Abstract

The utility model relates to an electric motorin a movement type, which comprises an outer shell (1), a stator (2) and a rotor (4). The utility model is characterized in that a spring (6) is arranged on a shaft (5) of the rotor (4), a thrust bearing (7) is arranged between the spring (6) and the rotor (4), and the length of magnetic jaws (3) of the electric motor is different. The electric motor can cause the rotor to move when electricity is electrified to work, so that transmission wheels of the electric motor can be driven to automatically engage and disengage. The utility model is suitable for being widely used in working fields requiring engaging and disengaging transmission.

Description

The rotor displacement motor

The utility model discloses a kind of rotor displacement motor, belong to technical field of motors, be particularly suitable for making the motor that power and load frequent clutch place are used.

Existing motor does not all have the rotor displacement characteristics, when power and load frequent clutch, often realizes that by the clutch of cutting off the electricity supply or operational power connected this not only increases equipment investment, and troublesome poeration, and fragile equipment cause damage.

The purpose of this utility model provides a kind of rotor displacement motor, and the rotor of this rotor displacement motor can be subjected to displacement, and directly realizes motor and load-carrying automatic clutch with this, both reduced investment outlay, and easy and simple to handle.

For realizing that the purpose of this utility model has adopted following technical scheme:

On rotor, increase upper spring, the magnetic pawl of motor stator is caused non-isometric magnetic pawl, make the rotor displacement motor.

Further describe technical characterictic of the present utility model below in conjunction with accompanying drawing:

Fig. 1, the structural representation of an embodiment of the utility model;

Fig. 2, the structural representation of an embodiment;

Fig. 3, the AOA cross-sectional schematic of embodiment.

In Fig. 1,2,3 structural representation, 1 among the figure is motor housing, and stator 2 and magnetic pawl 3 are arranged in motor housing 1.Magnetic pawl 3 is divided into two groups up and down, the placing in the shell 1 of intersection.Among the figure 4 is rotors, and the utility model is to be equipped with spring 6 on the axle 5 of rotor 4, between spring 6 and the rotor 4 abrasionproof thrust bearing 7 is arranged.The length difference of the magnetic pawl 3 that the utility model is used, the magnetic pawl length that is equipped with spring 6 one ends at axle 5 is short, and the length of a relative end magnetic pawl is long.Rotor 4 of the present utility model is a permanent magnet.

Under the normal condition, spring 6 withstands rotor 4 through thrust bearing 7, makes rotor 4 be in a side of casing 1, and the rotor 4 of motor does not rotate; After stator 2 energising, on magnetic pawl 3, produce induced field, the intersection year magnetic field of two groups of magnetic pawls is the strongest, and this high-intensity magnetic field produces galvanomagnetic effects with rotor 4, on the one hand rotor 4 is pulled to strength, magnetic field, makes rotor 4 displacements, and rotor 4 is rotated, and begins to do work.

Fig. 2, Fig. 3 are embodiment of the present utility model, at axle one of 5 ends of rotor 4 a clutch card 8 are arranged, and drive 9 is combined together through bearing 12 and axle sleeve 10, and can rotate around axle sleeve 10 easily.Axle 5 and slidably displacement of axle sleeve 10.Projection 11 can cooperate with clutch card 8.When motor was static, because of the effect of spring, clutch card 8 left projection 11, is disengaged position; Motor is done man-hour, because the displacement of rotor 4, clutch card 8 contacts with projection 11, makes drive 9 with rotor 4 rotations.

The utility model has following advantage:

1, simple in structure, to make easily, cost is low, is convenient to promote;

2, reduce middle arrangement of clutch in the use, reduce equipment investment, easy to operate.

Claims

1, a kind of rotor displacement motor, it contains casing (1), stator (2), rotor (4), axle (5) and magnetic pawl (3), it is characterized in that: described rotor displacement motor is that the axle at rotor (4) is provided with spring (6) on (5), and magnetic pawl (3) is made two groups of magnetic pawls of varying length, makes the rotor displacement motor.
