Tube shaped electric machine brake device

Abstract

The invention is a tubular electric machine arrester, comprising rotor component, stator component and brake assembly equipped in an electric machine casing, where the brake assembly comprises brake spring and brake component, the braking spring is jacketed on the upper rod of rotor shaft of the rotor component; the brake component cooperating lower and upper brake components, the lower brake component is installed with metal iron; the bottom end of the upper rod of the rotor shaft is embedded with an iron-attracting electric machine shaft component whose lower end surface is jointed with the upper end surface of the rotor; the iron-attracting electric machine shaft component uses the magnetic force generated by the rotor to attract the metal iron in the lower brake component to be closed; the lower brake component compresses the brake spring to make it break away from the upper brake component. The invention has an advantage of simultaneously generating damping forces on two surfaces and can accurately and quickly brake and save energy and reduce noises.

Description

technical field [0001] The invention relates to a tubular motor braking device, in particular to a tubular motor braking device capable of ensuring accurate, fast, safe, reliable, high-efficiency, energy-saving, noise-reducing and flexible braking. It is used for the braking and braking of various electric rolling shutter doors, rolling shutter windows, garage doors, awnings, etc. that require winding opening and closing. Background technique [0002] The tubular motor is used as the driving device, which is installed in the space of the core of the roll, and has the advantages of compact structure, large torque, and slow speed. In order to ensure that the rolling shutters stop running at the moment of power cut off and stay in this position immediately, prevent the pulled up rolling shutters from sliding due to their own weight, and eliminate the inaccurate positioning caused by the inertia of the rotor after high-speed rotation. In order to ensure the self-locking ability...

AI Technical Summary

Problems solved by technology

However, this tubular motor also uses a single-sided friction device, the braking effect is not ideal, and the friction plate is easy to burn when the motor is no-load. This type is not suitable for light load and no-load

The manufacturing process and assembly process are also relatively complicated, and the production cost is high

It cannot meet the needs of high-efficiency, energy-saving, noise-reduction and flexible braking, and the above-mentioned problems have not been solved.
