Abstract
The invention discloses an AC asynchronous differential motor. In a metal shell, two cage rotors in the same parameter share the same stator after being connected concentrically, and another two ends pass through the bearing as the driving shaft. When the moments are the same, the motor's two driving shafts are of the same speed. When the moment of one end is increased, the rotary speed will decline. The rotor's short circuit sensing current is increased to decline the corresponding stator's iron core, voltage at the two ends of the coil, and the rotary speed of cage rotor. Since a bakelite at the middle of the stator iron core divides the iron core into two independent iron cores, the coils thereof constitute serial circuits, the voltage at the two ends of the iron core coil of another rotor will rise, and the cage rotor rotates more quickly. When reaching the needed speed difference, the equal moments thereof stop speeding up. The inductances and voltages at the two ends are the same as well, thus achieving the automatic adjustment of speed difference to realize synchronous operation.
Description
Affiliated field
The present invention relates to a kind of power set that electric automobile drags that are used for, especially adopt the output of birotor both-end, and regulate the AC asynchronous motor that power distribution realizes differential according to actual needs automatically.
Background technology
At present, knownly all need the additional mechanical differential mechanism for electric automobile provides the autosynchronous motor of power, any attachment device all can increase energy consumption and production cost and complete vehicle weight.
Do the deficiency of electric automobile driving apparatus in order to overcome existing autosynchronous motor, the invention provides a kind of AC asynchronous motor, this AC asynchronous motor can realize that without any need for attachment device two concentric driving shafts regulate the output of moments of torsion such as differential and maintenance automatically.
The technical scheme that technical solution problem of the present invention is taked is, in metal shell, two identical cage rotors of parameter are done rotatable concentric connection back, a public stator and are passed bearing respectively and make driving shaft in two ends in addition, and the stator core middle part is added with bakelite and does the magnetic field separator.The two ends driving shaft rotating speed of motor is identical when moment is identical, rotating speed can descend when an end moment strengthens, the short-circuited conducting sleeve induced current of rotor increases, pairing stator core is resisted to be reduced, the both end voltage of winding descends, the cage rotor rotating speed reduces, because of being added with bakelite in the middle of the stator core iron core is divided into two its windings formation series circuits independently unshakable in one's determination, so the winding both end voltage unshakable in one's determination of another rotor correspondence can rise, its cage rotor faster rotational speed, reach needed when difference speed, identical stopping to quicken its moment of torsion, the identical both end voltage of its induction reactance also equated run-in synchronism when diaxon moment was identical, reached automatic adjusting differential, the purpose of constant speed.
The invention has the beneficial effects as follows, can in power conversion, realize differential output, replaced mechanical differential gear box and mechanical deceleration device.Be directly used in fields such as electric automobile, robot; Energy savings, promotion prospect is extensive.
