Abstract
The utility model discloses an induction permanent-magnet stepping motor. The utility model is provided with a stator, a rotor, a front end cap, a rear end cover and a rotation shaft. The rotor iron core of the rotor is provided with 50 rotor teeth. The stator is provided with 8 large poles. Each large pole is wound with a concentrated winding. Each large pole is provided with 6 stator teeth. The included angle of the central lines of the adjacent stator teeth is 6.8 DEG-7.0 DEG. Under the condition of the unchanged size of the external shape, the utility model improves the output torque of 30-50%.
Description
The utility model relates to a kind of stepping motor.
The typical structure of existing inductor type permanent-magnet stepper motor is, stator is divided into 8 big utmost points, each is big to have 5 stator tooths on extremely, 50 rotor tooths are arranged on the rotor, the center line angle of adjacent stators tooth and rotor tooth equates, be 7.2 °, there is the little shortcoming of output torque in the stepping motor of this structure.
It is a kind of under the situation that does not increase the motor overall dimensions that the purpose of this utility model is to provide, and output torque can improve 30～50% inductor type permanent-magnet stepper motor.
In order to achieve the above object, the technical solution of the utility model is, a kind of inductor type permanent-magnet stepper motor, have stator, rotor, front end housing, rear end cap and rotating shaft, the rotor core of rotor is provided with 50 rotor tooths, and stator has 8 big utmost points, each big extremely going up around concentrated winding, each is big extremely to be provided with 6 stator tooths, and the center line angle of adjacent stators between cog is 6.8 °～7.0 °.
In order further to achieve the above object, and improve the step angle precision of stepping motor, the center line angle of adjacent stators between cog can be at 6.875 °～6.975 °.
After adopting said structure, extremely be provided with 6 stator tooths because each of stepping motor stator is big, the quantity of stator tooth has increased, and the center line angle of adjacent stators between cog is 6.8～7.0 ° simultaneously, and this increases the motor output torque, can improve 30～50%; Stator tooth owing to each big utmost point has only increased by one again, the corresponding increase of the internal diameter of stator and rotor diameter, and the motor overall dimensions then can remain unchanged.
Below in conjunction with drawings and Examples the utility model is done explanation in further detail.
