Abstract

The invention discloses a novel DC motor commutator integrating an EMC circuit, wherein the EMC circuit comprises three parts, namely a positive pole working armature module, a negative pole working armature module and a comprehensive filtering module. The positive pole working armature module is connected with the positive pole of a motor M and is connected with the positive pole of an input power supply; and the negative pole working armature module is connected with the negative pole of the motor commutator M and is connected with the negative pole of the input power supply; and the comprehensive filtering module is arranged between the positive pole and the negative pole of the input power supply. The motor can be directly installed inside the motor and assembled with the motor to forma complete part. The motor is arranged inside the equipment as a part, and all the components are integrated together through a comprehensive application layout. The circuit commutator can be directly used for meeting the test requirements of electromagnetic compatibility. Therefore the product design space can be reduced to the maximum extent, the product structure is optimized, the assembly processes are reduced, the assembly efficiency is improved, and the labor and material cost is saved.

Description

technical field [0001] The invention relates to the technical field of DC motors, in particular to a DC motor commutator that can improve EMC (Electromagnetic Compatibility), and can be used for commercial or similar electrical appliances that need to meet the requirements of the Electromagnetic Compatibility Directive. Background technique [0002] EMC refers to the ability of a device or system to operate in compliance with the requirements in its electromagnetic environment without causing unbearable electromagnetic interference to any equipment in its environment. It mainly includes two requirements. One is that the equipment will affect the environment during normal operation. The electromagnetic interference generated cannot exceed a certain limit. Second, the equipment has a certain degree of anti-interference ability to the electromagnetic interference in the environment, that is, electromagnetic sensitivity. At present, in the general product design process, the bas...
