Abstract
The invention is used for solving the currently-existed issue that is the asynchronous motor can only drive single load. It comprises: stator, rotator and an external supporting base frame having two ends respectively set with a front end cap and a rear end cap; the rotator shaft of the asynchronous motor is supported by the front end cap of the external supporting base frame via a bearing; on the stator end cap at non-driving end of the asynchronous motor, a stator driving shaft which is coaxial with the rotator shaft; the stator driving shaft is supported by the rear end cap of the external support base frame via a bearing; on the external supporting base frame, a brush is secured; on the exterior of the stator frame, a slip ring fitting the brush is mounted; the line end of the stator winding of the asynchronous motor is connected to the slip ring.
Description
Technical field
The present invention relates to asynchronous motor, be specially the asynchronous motor that a kind of rotor can rotate simultaneously.
Background technology
Existing asynchronous motor is made up of stator and rotor two large divisions, and having only rotor is rotatable part, is used for output mechanical energy and drives load.An asynchronous motor can only drive a load.Many fields comprise that railway locomotive, industrial-mineral electric locomotive, tank etc. often have a plurality of loads, at this moment need to dispose many homotype motors, though satisfying, many homotype motor configurations drive requirement, but unavoidably improve cost, the today that generally appreciate at raw material, cost rises steadily, the product price seriously restricts, reduce cost and to win competitive advantage undoubtedly.
Summary of the invention
The present invention provides a kind of asynchronous motor that can drive two loads simultaneously---the asynchronous motor that rotor can rotate simultaneously in order to solve the problem that existing asynchronous motor can only drive single load.
The present invention adopts following technical scheme to realize: the asynchronous motor that rotor can rotate simultaneously, comprise the asynchronous motor that constitutes by stator and rotor, also comprise the outer support pedestal that two ends are respectively equipped with forward and backward end cap, the rotor shaft extension of asynchronous motor driving end by bearings on the front end housing of outer support pedestal, the stator terminal of asynchronous motor non-transmision end covers and is fixed with the stator power transmission shaft coaxial with armature spindle, the stator power transmission shaft by bearings on the rear end cap of outer support pedestal; Be fixed with brush on the support pedestal outside, be provided with the slip ring that cooperates with brush at the out frame outer surface of asynchronous motor, the line end of the stator winding of asynchronous motor is connected with slip ring.By non-transmision end the stator power transmission shaft is set, is supported on the outer support pedestal, but make the stator of existing asynchronous motor also be in free rotation state and will have asynchronous motor now at existing asynchronous motor.The conduction assembling input asynchronous motor stator winding of electric energy by constituting by brush and slip ring, the stator of asynchronous motor and rotor will rotate simultaneously, and promptly armature spindle and stator power transmission shaft all have torque output, make an asynchronous motor drive two loads.
The asynchronous motor that rotor of the present invention can rotate simultaneously can realize that stator and rotor rotate simultaneously, and two ends moment of torsion output is arranged, and installs, dismantles simply, and easy to operate, maintainability is good.Require under the situation satisfying load traction, the asynchronous motor that rotates during this stator same can replace two AC asynchronous motor of same specification, originally two electric drilling matches changes this kind of homotype motor into, four can change two into, compare mutually owing to reduced big parts such as rotor and stator, cost will reduce greatly, increases the product profit space, increase product competitiveness, help product marketing.The asynchronous motor that rotor can rotate simultaneously is applicable to the occasion that all utilization AC asynchronous motor are used as power, and comprises normal asynchronous and variable-frequency control asynchronous motor.Be particularly useful for the occasion of using two above homotype asynchronous motors to be used as power simultaneously.Every supporting two alternating current asynchronous traction motors of 20 tons of stringing formula industrial-mineral electric locomotives, auxiliary motor is common variable-frequency control asynchronous traction motor.Alternative former two traction electric machines of asynchronous motor that adopt this rotor to rotate are simultaneously compared with original two motors, and new motor has reduced an identical rotor and stator, and therefore cost reduces greatly.
