Abstract

The invention relates to a highly energy-saving combined stator motor, which comprises a large stator, small stators, a coil winding, an upper shell, a lower shell, a rotor, a bearing for supporting the rotor, a fixing ring for fixing the large stator and the small stators, and a fixing bolt for connection. In the motor, the stators are divided into large and small stator core blocks, an inner coil inserting slot is removed, a coil is directly wound on the large stator from outside, and a plurality of small stators are arranged in the whole large stator, so that the coil is compactly combined with a wire, the slot fullness rate is improved by over 10 percent, the air space is reduced by over 10 percent, the magnetic flux area of the stators is increased, the electromagnetic load is improved, magnetomotive force is increased, the phenomenon of magnetic flux leakage is greatly reduced, eddy current is reduced, and the temperature rise is reduced by over 50 percent; and the wire is directly wound on the large stator, so the length of the coil can be reduced by over 10 percent.

Description

High energy-saving type combined stator motor

Affiliated technical field:

The present invention relates to a kind of novel motor, particularly a kind of household electrical appliance alternating current motor.

Background technology:

Traditional motor all is that coil is bumped into by following wire casing, and this wire casing down is at the stator inner ring, near with the rotor distance, leakage field is serious, and stator is that the overall structure vortex phenomenon is serious, when electric energy changes in the mechanical energy process, produce very big heat energy, cause motor active power low, heating part rapid wear, take, the atmosphere pollution temperature, the waste raw material.

Summary of the invention:

The present invention is directed to above deficiency and a kind of high energy-saving type combined stator motor is provided, this motor is divided into big or small stator core piece with stator, and interior wire casing is down removed, directly be wrapped on the big stator from the outside with coil, in the big stator of the integral body of then a plurality of little stators being packed into, such result is in conjunction with compact between winding wire, copper factor improves more than 10%, and the inter-air space reduces more than 10%, and the stator magnetic flux area increases, electromagnetic load improves, magnetomotive force increases, and the leakage field phenomenon reduces greatly, and eddy current reduces, temperature rise reduces more than 50%. because lead directly is wrapped on the big stator, loop length is saved more than 10%.

Description of drawings:

Referring to Fig. 1, Fig. 2.Wherein Fig. 1 is the vertical view of motor, and Fig. 2 is the front view of motor.1, rotor, 2, little stator, 3, coil windings, 4, big stator, 5, retainer ring, 6, set bolt, 7, go up shell, 8, lower casing, 9, output shaft, 10, bearing.

Specific implementation method:

High energy-saving type combined stator motor comprises: big stator 4, little stator 2, coil windings 3, last shell 7, lower casing 8, rotor 1, the bearing 10 that support rotor is used, the retainer ring 5 of fixing little stator 2 usefulness, the set bolt 6 of connection usefulness.The big stator 4 of this high-efficiency and energy-saving type combined stator motor is outer wire casing overall structure down, coil windings 3 directly is wrapped in big stator 4 grooves, coil windings 3 is close to big stator 4, do not stay unnecessary lead, and by the different magnetic poles distribution, to organize the little stator 2 that is trapezoidal-structure then packs in big stator 4 and the coil windings 3 more, retainer ring 5 is enclosed within big stator 4 and little stator 2 outsides, rotor 1 big stator 4 the insides of packing into, output shaft 9 rotor 1 the inside of packing into, last shell 7 is enclosed within big stator 4 little stator 2 rotors 1 and retainer ring 5 outsides with lower casing 8, rotor 1 supports by bearing 10, bearing 10 is fixed on shell 7 and lower casing 8 the insides, and is last, and set bolt 6 is enclosed within big stator 4, last shell 7, also fixing tight above the lower casing 8.

Claims

1. high energy-saving type combined stator motor comprises: big stator 4, little stator 2, coil windings 3, last shell 7, lower casing 8, rotor 1, the bearing 10 that support rotor is used, the retainer ring 5 that fixing little stator is used, the set bolt 6 of connection usefulness.

2. it is characterized in that: described big stator is outer wire casing overall structure down, and coil windings directly is wrapped in the big stator slot.

3. this high energy-saving type combined stator motor can also have following feature: little stator is trapezoidal-structure for many groups.
