Abstract

This utility model is the rotor punching of a kind of high efficiency motor, including lamellar body, the uniform magnet steel groove being provided for fixing magnet steel on lamellar body, it is provided with magnet steel card pilot trench in the both sides of each magnet steel groove, it is provided with long strip type air vent between two adjacent magnet steel grooves, being additionally provided with S type air vent in the side of each long strip type air vent, lamellar body is eight fan-shaped entirety constituted.This utility model simple in construction, reasonable in design, novel, air vent has not only acted as thermolysis and also has alleviated the weight of punching, reduces the impact of inertia.

Description

A kind of rotor punching of high efficiency motor
Technical field
This utility model belongs to technical field of motors, particularly relates to the rotor punching of a kind of high efficiency motor.
Background technology
Present motor rotor punching sheet is usually cast-in aluminum squirrel cage rotor, and four to pole, stator 48 groove, rotor 55 groove, power supply frequency Rate is 50Hz/60Hz, and motor speed is 700rpm/825rpm, electric machine iron core length 270mm, not only puts into big, and efficiency Low, do not reach the effect of energy-conserving and environment-protective, and present punching weight is greatly, namely can produce certain inertia and weight Measure heavier, and ventilation effect is poor.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of rotor punching, and this punching is lightweight and has one Fixed ventilation effect, and energy-efficient.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
This utility model is the rotor punching of a kind of high efficiency motor, and including lamellar body, on lamellar body, uniform being provided for is fixed The magnet steel groove of magnet steel, is provided with magnet steel card pilot trench in the both sides of each magnet steel groove, arranges between two adjacent magnet steel grooves Having long strip type air vent, be additionally provided with S type air vent in the side of each long strip type air vent, lamellar body is eight fan-shaped compositions One entirety.
Further improvement of the utility model is: the angle that the extended line of the centrage of two adjacent magnet steel grooves is formed It it is 45 degree.
Further improvement of the utility model is: each magnet steel groove is the structure that width one end, one end is narrow.
Further improvement of the utility model is: described rotor punching is four to pole, eight magnet steel.
The beneficial effects of the utility model are: rotor punching of the present utility model and current asynchronous motor universal and stator Winding is also identical with asynchronous machine, but rotor of the present utility model is the p-m rotor with 8 Nd-Fe-B magnet steels, and permanent magnetism turns Son just forms synchronous motor with the stator collocation of three-phase windings, and its efficiency is higher than asynchronous machine, energy-conservation, the motor of same power, Electric machine iron core length 160mm, saves material, and subtracts and can lower consumption, and adds long strip type and S type on punching lamellar body and lead to Air holes, long strip type and S type air vent with the use of, add the performance of ventilating of rotor so that permanent magnet heat radiation obtain one Fixed improvement.
This utility model simple in construction, reasonable in design, novel, air vent has not only acted as thermolysis and also has alleviated The weight of punching, reduces the impact of inertia.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with drawings and Examples, this utility model is done further Describing in detail, this embodiment is only used for explaining this utility model, does not constitute protection domain of the present utility model and limits.
As shown in Fig. 1, this utility model is the rotor punching of a kind of high efficiency motor, and including lamellar body 1, described lamellar body 1 is eight The individual fan-shaped entirety constituted, say, that the periphery of lamellar body is not circular, but has half radian, at described On body 1, the uniform magnet steel groove 2 being provided for fixing magnet steel, is provided with magnet steel card pilot trench in the both sides of each described magnet steel groove 2 3, each magnet steel groove 2 is round and smooth mountain font structure with adjacent two magnet steel card pilot trench 3, two adjacent magnet steel grooves 2 it Between be provided with long strip type air vent 4, be additionally provided with S type air vent 5, long strip type in the side of each described long strip type air vent 4 And the setting of S type air vent not only reduces the weight of punching, moreover it is possible to play good draught effect so that permanent magnet dispels the heat Improved, and, the lightweight inertia the most just decreasing punching, the prolongation of the centrage of two adjacent magnet steel grooves 2 is linear The angle become is 45 degree, and each described magnet steel groove 2 is the structure that width one end, one end is narrow, and described rotor punching is four to pole, eight Sheet magnet steel.
Rotor punching of the present utility model is also identical with asynchronous machine with current asynchronous motor universal and stator winding, but Be rotor of the present utility model be the p-m rotor with 8 Nd-Fe-B magnet steels, the stator collocation of p-m rotor and three-phase windings Just forming synchronous motor, its efficiency is higher than asynchronous machine, energy-conservation, the motor of same power, electric machine iron core length 160mm, saves Raw material, subtracts and can lower consumption, and adds long strip type and S type air vent on punching lamellar body, and long strip type and S type ventilate Hole with the use of, add the performance of ventilating of rotor so that permanent magnet heat radiation be improved.
