Elevator motors profile

Elevator overview of the development
Elevator motor due to the use of special occasions, elevator motor should have a little vibration, low noise, small starting current, starting torque and enough smooth running performance requirements. Permanent magnet synchronous elevator motor has torque ripple, steady speed, dynamic response quickly and accurately, strong overload capacity, etc., not only to meet the above requirements, but also can significantly improve the power factor, reduce losses and improve efficiency the long run, you can play down the synergistic effect. Meanwhile, the sine wave PMSM vector control in accordance with a variety of methods to constitute frequency control system, high-performance, high-precision drive, the dynamic response requirements of the occasion of its application particularly promising.
     Elevator motor and control technology
Lift the development history, in fact, the elevator motor and control technology development history.
     Elevator motors, according to the type of motor points, can be divided into the DC elevator motor and AC elevator motor two categories. According to the elevator motor driven gear traction machine without a gear-driven and can be divided into gearless drive in two, according to the different control methods can be divided into two-speed elevator motor, the voltage controllable elevator motors and variable speed elevator motors.
