A high-quality micro electric hoist runs smoothly and quietly, and may produce some subtle sounds, but they are all normal sounds generated by the interaction of components. If the noise of the micro electric hoist is obvious and harsh, then there is a certain problem. What is the reason for the noise of the micro electric hoist?

① Motor noise: The motor of a micro electric hoist generates vibration and noise during operation. The operation of the motor can cause mechanical vibration, which in turn produces sound. The use of low-quality motors or poor sound insulation design may increase the noise level.

② Gear transmission noise: Micro electric hoists usually use a gear system to transmit power, converting the high-speed rotation of the motor into the lifting motion of the lifting machinery. The gears produce noise during the meshing process, especially when the load is heavy or the gears are worn out.

③ Mechanical structure noise: The mechanical structure of a crane, including brackets, running tracks, etc., may also produce noise due to vibration during use.

④ Control system noise: Electronic components in the control system, such as relays, frequency converters, etc., may also produce noise due to changes in current and voltage

These are the common causes of noise in micro electric hoists, and further analysis is needed to determine the specific reasons. If this situation occurs during the use of your micro electric hoist, it is recommended to stop running, undergo testing and maintenance, and then continue using it to prevent the degree of malfunction of the micro electric hoist from increasing and becoming irreparable.
