Problems solved by technology

In practice, since the reluctance of the silicon steel sheet used in the armature is much smaller than that of air, the existence of the iron core teeth makes the distribution of the magnetic force lines in the air gap of the motor uneven, which makes the electromagnetic force on the motor unbalanced when the motor is running, resulting in The motor vibrates and generates noise

Embodiment Construction

[0012] Such as figure 1 As shown, after the head of the iron core tooth T-shaped part 2 of the silicon steel sheet 3 of the armature has a groove 1, several silicon steel sheets 3 are laminated to form the armature iron core 4, as figure 2 shown.

[0013] Namely, in the armature core of the rotating electrical machine of the present invention, the iron core 4 with silicon steel sheets 3 laminated has a plurality of T-shaped iron core teeth, and a groove 1 is formed on the head of the T-shaped iron core teeth along the axis of the armature. The iron core 4 is formed by stacking a number of silicon steel sheets 3, each silicon steel sheet 3 has a plurality of T-shaped parts 2, and each T-shaped part 2 has a notch at the head, so that the head of the T-shaped iron core tooth is along the axis of the armature. direction to form a groove 1.

[0014] The principle of the technical solution of the present invention is, as Figure 4 As shown, because the motor iron core has T-shap...

Abstract

The invention discloses an armature core for a rotating motor. The core is provided with a plurality of T-shaped core teeth, and the head of each T-shaped core tooth is provided with a groove along the axis direction of the armature. The core is formed by laminating a plurality of silicon-steel sheets, each silicon-steel sheet is provided with a plurality of T-shaped parts, and the head of each T-shaped part is provided with a notch so that the head of the T-shaped core tooth forms a groove along the axis direction of the armature. By applying the armature motor provided by the invention to vehicle-mounted device control, the operation of the motor becomes more stable, vibration is smaller, and noise is lower.

Description

technical field [0001] The invention belongs to the technical field of rotating electrical machines, in particular to an armature iron core for rotating electrical machines. Background technique [0002] In the prior art, the magnetic pole T-shaped part of the iron core of the armature of the rotating electrical machine is formed by stacking a certain number of plate-shaped parts. The T-shaped parts of the magnetic poles are evenly distributed on the circumference of the plate-shaped part to form iron core teeth, and the T-shaped heads of the iron core teeth are smooth curves. In practice, since the reluctance of the silicon steel sheet used in the armature is much smaller than that of air, the existence of the iron core teeth makes the distribution of the magnetic force lines in the air gap of the motor uneven, which makes the electromagnetic force on the motor unbalanced when the motor is running, resulting in The motor vibrates and generates noise.
