Abstract
The utility model discloses a novel AC motor that is improved based on the present motor. The AC motor is characterized in that the front part of an electromagnetism lid is respectively provided with a spring, an AC coil, an electromagnetism sucking disk and a brake disc; wherein, the brake disc is connected with a rotor and the other structures are equal to that of the present AC motor. Wherein, the spring is arranged inside the column-shaped protruding platform of the electromagnetism lid, and the AC coil is sleeved outside the column-shaped protruding platform of the electromagnetism lid. The length of the spring is longer that the thickness of the AC coil, and the brake disc is composed of an iron core and a brake sheet that is arranged at the two ends of the iron core. The utility model has the advantages of that, firstly the start electric current is very low and the motor can be started up without adding any resistance accessory; secondly, the starting power of the motor is very steady so that the start impact force can be obviously reduced; thirdly, the electromagnetism restraint current of the motor is very low and the external circuit control of the motor does not obstruct the internal loading performance of the motor; and fourthly, the running and restraining are relatively steady and the application performance is reliable, too.
Description
Technical field
The utility model belongs to technical field of motors, is a kind of novel AC.
Background technology
At present, industry such as lifting, metallurgy particularly, the prior motor power factor is low, speed adjusting performance is poor, even some kind manufacturing process complexity, cost cost height.Some motor is not energy-conservation, be not durable, and causes very big waste aspect operation and maintenance.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, cheap, sturdy and durable, easy to maintenance, and the good novel AC of starting speed adjusting performance is arranged again.
The technical solution of the utility model is improved (only limitting the operation machine) to existing Cone-shaped electric machine, changes cylindrical rotor into by cone rotor; Rotor changes solid rotor into by silicon steel sheet; Change the magnechuck braking into by the braking of taper play; It comprises: motor case stator, solid rotor, front and rear cover, oil sealing, rolling bearing, electromagnetism lid, brake disc, magnechuck, spring, adjustment bolt, adjustment nut.The front end of electromagnetism lid is provided with spring, dc coil, magnechuck and brake disc in turn; Brake disc links to each other with rotor, and other structures are identical with existing alternating current machine.
Aforesaid novel AC, wherein said spring place in the cylindrical end tangs of electromagnetism lid.
Aforesaid novel AC, wherein said dc coil are sleeved on outside the cylindrical end tangs of electromagnetism lid.
Aforesaid novel AC, the length of wherein said spring is greater than the thickness of dc coil.
Aforesaid novel AC, wherein said brake disc is made up of iron core and the brake block that is installed in the iron core two ends.
Aforesaid novel AC, the iron core of wherein said brake disc links to each other with an end of rotor.
Aforesaid novel AC, wherein said magnechuck contact with the brake block of brake disc under the pressure of spring.
The machine operation principle:
The motor shaft end is square or structures such as six splines, ten splines.The iron core hole of brake disc is the keyhole that is slidingly matched with shaft end, because under the pressure of spring, magnechuck is pressed towards brake disc, brake disc is stressed, preceding and rear end cap platform rubs, back and magnechuck friction, magnechuck is owing to can not be rotated by the prevention of three stop columns in the electromagnetism lid, and brake disc has just produced moment of friction.The size of moment is adjusted spring bolt as requested, adjusts to the right place, and nut is adjusted in locking.
During machine operation, the solenoid synchronous working is under the effect in magnetic field, and magnechuck is attracted to electromagnetic core, and brake disc has been eliminated frictional force, and armature spindle rotates smoothly.
Motor is when operate as normal, and delayed firing is by slowly gradually to reach rated speed soon always.
Advantage of the present utility model: 1, starting current is little, but not additional any resistance annex across-the-line starting; 2, starting power is steady, can obviously reduce starting-impact power; 3, the electromagnetic braking electric current is more small, and the outer circuit control of motor does not hinder motor to contain performance; 4, because rotor structure changes, history motor magnetization curve has had very big variation, so by rigid starting, become soft starting; Soft starting can not surpass 1.2 times of rated current, even in the overload, stall 1-2 minute, motor can not burn the line bag, so operation, braking are steady, serviceability is reliable.

Embodiment
Below in conjunction with description of drawings and specific embodiment the technical solution of the utility model is described in detail.
Fig. 1～Fig. 3 is a preferred version of the present utility model, has shown adjustment bolt 1, has adjusted nut 2, places the rotor 14 in the casing 13, and casing 13 two ends are respectively equipped with front end housing 16 and rear end cap 12, and bearing 15 and oil sealing 17 wherein are installed in the front end housing 16; Be connected with brake disc 9, magnechuck 8, dc coil 7, spring 6, electromagnetism lid 5 behind the described rear end cap 12 in turn.
Aforesaid novel AC, wherein said spring 6 place in the cylindrical end tangs 3 of electromagnetism lid 5.
Aforesaid novel AC, wherein said dc coil 7 are sleeved on outside the cylindrical end tangs 3 of electromagnetism lid 5.
Aforesaid novel AC, wherein said brake disc 9 is made up of iron core 4 and the brake block 10 that is installed in iron core 4 two ends.
Aforesaid novel AC, the iron core 4 of wherein said brake disc 9 are slidingly matched with an end of rotor 14 and link to each other.
Aforesaid novel AC, wherein said magnechuck 8 contact with the brake block 10 of brake disc 9 under the pressure of spring 6.
Under the effect of dc coil 7, produce the direction that magnetic field inhales magnechuck 8 to dc coil 7 during work, it is separated with brake block 10 on the brake disc 9, reduce the working resistance of rotor 14, make motor be easy to starting, during end-of-job, dc coil 7 no currents flow through and do not produce magnetic field, and magnechuck 8 contacts with the brake block 10 of brake disc 9 under the pressure of spring 6, and the rotational resistance that has promptly increased rotor 14 is easy to stop.
