Summary of the invention
The object of the present invention is to provide a kind of simple and reliable for structure, little lightweight switching magnetic-resistance formula gearless machine of volume, its rotor do not have permanent magnet and do not have winding, do not receive the temperature rise restriction and speed adjustable range is wide, power factor is high, in whole speed adjustable range, all can keep high efficiency.
To achieve these goals, the invention provides a kind of switching magnetic-resistance formula gearless machine, comprise electrical motor, traction sheave, sensor and at least two drgs; Said electrical motor is a switched reluctance motor; Said switched reluctance motor comprises support, rotor and stator, and switched reluctance motor drives traction sheave rotates provides traction for the elevator operation propulsive effort, and rotor and stator are installed on the support; Sensor is installed in the support; The rotor position information that controller arrives according to sensor carries out the break-make electricity to each phase winding of stator according to certain rule, produces electromagnetic torque and drives rotor rotation; Thereby generation propulsive effort, drg are installed on the both sides of support.
Support and towing machine complete machine base are integral structure, and the support outer round surface is provided with radiating ribs.
Said stator adopts open slot to concentrate winding, and the first end of winding coil is drawn out to connection box respectively, links to each other with controller through connection lead.
Rotor is made up of rotating shaft and rotor core, and said rotor core forms for the salient pole silicon steel plate stacking.
Said traction sheave and brake disc adopt integral type cast structure or split type assembling back machinework, guarantee concentricity and squareness between traction sheave and the brake disc.
Sensor is a magslip.
Drg is caliper brake, folding brake, two drg or axle braking device of pushing away.
Switching magnetic-resistance formula gearless machine of the present invention adopts switched reluctance motor to drive traction sheave and rotates, and rotor is formed by rotating shaft and salient pole silicon steel plate stacking.Compared with prior art, towing machine of the present invention has been removed and has been used the magnet structure of rare earth material, and need not to be equipped with the drop-gear box structure, has simplified the towing machine structure greatly, and the complete machine cost reduces greatly, and the compact conformation volume is little; This uses later-model towing machine can realize the big torque of slow speed of revolution in addition, and its starting current is little, overload capacity is strong, also can realize four quadrant running, frequent rotating operation, and the little efficient of noise is high; And number of stator slots of the present invention is few, and is open slot, and rule efficient is high, adopts and concentrates winding, and the end span is short, also reduces the enamel covered wire consumption, practices thrift cost, improves winding efficiency.

The specific embodiment
The object of the invention, technical scheme and useful technique effect are more clear to be understood in order to make, and below in conjunction with accompanying drawing the technology contents of the present invention and the specific embodiment is described in further detail.Should be understood that the specific embodiment of describing in this specification sheets only is in order to explain the present invention, is not in order to limit the present invention.
Referring to figs. 1 through shown in Figure 3; Switching magnetic-resistance formula gearless machine of the present invention comprises switched reluctance motor, traction sheave 1, sensor 5 and drg 6; Wherein switched reluctance motor comprises support 4, rotor 2 and stator 3; Switched reluctance motor drives traction sheave 1 rotates provides traction for the elevator operation propulsive effort, and rotor 2 is installed on the support 4 with stator 3.Support 4 is an integral structure with towing machine complete machine base, and support 4 outer round surface are provided with radiating ribs, and are simple in structure easy to assembly.
Said traction sheave 1 adopts integral type cast structure or split type assembling back machinework with brake disc, should be noted that the concentricity and the squareness that guarantee between traction sheave 1 and the brake disc.
The stator 3 of switched reluctance motor adopts open slot to concentrate winding, is convenient to realize automatic winding, and the first end of winding coil is drawn out to connection box respectively, links to each other with controller through connection lead.Rotor 2 is made up of rotating shaft and rotor core, and said rotor core forms for the salient pole silicon steel plate stacking, and it can adopt inner rotor core also can adopt outer-rotor structure, need not magnet steel and winding.
Sensor 5 adopts rotating transformer structures to replace the conventional coding device, and sensor 5 is installed in the switched reluctance motor support 4.Controller is according to sensor 5 detected rotor position informations, and each phase winding of stator 3 is carried out the break-make electricity according to certain rule, produces electromagnetic torque and drives rotor 2 and rotate, thereby produce propulsive effort.
Every towing machine need be equipped with 2 above magnet stoppers 6 at least; Drg 6 is installed on the both sides of support 4, and the friction lining of drg 6 relies on spring pressure to contact with motor rotor 2 and produces braking torque during outage, makes the towing machine stall; Energising back friction lining leaves rotor 2, and towing machine rotates.Towing machine of the present invention adopts switched reluctance motor to drive traction sheave 1 and rotates; Thereby for elevator provides propulsive effort; Wherein switched reluctance motor can be realized four quadrant running, can carry out the regenerative brake design, occurs air crash danger when avoiding all electrical equipment et out of orders.When one of them drg broke down, other drg can guarantee that still elevator stops or low speed descends; When all drgs broke down simultaneously, switched reluctance motor was in generating state, can produce certain braking torque, and elevator safety is descended, and the air crash phenomenon can not occur, and is safe and reliable.Drg 6 can be selected caliper brake, folding brake, two drg or axle braking device etc. of pushing away.
