EWD series of (outer rotor)the synchronous tractor

It is mainly fitted with the synchronized tractor for the elevator

  • Main feature
  • Major parameter

The traditional elevator tractor is commonly fitted with the asynchronous motor to drive, with the worm wheel and worm to decelerate the traction elevator, therefore its transmission efficiency is low (total transmission rate is lower than 65%), the noise is high (is bigger than 465dBA) because of the contact type. There is some limitation easily to abrade. Our company produces the highly effective non-gear permanent magnetism synchronous tractor (hereafter refers to tractor) with the permanent magnetism synchronous motor to drive, it can raise the driving efficiency greatly (reach as high as above 85%) and reduce the loss above 57%. through the non-contact type's electromagnetic force transmission the noise can be reduced to 10dB so that the abrasion can be avoided, which is one kind of products conforming to the modern environmental protection spirit .This non-tooth tractor with patents is convenient for you to operate by hand in the emergency with a set of device of simple structure and easy operation, realize the emergency control conveniently like the tooth tractor . Each index can be up to the international advanced level, conform to national standards GB7588-2003 (to equate completely in the EN81-1:1998 standard), GB/T13435. With the steady operation, the low noise, the high efficiency, the low temperature rise, the good reliability, and the CE authentication passed. The motor can be matched with German KEB, American EMERSON, the Japanese Fuji, many frequency converter and so on An Chuan, which is best choice for the elevator.
