Description

Technical Field

[0001] The utility model relates to the technical field of motor noise reduction, in particular to a noise reduction structure for a servo motor module. Background Art

[0002] At present, in traditional series-excited brushed motors, very sharp airflow noise will be caused due to the vibration and high-speed rotation of the motor during use. As the size of the motor itself becomes more and more compact, the existing motors will form extremely fast vortex airflow in a very small internal space, which is the origin of the sharp noise.

[0003] The existing noise reduction method is usually to set a sealed soundproof shell outside the motor to reduce the noise generated inside the motor. However, this noise reduction method will cause the heat of the motor to not evaporate effectively. Therefore, how to reduce the noise of the motor while ensuring that the heat dissipation of the motor is not affected becomes a problem. To this end, a noise reduction structure for a servo motor module is proposed. Utility Model Content
