Series motor

Abstract

A series motor, comprising a stator assembly, a rotor assembly, a top cover, a base and a carbon brush, the top cover and the base are installed on the stator assembly, the rotor assembly is fixed on the top cover and the base, and the carbon brush is installed On the base, the stator assembly includes a magnetic core, two connecting sleeves mounted on the magnetic core and stator windings mounted on the connecting sleeves, the connecting sleeve includes a winding housing and a fixed core, and the winding The wire housing includes a first mounting piece, a second mounting piece and a connection block connecting the middle part of the first mounting piece and the middle part of the second mounting piece, the first mounting piece and the second mounting piece are separated by a certain distance, and the first mounting piece A winding space is formed between the second mounting piece and the stator winding is installed on the winding space. The upper and lower parts of the first mounting piece are provided with a number of cooling grooves to strengthen the heat dissipation of the stator winding; the fixed core connects the winding housing Fixed on the magnetic core, the winding of the stator winding can be completed quickly, the winding time of the stator winding can be reduced, the assembly process can be simplified, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a motor, in particular 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 current winding process of the winding of the motor stator assembly mainly adopts the direct winding method, and the single-strand enameled wire is directly wound on the magnetic core by a manipulator. Typical winding equipment is such...

AI Technical Summary

Problems solved by technology

The two processes have been widely used in production practice, but they are also limited by conditions and cannot be wound such as a small size (only about 2 mm) magnetic core notch, because the notch is small, and "twisted twist" will be produced during winding "problem, making it impossible to use the direct winding method

The coil is tightly wound on the notch of the magnetic core, and the wire cannot be embedded, so the indirect winding method cannot be used.

[0004] For the above problems, since there is no mechanized equipment that can satisfy the assembly of this type of motor windings, at present it can only be wound manually. Due to the limitations of the notch and the magnetic core itself, the labor intensity is high, not only the production cost is high, but also the efficiency is low, reducing the Business efficiency
