AC elevator: An elevator that uses an AC induction motor as the driving force. According to the dragging method, it can be further divided into AC single speed, AC double speed, AC voltage regulation speed regulation, AC variable voltage frequency regulation speed regulation, etc.
DC elevator: An elevator that uses a DC motor as the driving force. The rated speed of this type of elevator is generally above 2.00m/s. Hydraulic elevator: Generally, an electric pump is used to drive the flow of liquid, and a plunger is used to lift the car.
Gear and rack elevator: an elevator that processes the guide rail into a rack, and installs gears that mesh with the rack in the car. The electric motor drives the gears to rotate and lift the car.
Screw elevator: An elevator that processes the plunger of a straight top elevator into rectangular threads, and then installs a large nut with thrust bearing on the top of the oil cylinder. The nut is then driven to rotate by a motor through a reducer (or belt), thereby causing the screw to lift the elevator car up or down.
The power source of an elevator driven by a linear motor is a linear motor. In the early days of elevators, steam engines and internal combustion engines were used as power to directly drive elevators, but now they have basically disappeared. Motor via reducer
