Door motor for household elevator

Abstract

The invention discloses a door motor for a household elevator. The door motor comprises a base, and a control part, a driving part and a transmission part which are arranged on the base; the control part comprises a controller, a light curtain connected with the controller through a bus, a door closing in-place switch and an elevator running stop switch; the driving part comprises a motor connected with the controller and a reduction gearbox connected with an output shaft of the motor; the transmission part comprises a plurality of pulleys, a belt and a cage door connecting plate; the pulleys are fixed on the two sides of the base; the belt winds around the pulleys; the cage door connecting plate is installed on the belt; the base is made of an aluminum alloy material; the motor is a direct current brushless motor. The door motor is compact in structure, convenient to install, stable in running, low in noise and high in safety coefficient.

Description

technical field [0001] The invention relates to a door operator, in particular to a door operator used for a domestic elevator. Background technique [0002] At present, most common elevators use DC door operators, AC asynchronous frequency conversion door operators and permanent magnet synchronous door operators. For home elevators or villa elevator shafts with small shafts, there are many problems as follows in terms of currently used door operators: [0003] 1) The motor has large volume, low power, poor speed adjustability, and high operating noise. [0004] 2) Separate motor is adopted, the motor and the gearbox are separated, and a small belt is used to drive, which is easy to generate vibration and noise. [0005] 3) The gear transmission method is adopted, the transmission efficiency is low, the noise generated by the gear meshing is large, and the output torque is small. [0006] 4) The pulley is made of hard nylon, which is heavy and has poor self-lubricating pr...

AI Technical Summary

Problems solved by technology

[0003] 1) The motor is large in size, low in power, poor in speed adjustability, and loud in operation noise

[0004] 2) Using a split motor, the motor and the gearbox are separated, and the use of a small belt drive is prone to vibration and noise

[0005] 3) The gear transmission method is adopted, the transmission efficiency is low, the noise generated by the gear meshing is large, and the output torque is small

[0006] 4) The pulley is made of hard nylon, which is heavy and has poor self-lubricating properties. It runs on the guide rail to generate great friction and high running noise

[0007] 5) The overall structure is bulky, takes up a lot of space, inconvenient installation and maintenance
