Abstract
The utility model relates to a motor rotor stamped piece, in particular to an optical shaft rotor stamped piece for high-speed motors. The high-speed motor rotor stamped piece comprises a stamped piece body (1), wherein a shaft hole (2) is arranged in the centre of the stamped piece body (1); a wire embedded slot (3) is arranged at an outer edge of the stamped piece body (1); an air through hole (4) in the shape of an isosceles trapezoid is arranged between the shaft hole (2) on the stamped piece body (1) and the wire embedded slot (3); and a central line of the air through hole (4) in the shape of the isosceles trapezoid passes through the circle centre of the stamped piece body (1). In the high-speed motor rotor stamped piece, the air through hole adopts the design of the trapezoid, a rotor tooth part and a yoke magnetic path are greatly optimized, the electric performance of the motor is increased, the ventilation area of the rotor is greatly improved, and the temperature rise of the winding of the rotor is effectively reduced.
Description
Technical field
The utility model relates to a kind of motor rotor punching sheet, particularly relates to a kind of optical axis rotor punching that is applicable to high-speed electric expreess locomotive.
Background technology
Present motor rotor punching chip architecture is different, and its motor that is suitable for is also inequality.But for high-speed electric expreess locomotive, rotating speed is fast because it has, temperature rise, and therefore the rotor for motor internal has proposed higher heat radiation requirement.And existing rotor punching design does not propose special corrective measure to this; Conventional rotors punching ventilation hole adopts the circular hole design; Be helpless to or be unfavorable for the lifting of motor electric property; Also have some rotor punchings just to utilize the additional function of certain perforate of existing structure to ventilate, ventilation effect is relatively poor.
The utility model content
The utility model is not enough to prior art, proposes a kind of high speed rotor of motor punching, and ventilation hole adopts trapezoidal design; Rotor tooth portion, yoke portion magnetic circuit have not only been optimized greatly; Promote the motor electric property, and improved the rotor ventilation area, reduced the rotor winding temperature rise effectively.
The technical scheme that the utility model adopted:
A kind of high speed rotor of motor punching; Comprise punching body (1); Said punching body (1) center is provided with axis hole (2); Punching body (1) outer rim is provided with line embedding groove (3), between axis hole (2) on the said punching body (1) and line embedding groove (3), is provided with the ventilation hole (4) of isosceles-trapezium-shaped, and the ventilation hole of said isosceles-trapezium-shaped (4) center line is through the center of circle of punching body (1).
Described high speed rotor of motor punching, the ventilation hole of said isosceles-trapezium-shaped (4) closes on the width of width less than the upper base that closes on line embedding groove (3) of going to the bottom of axis hole.
Described high speed rotor of motor punching, line embedding groove (3) adopts No. 15 rotor grooveds of distortion; The rotor outside is an orthodrome, and bottom inside is little circular arc, and both sides are that straight line seamlessly transits; Perhaps, the evagination hole that one is communicated with is set on the orthodrome top, the outside of line embedding groove (3).
Described high speed rotor of motor punching, the ventilation hole of isosceles-trapezium-shaped (4) is 15～30, the center of circle that centers on punching body (1) evenly distributes.
The useful good effect of the utility model:
1, the utility model high speed rotor of motor punching, ventilation hole adopts trapezoidal design, compares with the circular ventilation hole of tradition, has optimized rotor tooth portion, yoke portion magnetic circuit greatly, has promoted the motor electric property.
2, trapezoidal design is adopted in the utility model high speed rotor of motor punching, ventilation hole, has improved the rotor ventilation area greatly, has improved rotor winding heat dissipation environment, has effectively reduced winding temperature rise, has improved the reliable ability of motor, has prolonged motor useful life.
3, the utility model high speed rotor of motor punching; Ventilation hole adopts 15～30 trapezoidal holes evenly to distribute along the center of circle of punching body; Line embedding groove adopts No. 15 rotor grooveds of distortion; When the distortion grooved was taken into account electromagnetic performance, the punching process character that spacing is good effectively reduced the punching burr and prolongs die life.Comparing with traditional punching in the past, show unique characteristics, is the innovation of high-speed electric expreess locomotive punching design.
