Embodiment Construction
[0028] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0029] This example is 3.26 inches Diameter 12V / 24V 500W permanent magnet DC pump motor, see the general structure of the motor figure 1 : Including casing 2, magnetic steel 3, brush holder plate 1 and armature punching plate 4. It is characterized in that the design scheme of the components is as follows:
[0030] Insulation material of the motor: H-class (185°C) insulation is used, and insulation material with high heat resistance level is used to enable the motor to withstand high temperature rise and further improve its working system.
[0031] Chassis such as figure 2 : 4mm thick 10# steel pipe is used, the thickness of the yoke is increased by 53%, the magnetic permeability of the material is increased, the magnetic permeability of the material is increased by 1 / 3, the magnetic density of the stator is reduced, and the heating of the stator is reduced....
