Abstract
The utility model discloses a novel permanent magnet DC motor for driving furniture. A motion shaft of the permanent magnet DC motor is a worm shaft adopting a worm wheel and a worm to realize transmission and speed reduction output, wherein bearings adopting ball bearings and arranged on the worm shaft are stable in motion, large in moment and longer in service life; a magnetic shoe made of aeolotropic wet-pressing ferrite is arranged on the outer circumference of a stator of the permanent magnet DC motor; and a Hall counting sensor for sending feedback information to an electronic unit is arranged in the permanent magnet DC motor. By adopting the Hall counting sensor, functions such as speed measurement, position memory and moment measurement can be realized at the same time, so that the permanent magnet DC motor provided by the utility model can greatly simplify the debugging and upgrades the reliability compared with a traditional combination of a potentiometer, a gear mechanism and a force sensor.
Description
Technical field
The utility model relates to a kind of furniture drive motors, particularly relates to a kind of novel furniture and drives the permanent magnet DC motor that slows down with band.
Background technology
Electric operator is a kind of common executive component, can be used for automation control area in a large number.The electric operator that is widely used in the domestic industry scene now generally uses the break-make mode to control single-phase or three phase alternating current motor.Adopt the electric operator of this kind mode, in case installation, then governing speed again is unsuitable for modern Based Intelligent Control.Electric driving mechanism is usually used in office, the household furniture that desk, computer desk, conference table, cabinet for television set etc. have elevating function, drives pushrod movement with high-speed electric expreess locomotive as power source usually, thus the balance exercise of the lifting of realization furniture etc.In the course of the work, because running up of motor, can produce stronger vibrations, noise and higher heat, and can not reach meticulous action request, and gear transmission mode is adopted in the transmission that is used for the motor of furniture driving at present mostly, bearing also adopts sliding bearing, is unable to undergo long-term use, can cause the function of effect of attrition motor.
At the shortcoming that prior art exists, this product provides a kind of life-span length and can realize the novel furniture driving permanent magnet DC motor of fine movement.
The utility model content
At the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of life-span to grow and can realize the novel furniture driving permanent magnet DC motor of fine movement.
For solving above technical problem, the technical solution of the utility model is: a kind of novel furniture drives uses permanent magnet DC motor, key is: the kinematic axis of described permanent magnet DC motor is that worm shaft adopts worm gear and worm-drive deceleration output, the stator excircle of permanent magnet DC motor is provided with magnetic shoe, described magnetic shoe material adopts anisotropic wet foundary weight oxysome, in described permanent magnet DC motor, be provided with the Hall sensor for countering, be used for sending feedback information to electronic unit, the bearing of establishing on the worm shaft is a ball bearing.
The beneficial effects of the utility model: this novel furniture drives uses permanent magnet DC motor, the kinematic axis of its described permanent magnet DC motor is that worm shaft adopts worm gear and worm-drive deceleration output, and the bearing of establishing on the worm shaft is that the ball bearing motion is more steady, moment big, longer service life; In permanent magnet DC motor, be provided with the Hall sensor for countering, be used for sending feedback information to electronic unit.The Hall sensor for countering can be realized tachometric survey, position memory and torgue measurement function simultaneously, compares with the combination of traditional potentiometer, gear mechanism and force-sensing sensor, has greatly simplified debugging, and has promoted reliability.
