Problems solved by technology

[0002] Various elevator frequency conversion door machines are composed of inverters, motors, drive wheels installed and connected to the motor shaft, encoders, and connecting cables. The design mode is to install the inverters and motors separately. The installation is complicated, there are many wirings, and it is easy to break down, especially the output power line with high harmonics is long, which is easy to cause interference to the light curtain and other control systems
The longer the equipment is used, the greater the interference will be, which affects the safe operation of the elevator to a certain extent

Abstract

An integrated elevator conversion door includes the converter, the electric engine, the driving wheel installed the engine axis and the encoder and the wire. The converter is fixed in the engine shell by the door mounting card. The driving wheel and the encoder are installed in the front and back axis end of the engine respectively. The converter is installed in the shield of the door mounting card which the bottom plate is the metal plate with the radiating rib. The invention has the simple structure and low higher harmonic disturbance, so it can be used for the elevator installing widely.

Description

technical field [0001] The invention relates to an elevator door machine driving mechanism, which belongs to the technical field of elevators. Background technique [0002] Various elevator frequency conversion door machines are composed of inverters, motors, drive wheels installed and connected to the motor shaft, encoders, and connecting cables. The design mode is to install the inverters and motors separately. The installation is complicated, there are many wirings, and it is easy to break down, especially the output power line with high harmonics is long, which is easy to cause interference to the light curtain and other control systems. The longer the equipment is used, the greater the interference will be, which affects the safe operation of the elevator to a certain extent. Contents of the invention [0003] The purpose of the present invention is to provide an integrated elevator frequency conversion door operator with compact structure, short connecting cables, c...
