Abstract
The utility model relates to an iron core three-phase asynchronous motor with a plurality of stators, which belongs to the field of a motor, and the motor is provided with a plurality of stator iron cores and a plurality of rotor iron cores, wherein, the stator iron cores are respectively wound with stator coils, a rotary shaft of a rotor is provided with the rotor iron cores, both ends of the rotor are respectively provided with end rings, and a conducting bar is arranged between the two end rings. The iron core three-phase asynchronous motor with a plurality of stators, which is matched with a corresponding electric control device, can conduct the quasi stepless speed regulation, and a speed regulation device does not generate harmonic pollution. The utility model has the advantages of simple technology, less investment, convenient maintenance, high reliability, low energy consumption, obvious effect of energy saving, small difference rate of the motor when in full speed, high efficiency and large power.
Description
The utility model relates to a kind of motor, particularly a kind of threephase asynchronous.
At present, widely used threephase asynchronous has a stator and a rotor, and stator has an iron core, is wound with stator coil on iron core; Rotor has a rotating shaft, and an iron core is arranged in the rotating shaft, and there are two end ring the iron core both sides, and the cage bar is arranged between the end ring.When asynchronous motor is carried out speed governing, generally be equipped with frequency converter, frequency converter mainly is made up of power electronic device, produces the harmonic pollution electrical network during work, disturbs electronic equipment, technical sophistication, big, the maintenance difficult of investment.Another kind of winding motor has a stator that is wound with coil, also is wound with coil on rotor, and slip ring is arranged, and is connected with outside by slip ring.The cascade speed regulator of good energy-conserving effect also mainly is made up of power electronic device, this mode of speed regulation poor reliability, harmonic pollution serious interference.
The purpose of this utility model is that a kind of multiple stators iron core threephase asynchronous that harmonic pollution, technology are simple, investment is little, easy to maintenance, reliability is high that do not produce will be provided.
The purpose of this utility model is achieved in that stator has a plurality of stator cores, is wound with stator coil on stator core respectively, and a plurality of rotor cores are arranged on the sliver between two end ring.
A plurality of rotor cores are forward arranged on sliver, and corresponding respectively with a plurality of stator cores.
The asynchronous motor that adopts multiple stators iron core and many rotor cores to constitute in the such scheme, be used with corresponding electrical control equipment, can carry out accurate stepless speed regulation, electrical control equipment does not produce harmonic pollution during to the utility model speed governing, and technology is simple, invests little, easy to maintenance, owing to adopt electrical control equipment that motor is carried out speed regulating control, so the reliability height has reached the purpose of this utility model.Speed regulating device power consumptions is minimum during speed governing, and energy-saving effect is obvious, and technology is simple, maintenance easily, revolutional slip is little at full speed the time, efficient is high, power is big for motor.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Accompanying drawing is a structure chart of the present utility model.
Embodiment: the stator of this motor has two stator cores 1, is wound with stator coil 6 respectively on stator core 1 separately; Rotor has a rotating shaft 4, and two rotor cores 2 are arranged in the rotating shaft 4, and rotor core 2 both sides respectively have has 5, two rotor cores 2 of sliver forward to arrange on sliver 5 between 3, two end ring 3 of an end ring, and corresponding respectively with two stator cores 1.
