Abstract

The invention discloses a hybrid stepping motor which contains a rotor, a stator and windings. The rotor is arranged in the stator, the stator is provided with multiple magnetic poles, the windings are arranged on the magnetic poles, and permanent magnet steel is embedded into the stator. According to the hybrid stepping motor, the no-load flux linkage and the no-load back electromotive force bothpresent sine rule changing, besides that the advantages of being high in precision and torque and the like are achieved, the structure of the rotor is greatly simplified, the strength and the stability of the rotor are enhanced, therefore, the reliability of the hybrid stepping motor is improved, and the application working condition and the application range of the motor are expanded.

Description

technical field [0001] The invention relates to the field of hybrid stepping motors, and in particular relates to the body design of the hybrid stepping motor. Background technique [0002] Stepper motors have been widely used in various fields of production and life due to their open-loop control, good positioning accuracy, low price, easy start and stop, forward and reverse rotation, no accumulated error, and self-locking function. Especially the hybrid stepper motor has good application prospects due to its advantages of high resolution, large torque and stable temperature characteristics. [0003] The traditional hybrid stepper motor is divided into rotor, stator, magnetic steel, winding and other parts. The magnetic steel is placed in the rotor, and the winding is wound in the stator slot. It has axial excitation and radial excitation sources. If there is no magnet steel on the rotor, the motor will not generate torque if it is only energized in the control winding of ...
