Abstract
The utility model provides a solid rotor electric motor having a rotation and braking cycle function. The solid rotor electric motor comprises a machine base, a fan, a fan housing and a stator, wherein a solid rotor of the electric motor is connected with a brake disc; the brake disc is connected with a brake spring; the brake spring is sleeved on a rotation shaft; and a friction plate is connected with the brake disc. The brake spring that is connected with the solid rotor and the brake disc is compressed under the effect of a magnetic pulling force, looses the brake disc and enables the electric motor to run; and when the magnetic pulling force is disappear, the elastic force recovers, so that the brake disc resets and generates a braking moment of force and the electric motor is enabled to be in a braking state; the brake disc is used for transmitting the braking moment of force; and the friction plate is adhered to an inner plane of a rear end cover of the electric motor and is used for enhancing a braking effect and prolonging service life.
Description
Technical field
The utility model relates to YSE, YSE
2, YSE
380-100 series solid rotor brake motor and YDSE, YDSE
2, YDSE
3The how fast solid rotor brake motor of 80-100 series field is specifically related to a kind of the rotation and the solid rotor motor of braking circulatory function.
Background technology
In lifting and the metallurgical threephase asynchronous field of using, driving in the world, speed governing, braking three functional unification motor (being called for short three-in-one motor) are in a leading position level.YDSE, YDSE
2, YDSE
3The speed regulating method of 80-100 series motor is pole changing, can be referred to as three-in-one motor.Give the motor brake function aspects, with regard to the principle aspect in its braking force source, can be divided into self directly providing and adding dual mode is provided indirectly; And the pattern that self directly provides is divided into cone rotor again and moves axially with solid rotor magnetic field and move two kinds of forms.Under braking principle and structure situation that same industry competition research more has superiority, produced this side magnetic-type solid rotor brake motor.
But, at present solid rotor brake motor, complex structural designs, fluctuation of service, the failure rate height, the motor life-span is short, and power consumption is big, the cost height.These technical problems are perplexing the development of this kind motor, bring great inconvenience and trouble for the motor industry.
The utility model content
The utility model solves above technical problem, and having proposed a kind ofly directly provides the principle of braking force by motor itself, under the condition of connecting power supply, produces axial magnetic pull, and the power supply motivation is rotated and the braking function use.
Based on above-mentioned purpose, the utility model is realized above-mentioned target by special structural design:
A kind of rotation and the solid rotor motor of braking circulatory function comprises support, fan, fan housing, stator, and the solid rotor of motor connects brake disc, and brake disc connects tripping spring, and tripping spring is set in the rotating shaft, and friction plate connects brake disc.
Further, described friction plate is arranged on motor rear end plate inside.
Further, described solid rotor is provided with the aluminium sliver, constitutes cage rotor.
The beneficial effects of the utility model are, move more reliably, lower failure rate, 5 minutes motor burning-tolerants of stall; Owing to self directly provide braking force, saved energy resource consumption and motor operation cost, realized that motor rotates and the circulatory function of braking; Since simple in structure, the about 20%-30% of manufacturing cost reduced, greatly reduce the market sale price of motor.
And, at the motor brake end, offer some rotor aluminium slivers on the solid rotor, constitute a bit of cage rotor behind the casting aluminum rotor.This " a bit of cage rotor " just can produce axial magnetic pull under the energising situation, hold brake disc, makes motor operation.
The tripping spring that solid rotor, brake disc connect, by compression, the take-off the brake dish makes motor operation when being subjected to magnetic pull; When losing magnetic pull, spring return makes brake disc reset generation braking moment, makes motor be in on-position; Adopted brake disc, in order to transmit braking moment; With motor rear end plate inner plane, the friction plate that bondd, to strengthen braking effect and useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model solid rotor.
Embodiment
Below by Figure of description 1,2, further illustrate the utility model.
As shown in Figure 1, 2, a kind of rotation and the solid rotor motor of braking circulatory function, comprise support 5, fan 9, fan housing 10, stator 4, the solid rotor 3 of motor connects brake disc 6, and brake disc 6 connects tripping spring 2, and tripping spring 2 is set in the rotating shaft 1, friction plate 7 connects brake disc 6, friction plate 7 is arranged on motor rear end plate 8 inside, and solid rotor 3 is provided with aluminium sliver 11, constitutes cage rotor.At the motor brake end, offer some rotor aluminium slivers 11 on the solid rotor 3, constitute a bit of cage rotor behind the casting aluminum rotor.This " a bit of cage rotor " just can produce axial magnetic pull under the energising situation, hold brake disc 6, make motor operation, the tripping spring 2 that solid rotor 3, brake disc 6 connects, when being subjected to magnetic pull by compression, take-off the brake dish 6 makes motor operation; When losing magnetic pull, spring return makes brake disc 6 reset generation braking moments, makes motor be in on-position; Adopted brake disc 6, in order to transmit braking moment; With motor rear end plate 8 inner planes, the friction plate 7 that bondd, to strengthen braking effect and useful life.
The operation principle of this engine is: motor energising → solid rotor produces axial magnetic pull → tripping spring compression → brake disc and gets loose → the motor entry into service, the motor outage, tripping spring resets, brake disc extruding rear end cap brake(-holder) block, produce braking function, motor shuts down.
The above only is preferred embodiment of the present utility model, does not limit the utility model.All any modifications of within the utility model spirit and principle, making, be equal to replacement and improvement etc., all be included within the protection range of the present utility model.
