Problems solved by technology

However, the manufacture of the inclined groove iron core is cumbersome, and it is not convenient for stacking riveting and subsequent manufacturing, which makes the manufacturing process of the entire motor more complicated, and the cost is higher than that of the straight groove motor.

Abstract

The invention relates to a motor and provides a motor capable of reducing motor manufacturing cost. The motor comprises a rotor and a stator, wherein the rotor comprises two circular arc magnetic shoes; the two magnetic shoes are cylindrical after installation and the rotor is installed in the magnetic shoes; a rotor groove of the rotor is parallel with an axis of the rotor; and an included angle beteween a magnetic shoe end face of the magnetic shoe and magnetic shoe axis is larger than or equal to 3 degrees and is less than or equal to 15 degrees. The magnetic shoe end face is arranged into a certain inclination, at the same time, a gap between the magnetic shoes is inclined, thus the space formed between the magnetic shoes and a straight flute iron core is the same as a space formed between an inclined iron core and a common magnetic shoe, so that the rotor groove passes through the space between magnetic shoes, and torque pulsation caused by tooth harmonic field is weakened or eliminated. The invention has the advantages that the manufacturing of the magnetic shoes is simple, has low fault rate relatively, thus the cost of the whole motor is reduced, and the manufacturing efficiency of the whole motor is improved.

Description

technical field [0001] The invention relates to an electric machine. In addition, the invention also relates to a magnetic tile. Background technique [0002] In the slotted armature permanent magnet DC motor, due to the existence of cogging, the air gap permeability between the permanent magnet and the opposite armature surface is not uniform, thus generating reluctance torque, that is, the rotor slot rotates to When the magnetic tile gap occurs, the rotor slot is exactly opposite to the magnetic tile gap, causing a sudden change in the magnetic field received by the rotor and causing the pulsation of the motor output torque. This adverse effect is called the cogging effect. In order to reduce the deficiencies caused by the cogging effect of the motor in the design and manufacture of the motor, the groove of the motor rotor core is generally made into a chute, and the rotor core is matched with the ordinary magnetic tile. Among them, the chute gradually passes through the...
