generally larger, required magnetizing current is also larger, increases loss, and primary iron core two ends are cut-off, and produce longitudinal edge
Effect, so that the problems such as causing wave distortion, its result is equally increase loss.2. start thrust and be vulnerable to voltage pulsation shadow
Ring, in the case of the high slippage of low speed, often require that the constant startup thrust of comparison, but when supply voltage has fluctuation, open
Dynamicthrust changes very greatly, it is therefore desirable to which supply voltage is more stable.3. operational speed range is limited by motor pole span, works as electricity
The timing of source frequency one, the speed of service of motor depends greatly on the pole span of motor, and general pole span can not be too big, also not
Can be too small, so its speed is also limited in a certain suitable scope, in the transmission system of low speed is required, just often need
Increase frequency conversion equipment, improve equipment cost.4. feed it is more complicated, for primary linear electric motors, speed it is higher or
When stroke is longer, feed more complicated.5. radiate difficult, linear electric motors of the radiating condition than platypelloid type of pipe-shape straight-line motor
Difference, which limits the electrical parameter that motor allows, so that the thrust of motor is limited, thus the improper big work(of cylindrical linear motor
