Abstract

The present invention relates to a kind of efficient energy-saving motor, its technical characterictic is a kind of upper guide plate that combination such as sheet metal is arranged, bottom guide assign in the silicon steel sheet of rotor cause rotor structure inside series change and cause the utility model under equal motor service condition, on average economizing on electricity more than 23%, fan-out capability is big, torque increases, low about 12-45 ℃ of temperature, starting current is less than more than 42%, frequent starting 60 times/minute, electric current is lower than about 45%, the phase failure is operation as usual, connects single phase poaer supply operation as usual.

Description

Efficient energy-saving motor

The present invention relates to a kind of motor.

Motor comes out so far, and its kind is a lot, in up-to-date technology, its rotor mostly is location skeleton overall structure greatly, and is not fragile.But torque is little during the operation of this kind motor, and not only the big temperature of electric current is also high for the big big energy-consuming of starting current, Fraquent start, influences useful life, increases corollary equipment and maintenance cost, and the phase failure is easy burn-out also.German En Te, this invention of the Chinese changes the permanent magnet installation skeleton (patent No. is 82202668.5) of knockdown type two-stage rotor into but only solves cost and make things convenient for problem.On April 23rd, 1992, China king such as stayed greatly at the multi-function, efficient energy-saving electric motor of 8 inventions, (patent No. is 92208287.1 and 92103083.5) though solved some problems, also not very good at energy-conservation, temperature starting current etc.

The deficiency that the objective of the invention is further to overcome above-mentioned technology provides a kind of power savings better, and starting current is the also low efficient energy-saving motor of low-running-temperature more.

The technical scheme of being taked is for achieving the above object:

Include shell, stator and rotor with above-mentioned 92208287.1 and No. 92103083.5 the same, provided by the present invention motor of the described motor of patent, said rotor core is divided into plurality of sections, be provided with one between per two sections adjacent rotor iron cores and be with trochantinian insulated metal ring in the heart hole therein, it is characterized in that:

(1) said becket is outer guide plate assembly 3, its structure is: there are some blocks of copper or aluminium annular membrane 4-C in the centre, by high-temperature plastic ring pad (plate) or asbestos ring pad (plate) 4-A, above-mentioned polylith annular membrane is isolated, the two sides skin of this glue ring pad (plate) is porose on every side silicon steel ring plate 4-D, and the hole is sealed with aluminium or copper-clad.

(2) said lesser trochanter is an inner guide plate assembly 2, an one aluminum skeleton 8-A, and the garden tube 8-B that is integral the less porose 8-C of diameter by a garden sheet and with it constitutes.Embed some its silicon steel chip 8-D that circle hole 8-E arranged and axis hole 3-C is arranged in the tube of said garden on every side, be inserted in some its silicon steel ring plate 4-D that circle hole arranged and hole, garden 4-B is arranged outside the tube of garden on every side, Kong Junyong aluminium or copper-clad envelope.

If installing is made up between the end ring 1 at rotor two and silicon steel sheet 4 outer guide plate assembly 3 and inner guide plate assembly 2, motor performance of the present invention is better.

Adorn inside and outside guide plate assembly preferably for the 3-9 cover, the length of the silicon sheet core 4 between the inside and outside guide plate assembly of per two covers are 3～2000 millimeters.

After the present invention adopts abovementioned technology, thereby changed the motor-field form.Improved the electromagnetic induction active force, be issued to following effect in equal motor conditions:

(1) little power consumption, average energy-conservation more than 23%, (2) starting current is low more than 42%, and fan-out capability increases.(3) torque increases, 60 times/minute meters of Fraquent start, electric current low about 45%.(4) temperature is low 12～45 ℃, (5) phase failure safe operation that does as usual, and (6) connect single phase poaer supply operation as usual.The big more effect of power of motor is good more.

Fig. 1 is for analysing and observe total figure in rotor of the present invention front;

Fig. 2 is the end ring front view;

Fig. 3 is the silicon steel sheet front view;

Fig. 4 is the longitudinal section of outer guide plate assembly;

The invention will be further described below in conjunction with accompanying drawing:

Shown in figure (2) (3): the polylith silicon steel sheet 3-A of rotor is poured into silicon sheet core 4 with metallic aluminium or copper, and end ring 1 is cast by aluminium.

Shown in figure (4) (5) (6) and (7), the centre has some blocks of copper or aluminium annular membrane 4-C by high-temperature plastic ring pad (plate) or asbestos ring pad (plate) 4-A they to be isolated, the two sides skin of this glue ring pad (plate) be around porose silicon steel ring plate 4-D, the hole is with aluminium or copper-clad envelope.

Shown in figure (8) (9) (10): aluminum skeleton 8-A is by a garden sheet and be integral with it and the less garden tube 8-B that leaves hole, garden 8-C of diameter constitutes.Embed some its silicon steel chip 8-D that circle hole 8-E arranged and axis hole 3-C is arranged in the tube of said garden on every side, be inserted in some its silicon steel ring plate 4-D that leave a circle hole 8-E on every side and hole, garden 4-B is arranged outside the tube of garden, Kong Junyong aluminium or copper-clad seal.

Shown in figure (1), with end ring 1, inner guide plate assembly 2, outer guide plate assembly 3, silicon sheet core 4 serial parts-be installed in the rotating shaft 5, promptly the cost rotor is loaded onto the Stator and electrical machine shell, promptly constitutes motor of the present invention in order.
