Embodiment Construction

[0021] In order to make the technical solution of the present invention more clearly expressed, the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as Figure 1 to Figure 5 As shown, it is a series-excited motor of the present invention, also known as a single-phase series-excited motor. The series motor includes a stator 10, a rotor assembly 30 that can rotate relative to the stator 10, two covers 40 and two carbon brushes 50, the two covers 40 are respectively fixed up and down on the stator 10, and the rotor assembly 30 wears The two carbon brushes 50 are installed on the lower cover body 40 and are in electrical contact with the rotor assembly 30 .

[0023] The stator 10 includes two opposing chip assemblies 20 in a C-shaped structure, the two chip assemblies 20 are arranged at intervals, and each chip assembly 20 is wound with a stator winding (not shown in the figure). In the present invention, the so-calle...

Abstract

A series excited machine comprises a stator, a rotor component and two covers. The two covers are fixed on the stator in an up and down mode, and the rotor component comprises an iron core, a rotation shaft arranged on the iron core in a penetrating mode, and a rotor winding wound on the iron core. The two ends of the rotation shaft are vertically arranged on the two covers respectively in a penetrating mode, the stator comprises two opposite horizontal chip assemblies, and each chip assembly is formed by vertically stacking a plurality of chips made of magnetic conductive materials; the iron core also is formed by vertically stacking a plurality of chips made of the magnetic conductive materials, the thickness of the iron core is larger than the thickness of each chip assembly, and the number of the chips on the iron core is 2-8 more than that of the chips on the chip assemblies. The iron core is thickened, the no-load speed of the motor is obviously lowered, but the load speed is not changed, in batch production, the product percent of pass is improved by 20%, and economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to a motor, more specifically to a series motor. Background technique [0002] Series excitation motor belongs to AC and DC dual-purpose motors. It can work with AC power supply or DC power supply, so it is also called universal motor or AC-DC dual-purpose motor. The stator assembly of series excitation motor is composed of magnetic core and winding The stator winding on the magnetic core is composed, and the rotor assembly is composed of iron core, rotor winding, commutator and rotating shaft. A series circuit is formed between the stator winding and the rotor winding through the brushes and the commutator. After electrification, the rotating shaft is stressed and rotates at a high speed. [0003] The no-load speed of the motor is a standard set by the manufacturing factory. In order to meet the needs of industrial production, the existing series motors have higher and higher requirements for the motor speed when the motor is lo...
