Abstract

The invention relates to the field of a direct current motor, and specifically to a commutating pole structure. The commutating pole comprises a commutating pole coil, a flux-insulation sleeve, a commutating pole iron core and a spring supporting plate; the commutating pole iron core is fixed on the spring supporting plate; the commutating pole iron core is sleeved with the flux-insulation sleeve; and the flux-insulation sleeve is sleeved with the commutating pole iron core. The commutating pole structure provided by the invention is easy to assemble, convenient to operate, labor-hour-saving, quite high in mechanical strength and insulating property, and capable of effectively solving the problems of high flux leakage under a dynamic state and high probability of collapse under high current impact of the commutating pole.

Description

technical field [0001] The invention relates to the field of direct current motors, in particular to a commutation pole structure of a direct current motor. Background technique [0002] At present, domestic DC motors are generally composed of commutating pole cores and commutating pole coils. The commutating poles of this structure have problems such as a large proportion of leakage flux under dynamic conditions, poor dynamic response, and easy collapse under high current impact. Contents of the invention [0003] The invention provides a commutation pole structure, which is simple in structure and ingenious in design, and solves the problem that the commutation pole is prone to collapse under dynamic magnetic flux leakage and high current impact. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A reversing pole structure, including a reversing pole coil, a magnetic isolation sleeve, a reversing pole iron core an...
