Abstract

The utility model relates to a motor rotor strip, belonging to a component in the motor. The strip is provided with concave or convex cone tank, and the upper ends of every contiguous concave or convex cone tanks are punched with trapezoid-shaped rotor tank. The utility model has the advantages of simple structure and simple processing, improving the utilization of raw material and reducing the cost of the motor.

Description

Motor rotor strip
The utility model relates to a kind of motor rotor punching slice, belongs to parts in the motor.
Motor rotor is made of the rotor punching that silicon steel sheet material is made, and rotor is the indispensable parts of motor.Rotor punching in the past is to utilize square or the circular rotor punching of rectangle silicon steel sheet punching out, and the utilance of material only is 50%.Therefore expense is big, the cost height.
The utility model purpose provides a kind of motor rotor punching slice, and it reasonably utilizes raw material, improves stock utilization, and easily manufactured, and cost is low.
The utility model mainly is uniform matrix or the tapered groove of convex made at vertical bar type silicon steel sheet, is washed into trapezoidal rotor between the upper end of every adjacent conical groove or tongue.
Description of drawings:
Fig. 1--the utility model master TV structure figure;
Fig. 2--the utility model launches schematic diagram.
In conjunction with the accompanying drawings the utility model structure is specified.
By Fig. 1,2, this motor rotor punching slice is to be the uniform isosceles triangle broken line that is shaped on of rectangle silicon steel sheet with the vertical bar type, and punching press system matrix or the tapered groove of convex (2), make its vertical bar type silicon steel sheet become round rotor punching (3), and, promptly constitute motor rotor punching slice at the upper end punching out of every adjacent tapered (2) rotor (1) in echelon.
The utility model advantage, it is simple in structure, and is easy to process, greatly improves the utilization rate of silicon steel sheet. Through test determination, this rotor punching is made motor rotor, and electromagnetic property does not have impact, and motor performance does not have impact, and the silicon steel sheet material utilization rate is brought up to more than 85% reduction raw materials consumption and motor cost.

Claims (1)

1, a kind of motor rotor punching slice is characterized in that being shaped in the punching the tapered groove of matrix or convex, and the upper end of every adjacent grooves or tongue dashes trapezoidal rotor.
