Problems solved by technology

[0002] The current commonly used brushed DC motor requires a large amount of current, so it is not suitable for the production of high-power DC motors. The main reason for the high energy consumption of DC motors is that the use of the rotor coils is not perfect, because the current motor rotor coils are connected in series. , the magnetic fields generated by adjacent working coils cancel each other out partly, resulting in undue loss of current

Abstract

The disclosed DC motor includes following parts: chassis, stator installed inside chassis, rotor core setup at shaft, armature winding on core for generating magnetic beam, and converter installed on the shaft for supplying power to armature windings. There are at least more than two pairs of magnetic poles on the stator. Number of winding on armature is twice of number of stator pole. Multiple windings on armature are separated into two groups of winding. In each group, adjacent windings generate same magnetic pole so as to increase density of magnetic flux, or avoid cancel of magnetic flux. Thus, work efficiency of DC motor is increased. Cascaded windings in each group are connected to converter installed on shaft.

Description

technical field [0001] The invention relates to a direct current motor, in particular to a multi-magnetic pole direct current motor. Background technique [0002] The current commonly used brushed DC motor requires a large amount of current, so it is not suitable for the production of high-power DC motors. The main reason for the high energy consumption of DC motors is that the use of the rotor coils is not perfect, because the current motor rotor coils are connected in series. , the magnetic fields generated by adjacent working coils cancel each other out partly, resulting in undue loss of current. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-magnetic pole DC motor which improves the utilization rate of current and reduces energy consumption. [0004] In order to achieve the above object, the technical solution of the present invention is: the multi-pole DC motor includes a casing, including a stator...
