Abstract

The utility model relates to a cone disc energy-saving brake motor, which relating to the field of a brake motor. The utility model is a new brake motor with cone brake accepting a side magnetic principle. The utility model is mainly characterized in that a detached magnet and an armature iron are arranged in a motor rotor; the detached magnet and the armature iron are separated by a spring. A brake cone disc and the cone face of a back end cover of the motor are mutually contacted; the cone disc is tightly fixed on the armature iron. The detached magnet generates axial suction force after the motor is conducted, causing that the armature iron is closed; the cone disc is separated from the back end cover; the motor can normally run; the armature iron is released after power cut; the cone disk is tightly contacted with the back end cover, achieving that fast brake. The back end of a motor shaft is provided with a regulating screw; the motor shaft can be screwed into the screw, causing that the cone disc is always separated from the back end cover; a brake function can not be generated; thereby, the utility model can be used as a common motor.

Description

Awl coils energy-conservation brake motor

The utility model relates to the braking motor field, and a kind of a kind of novel energy-conserving brake motor of adopting the braking of other magnetic principle awl dish is the significant improvement of magnetic braking motor, has high energy-saving effect and use value.

Braking motor is a kind of motor that self has brake mechanism, and it is widely used in requirement and stops fast, makes spindle drive or accessory drives in the various machineries that prevent to slide.As being used for machineries such as lifting lifting, building, metallurgy, transportation, food, medicine, chemical industry, existing braking motor mainly contains: a class is the braking motor that additional direct current of motor non-shaft stretching end or ac brake are formed; The another kind of braking motor of forming by cone rotor additional brake element, its major defect be cost height, complex structure, fragile, volume is big, wants consumed power during work.

The purpose of this utility model is to provide a kind of a kind of novel energy-conserving braking motor of adopting the braking of other magnetic principle awl dish, it is simple in structure, easily manufactured, not fragile, in motor operation course, do not need consumed power, the sensitivity height, but fast braking, but also brake off, braking moment is big, and is safe and reliable.

Embodiment of the present utility model: one, motor rotor is equipped with branch magnet.Dividing the effect of magnet is the stator radial flux, changes into axial magnetic flux through undue magnet, to produce axial magnetic suction.Behind motor connecting power, promptly produce a kind of rotating magnetic field, under the effect of minute magnet, the magnetic flux of rotor portion just produces an axial magnetic pull, and armature is sucted, and armature connects the awl dish, at this moment throws off rear end cap, the motor entry into service.After the outage, magnetic field disappears, and under the effect of spring, armature is pushed open, makes the conical surface of drag cone dish contact rear end cap, thereby makes the rapid stall of motor.

Two, the rotor shaft rear end is equipped with rotary screw, advances pin and pin, if do not brake when using, but the clockwise direction rotary screw advances pin and pin drive awl dish and armature to rotor to divide magnet to break away from rear end cap, make motor be in not on-position, otherwise promptly restore to the original state.Advantages such as complete machine structure has and is active in one's movements, and braking moment is big, and is safe and reliable need not other coil and produce magnetic field and brake, thereby make energy saving motor.

Three, any motor (comprising y series motor, magneto series, fire-proof motor series, buncher series, reducing motor series) all can adopt this scheme, and motor can be vertical or horizontal.

The utility model is compared with electromagnetic type braking motor or cone rotor electromagnetic type braking motor, and its advantage is: 1, economize on electricity 20 ~ 30%; 2, simple in structure, easily manufactured, cost low 60 ~ 70%; 3, braking moment is big, is active in one's movements, and is safe and reliable, not fragile; 4, volume is little, and complete machine is identical with various motors, compares with electromagnetic braking motor, and volume is little by 70 ~ 90%; 5, consumed power not;

Accompanying drawing is a structure principle chart of the present utility model.

Referring to accompanying drawing, awl coils energy-conservation brake motor, it is characterized in that:

One, motor rotor (1) is equipped with branch magnet (2).Dividing the effect of magnet is stator (3) radial flux, changes into axial magnetic flux through undue magnet, to produce axial magnetic suction.Behind motor connecting power, promptly produce a kind of rotating magnetic field, under the effect of minute magnet, the magnetic flux of rotor portion just produces an axial magnetic pull, and armature (4) is sucted, and armature connects awl dish (5), at this moment throws off rear end cap (6), the motor entry into service.After the outage, magnetic field disappears, and under the effect of spring (10), armature is pushed open, makes the conical surface of drag cone dish contact rear end cap, thereby makes the rapid stall of motor.

Two, awl coils energy-conservation brake motor and it is characterized in that: the rotor shaft rear end is equipped with rotary screw (7), advance pin (8) and pin (9), if do not brake when using, but clockwise direction rotary screw (7) advances pin (8) and pin (9) to drive awl dish (5) and armature (4) to rotor divides magnet (2) to break away from rear end cap (6), make motor be in not on-position, otherwise promptly restore to the original state.Advantages such as complete machine structure has and is active in one's movements, and braking moment is big, and is reliable fully need not other coil and produce magnetic field and brake, thereby make energy saving motor.

Three, awl coils energy-conservation brake motor and it is characterized in that: any motor (comprising y series motor, magneto series, fire-proof motor series, buncher series, reducing motor series) all can adopt this scheme.Motor can be vertical or horizontal.

Claims

1, a kind of awl coils energy-conservation brake motor, form by stator (3), rotor (1), branch magnet (2), armature (4), spring (10) and rear end cap (6), wherein: rotor (1) is fitted together with dividing magnet (2), spring (10) places between branch magnet (2) and the armature (4), it is characterized in that: friction pair is made of awl dish (5) and rear end cap (6), the awl dish connects one with armature, and spring compresses friction pair during outage, and motor is in on-position.

2, awl according to claim 1 coils energy-conservation brake motor, it is characterized in that: the armature spindle rear end is equipped with screw (7), is advanced pin (8) and pin (9), pin (9) connects with armature (4), during along pin rotary screw (7), screw (7) holds out against successively and advances pin (8) and pin (9), to the friction pair separation, so motor loses braking function.
