Abstract
A fan and dust board device of an electric motor comprises a machine body and a main shaft, wherein, the machine body is internally provided with a stator and a rotor which is fixed on the main shaft; the main shaft is also provided with a collecting ring, a dust board is installed on the main shaft between the rotor and the collecting ring, and a fan is installed on the main shaft where the dust board is close to one side of the collecting ring. The invention has the beneficial effect that compared with an electric motor which does not have fan and dust board structure, the service life and the running reliability of an electric motor are greatly improved. The surface temperature of the collecting ring is lowered, the rigidity is enhanced, the service time of the collecting ring and an electric brush can be prolonged, the maintaining cost and the running cost are reduced, and convenience is brought to the users, thus saving social resource.
Description
Technical field
The present invention relates to a kind of motor, particularly use fan and dust baffle device on the wound rotor three-phase asynchronous motor of lifting and field of metallurgy.
Background technology
Lifting at present and metallurgy industry just have at widely used motor: lifting and metallurgical with wound rotor three-phase asynchronous motor, lifting and metallurgical with threephase asynchronous, used for electric hoist cone rotor brake 3-phase asynchronous motor, rise and reuse how fast threephase asynchronous, milling train to assist transmission DC motor, crane and metallurgical serial substantially with DC motor etc., and subseries on the basis of the above.AC motor structure is simple, cost is low, working service is convenient, uses the most extensively in the crane electric drive, accounts for more than 90% of motor sum.And the cooling system of these above-mentioned equipment mainly is provided with fan in the fan housing position of bonnet, and this fan can not play the effect of heat radiation to the equipment of brush chamber interior; Simultaneously, brush is through can the friction generation looking carbon powder particle up and down after the long-term use, and these particles can accumulate in the inside of motor, can be present between stator and the rotor, bring potential safety hazard for the operation of motor.
Lifting and metallurgy are to be used to drive the hoisting machinery of metallurgical auxiliary equipment and various types and the special product of other similar devices with wound rotor three-phase asynchronous motor, have bigger overload capacity and higher mechanical strength, be specially adapted to those in short-term or intermitten operation, start continually, brake, the overload sometimes and equipment of remarkable vibration and impact is arranged.
Summary of the invention
The fan, the dust baffle device that the purpose of this invention is to provide a kind of motor solve same minute indoor heat dissipation problem of motor brush commonly used, solve the security hidden trouble that the carbon dust accumulation brings simultaneously.
The objective of the invention is to be achieved through the following technical solutions:
A kind of fan of motor, dust baffle device, comprise body and main shaft, internal body is provided with stator and rotor, rotor is fixed on the main shaft, collector ring also is installed on main shaft, on the main shaft between rotor and the collector ring, dust board is installed, near on the main shaft of collector ring one side fan is installed at dust board.
Beneficial effect of the present invention is: more be not with fan dust board structural electromotor to be greatly improved through useful life and the operational reliability of using motor.The temperature on collector ring surface reduces, and hardness increases, and has prolonged the service time of collector ring and brush, has reduced maintenance cost, has reduced operating cost and has brought convenience to the user, thereby saved social resources.
