The power system of the elevator is the core part of the elevator. The Elevator Manufacturers Fuji takes you to understand the power system of the elevator.

The engine and reducer are installed in the machine room. The brakes and other components of the traction machine are traction drive power. The traction rope is connected to one end of the car by a traction sheave and is connected to the counterweight at one end. In order to place the hoistway and the hoistway respectively on the guide wheel along the hoistway, the two are separated. The weight of the car and counterweight causes the traction rope to be compressed in the traction sheave groove to create friction. In this way, the rotation of the motor drives the traction sheave to rotate, drive the rope, drag the car and move relative to the weight. In other words, the car rises and the weight decreases; the weight increases and the car drops. Therefore, the car reciprocates along the axis track and the elevator transports vertically.

The relative movement between the car and the counterweight is achieved by the friction between the traction rope and the traction sheave. This force is called resistance or driving force. The load of the elevator car in operation and the position of the car and the direction of operation are all changing, and the elevator must have sufficient traction in all cases.

According to the classification of the drive motor of the elevator, the DC traction machine can be divided into a DC wheel traction machine and a DC gearless traction machine. According to the classification of use, it can be divided into two-speed passenger freight elevator elevator traction machine, VVVF trapezoidal traction machine, grocery traction machine, no room traction machine, vehicle elevator traction machine. Classified by structure, it can be divided into horizontal traction machine and vertical traction machine.

Elevator manufacturers will consider various factors when designing the traction system. The traction coefficient of the elevator indicates the traction capacity of the elevator. The factors affecting the traction coefficient are generally fixed. Therefore, as long as these factors are controlled, the corresponding traction coefficient can be obtained. . The rated power of the elevator traction motor is based on the maximum power output of the traction motor at full or no load.

A new generation of linear motor drive, no traction rope elevator, machine room, counterweight and traction rope, simple structure, easy maintenance, no noise, no pollution, save energy.

Fuji will continue to improve the traction system of the elevator, making the elevator more energy efficient.
