Abstract

The invention discloses a tubular motor which can separate the brake by non-electromagnetic force, comprising a mounting plate fixed on the wall, a engine base, a housing while a actuating motor, reduction apparatus, output shaft and a brake apparatus are mounted inside the housing. Wherein, the brake apparatus comprises a electromagnet, a spring mounted on the electromagnet, a brake block connected to the spring and a brake wheel relative to the brake block; one end of actuating motor meshes the brake wheel while another end meshes the output shaft via reduction apparatus; one end of draught device which is mounted on the brake apparatus is connected to the brake block while another end outward the housing of tubular motor. Said invention adds a draught device on the brake apparatus of tubular motor, which solves the problem of close door curtain when the power is out. The advantages of invention comprise simple structure, easy operation, long service life, and wide application without increased cost.

Description

technical field

[0001] The invention relates to a tubular motor, in particular to a tubular motor capable of disengaging the brake through non-electromagnetic force. Background technique

[0002] Tubular motor, a device that is fixed on doors and windows after being connected with a reel, and is used to store garage rolling gates, shutters, rolling shutters, awnings, projection screens and other equipment. It is generally composed of a drive motor, an output shaft, a deceleration device and a brake device. The brake device is generally composed of an electromagnet, a spring, a brake pad and a brake disc. Its working process in the electrified state is as follows: before the power is turned on, the The brake pad is frictionally engaged with the brake disc, the tubular motor is in the braking state, when the power supply of the tubular motor is turned on, the electromagnet in the brake device is energized to generate electromagnetic force, the brake pad is attracted by the ele...
