Abstract
The utility model relates to a cage-shaped combined induction motor. At least two stator sets of different specifications and rotor sets of different specifications corresponding to the stator sets are arranged in a motor casing of the motor, wherein, the stator sets are fixed on a fixed slot at the inner wall of the motor casing, and the rotor sets are fixed on an output shaft of the motor to form the cage-shaped combined induction motor formed by the combination of at least two single units. An insulating circuit board arranged at the outer surface of the motor casing is provided with binding posts for a three phase power supply correspondingly matched with at least two single units in the motor casing, and a micro computer for detecting the condition of load changes and controlling three phase power supply switches corresponding to at least two single units. The motor can input the electrical energy and reduce the waste according to the changes of external load.
Description
The utility model relates to a kind of cage modle composite type induction motor.
In the prior art, three-phase alternating-current induction motor drags in the process at mechanical load, can not change according to loading condition to adjust power output, makes the reactive loss waste of motor very serious.
The purpose of this utility model provides a kind of cage modle composite type induction motor, and its advantage is to adjust combining structure according to the variation of mechanical load, makes motor operate in the optimal economic state under the condition of mechanical load all the time satisfying.
For achieving the above object, the utility model is taked following design: this cage modle composite type induction motor, the rotor set of the stator pack of at least two different sizes and corresponding with it different size quantity is housed in a casing of motor, stator pack is fixed on the holddown groove of casing inner wall, rotor set is fixed on the motor output shaft, constitute a cage modle composite type induction motor that combines by two unit groups at least, the insulation joint plate is installed on the casing outer surface, be equipped with on the described insulation joint plate with casing in the three phase mains binding post of described at least two corresponding couplings of unit group.According to Faraday's electromagnetic induction law and ratio-Sa electromagnetic force law principle, stator pack and rotor set produce electromagnetic torque, the rotation of drive motors output shaft, and the driving machinery load realizes acting.Change according to mechanical load, a microcomputer that detects the motor of load variations situation, the variation of successively decreasing that increases progressively that control cage modle composite type induction motor carries out single group or many group combinations realizes the best of breed that band carries.
The utility model has the advantages that the single group cage modle combined electrical unit that in same casing, is provided with a plurality of different capacities, it is simple in structure, has increased the useful life of motor, has satisfied the needs that mechanical load changes, save the energy, improved the power factor of motor.
The utility model is described in further detail below in conjunction with accompanying drawing.
