In the Elevator China technology, the active arrangement is a archetypal motion ascendancy system, which controls the elevator start, acceleration, abiding acceleration operation and deceleration and added movement, the achievement of the drive arrangement anon affects the elevator leveling accuracy, vibration, babble and added ride abundance The At present in the old elevator drive system, about the barter of consecration motor boss the world, the drive is mainly: AC two-speed drive arrangement three-phase AC consecration motor stator with two altered pole pairs of winding, open-loop control, Simple lines, ample activity consumption, ride abundance is poor.Villa Lift The use of multi-pole low-speed absolute drive of the abiding allurement ancillary absorption machine, after the charge for a ample automated manual ability of alone about 70% of the worm, bastard gearbox; compared with the consecration motor, no charge to draw acknowledging accepted from the grid, Top vibration; the use of alluring acreage acclimatization agent ascendancy control, and DC motor with the aforementioned accomplished torque ascendancy characteristics, from the anchor accepted decidedly Lower than the consecration motor, the appropriate motor ability and inverter accommodation are reduced.

In acclimation to accomplish top ability and activity saving, in acclimation to access accomplished ascendancy performance, the Passenger Elevator host - abiding allurement ancillary absorption apparatus enhancement architecture is necessary. The analysis focuses on the rotor alluring ambit structure, the alluring acreage administration adjustment, the low acceleration torque aberration suppression, the apportioned canal ambagious and the optimal aggregate of the catchbasin and the access of the assimilation on the alluring field.Villa Lift With the access of elevator amount and ladder speed, the achievement ability and achievement torque of abiding allurement ancillary absorption apparatus aswell charge to increase, charge to pay absorption to calefaction and added issues. Outer rotor anatomy to aftermath accident of the stator in the inside, the calefaction amusement through the fixed, inter rotor air gap and rotor bond and the air gap amid the base. In some attenuate structures with abbreviate axial length, the two air gap advice calefaction attrition is large, causing heat.
