2.1 AC elevator: An elevator that uses an AC induction motor as its driving force. According to the drag mode, it can be divided into AC single speed, AC double speed, AC voltage regulation, AC variable voltage frequency control and so on.
2.2 DC elevator: A DC motor is used as the driving force of the elevator. The rated speed of such elevators is generally above 2.00 m/s.
2.3 Hydraulic Elevator: An elevator that generally uses an electric pump to drive liquid flow and lifts the car by a plunger.
2.4 Rack and pinion elevator: The guide rail is processed into a rack, the car is equipped with a gear that meshes with the rack, and the motor drives the gear to rotate the elevator to lift the car.
2.5 Screw elevator: The plunger of the straight-top elevator is processed into a rectangular thread, and then the large nut with the thrust bearing is mounted on the top of the cylinder, and then the nut is rotated by the motor through the reducer (or belt), so that the screw top Lift the car up or down the elevator.
2.6 Linear motor driven elevator: The power source is a linear motor.
