Product Description
Escalator spare parts 7.5/9.5KW escalator motor
1.Principle
The permanent magnet synchronous gearless traction machine, which includes inner/outer rotor structure, comprises permanent magnet synchronous motor, brake system, traction sheave and etc. It is designed solely for use with AC frequency inverters and encoders to do the job of test, feedback and control, and it works with synchronous speed by fitting with permanent magnet synchronous motor with has the same character of linearity, constant torque and variable speed with dc motor. The traction machine with the advantage of DC and AC motor, functions by the steel rope which rubs against the traction sheave that is driven by the motor directly to drag the lift car go up and down.
2.Applications
Our machines are applicable to all types of passenger elevator, medical elevator, freight elevator that are controlled by frequency inverter.
Product Advantages:
1.Constant Torque
2.Small Dimensions
3.Free of maintenance
4.Lower Noise
5.Environmental Protection
6.Running Steadily
7.High efficiency
8.Safe and reliable
9.Energy saving
10.Wide-speed applicable
What is Permanent Magnet:
magnets used in the elevator is usually used in the operating temperature of up to 140 degrees, the life of demagnetization rate does not exceed 1% of the products, so we think it remains permanently magnetism in normal operating temperature . So called permanent magnet
What is Synchronization:
The interaction of two magnetic fields, the rotor is dragging synchronized with the rotation of the armature rotating magnetic field.
