Abstract
The utility model relates to the motor technology field, especially to a magnetic pole used in a motor, comprising a magnetic pole body formed by superposing a plurality of silicon steel sheets. The left side center position of the magnetic pole body is outwards equipped with a bump, the right side center position of the magnetic pole body is inwards equipped with a groove corresponding to the bump, and the lower end center position of the magnetic pole body is equipped with a semi-arc-shaped notch. The magnetic pole used in the motor of the utility model employs an uneven air gap structure, enables the temperature rise to be reduced and the efficiency to be improved substantially at the same time, can effectively avoid that the running of a starter is affected due to an excess temperature, and is novel in design and strong in practicality.
Description
Technical field
The utility model relates to technical field of motors, especially a kind of motor magnetic pole.
Background technology
The development of modern industry, the starting brushless DC machine has been used in increasing place, but starter operating time one length will cause temperature to raise rapidly all the time, affects operating efficiency.
The utility model content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of motor magnetic pole, solved the problem that existing magnetic pole causes the easy excess Temperature of starter.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of motor magnetic pole, comprise the magnetic pole bodies that a plurality of silicon steel sheet stacks form, the center, left side of described magnetic pole bodies is to being outside equipped with a projection, the center, right side of described magnetic pole bodies inwardly offers the groove corresponding with described projection, and center, described magnetic pole bodies lower end is provided with the semicircular arc recess.
Further, described magnetic pole bodies is sector structure.
Further, described magnetic pole bodies upper end radian is less than the diameter of stator bore radian.
The beneficial effects of the utility model are, a kind of motor magnetic pole of the present utility model adopts the non-uniform gap structure, can greatly raise the efficiency when reducing temperature rise, can effectively avoid the starter excess Temperature to affect its operation, and modern design is practical.
