Problems solved by technology

However, the biggest disadvantage of stepping motors is that the working speed cannot be increased. If the speed of the motor is high, the output torque of the motor will drop quickly, the motor will lose its step, and finally the motor will stop.

Abstract

The invention relates to the technical field of stepping motors, in particular to an eight-pole stepping motor with a large stepping angle being 3 degrees. The eight-pole stepping motor with the large stepping angle being 3 degrees consists of a stator punching and a rotor punching, the stator punching consists of eight stator poles and a stator yoke, wherein the eight stator poles are distributed uniformly, and three stator teeth are arranged on each pole of a stator, so that 24 stator teeth are arranged; and the rotor punching consists of 30 rotor teeth and a rotor yoke, and the 30 rotor teeth are distributed uniformly, so that the stepping motor with the large stepping angle being 3 degrees is formed. The eight-pole stepping motor with the large stepping angle being 3 degrees has the advantages that the design is reasonable, the structure is simple, the work stepping frequency property is good, the effective running efficiency is high, the load rotating speed of the motor is increased greatly, the loss when the motor is in high-frequency running is small, the efficiency is high, the work is stable, the work temperature rising is low and the like and is novel in structure and high in performance.

Description

technical field [0001] The invention relates to a stepping motor, in particular to a stepping motor with 8 poles and 3° large step angle. Background technique [0002] At present, stepper motors are widely used in industries requiring high precision such as automatic control, textile machinery, medical equipment, and machining. Due to their high machining accuracy and small step angle, stepper motors are high-precision motors. Stepper motor is an open-loop high-precision positioning torque, which is widely used. However, the biggest disadvantage of stepping motors is that the working speed cannot be increased. If the speed of the motor is high, the output torque of the motor will drop quickly, the motor will lose its step, and finally the motor will stop. [0003] The step angle of the stepper motor is generated by the stator teeth and rotor teeth of the stepper motor under the action of different pulse currents passing through the coils of the stator. Generally, the step ...
