Abstract
The utility model relates to an electromagnetic electric brush which comprises an electric brush fixing frame and an electric brush. The utility model is characterized in that one end of the electric brush fixing frame is provided with permanent magnet steel or a fixing iron core, the other end of the electric brush fixing frame is provided with the electric brush, a sliding iron core is arranged between the permanent magnet steel or the fixing iron core and the electric brush, and the sliding iron core and the electric brush are connected as a whole. The position corresponding to the periphery of the fixing frame of the electric brush is wound with an electromagnetic coil of the sliding iron core or an electromagnetic coil of the sliding iron core and the fixing iron core, and the magnetic pole direction of the sliding iron core after excitation is the same with the magnetic pole direction of the fixing iron core. The electromagnetic electric brush reduces the abrasion probability of the electric brush and a commutator and extends the service life of the electric brush and the commutator, and the working performance is stabilize and reliable. By adopting the electromagnetic electric brush, the disadvantages of a motor with a brush are overcome, and consequently, a permanent magnet motor with a brush can better exert the advantages of high efficiency and low cost, and the use range of the motor with a brush can be further enlarged. Especially, the utility model creates conditions for realizing a starting generator with a brush in an automobile field.
Description
Technical field the utility model belongs to the brush that a kind of machine field uses, specifically a kind of disengaging type electromagnetic electric brushes.
Background technology is present, and what existing various brush motors adopted all is traditional type commutator and brush, and also pressing a spring, purpose on brush is that brush and commutator face have excellent contact when guaranteeing that armature rotates.Exactly because the long-term Continuous Contact work of brush motor commutator and brush causes it easy to wear, useful life is short, poor reliability, and then the use field of having limited brush motor.
The summary of the invention the purpose of this utility model is to provide a kind of disengaging type electromagnetic electric brushes, and promptly when machine operation, brush contacts conduction with commutator; When need not machine operation, commutator separates with brush, and brush motor is easy to wear, useful life short, this technical problem of poor reliability thereby solved.
For achieving the above object, the technical scheme that the utility model is taked is: this electromagnetic electric brushes comprises brush fixed mount and brush, it is characterized in that described brush fixed mount one end is provided with permanent-magnet steel or fixed iron core, the brush fixed mount other end is provided with brush, it is unshakable in one's determination to establish a slip between permanent-magnet steel or fixed iron core and the brush, the iron core that slides is connected as a single entity with brush, brush fixed mount periphery corresponding position is wound with the solenoid of described slide solenoid unshakable in one's determination or slide unshakable in one's determination and fixed iron core, and the slip after the excitation is unshakable in one's determination identical with the pole orientation of fixed iron core.
When machine operation, the solenoid energized is slided unshakable in one's determination and permanent-magnet steel or fixed iron core contact jaw generation like pole, and it is unshakable in one's determination under the effect of like pole repulsion to slide, and promotes brush and contacts work with commutator; When need not machine operation, the solenoid power supply disconnects, and the magnetic force unshakable in one's determination that slides disappears, and slides the brush that drives unshakable in one's determination under permanent-magnet steel or fixed iron core suction, and brush is separated with commutator.
This electromagnetic electric brushes has reduced the wearing and tearing probability of brush and commutator, has prolonged the useful life of brush and commutator greatly, stable and reliable working performance.Adopt this electromagnetic electric brushes, overcome the shortcoming of brush motor, thereby make the permanent magnet brush motor bring into play its high efficiency, advantage cheaply better, further enlarge the scope of application of brush motor, have brush starting/generator to create condition at automotive field for realizing especially.
