Description

A low-vibration, high-efficiency and energy-saving motor

Technical Field

The invention relates to the technical field of high-efficiency energy-saving motors, and in particular to a low-vibration high-efficiency energy-saving motor.

Background Art

High-efficiency energy-saving motors refer to general standard motors with high efficiency. High-efficiency energy-saving motors adopt new motor designs, new processes and new materials. They improve output efficiency by reducing the loss of electromagnetic energy, thermal energy and mechanical energy. Compared with standard motors, the energy-saving effect of using high-efficiency motors is very obvious. Under normal circumstances, the efficiency can be increased by an average of 4%.

Traditional motors are often accompanied by large vibrations during operation, which not only affects the service life and reliability of the motor, but may also have adverse effects on surrounding equipment and the environment. The vibration problem mainly comes from the combined effects of the electromagnetic force inside the motor, insufficient structural strength, and external environmental factors (such as foundation vibration, wind load, etc.). In order to improve the stability of the motor during operation, damping blocks are installed at the bottom of the high-efficiency energy-saving motor to reduce the vibration of the motor during operation. However, the damping blocks made of rubber are prone to aging, and long-term mechanical extrusion and stretching will cause the shape and performance of the rubber support to change, which cannot effectively reduce the shock of the high-efficiency energy-saving motor. It will still cause large vibrations in the high-efficiency energy-saving motor during operation, and when the damping block is damaged or deformed, the high-efficiency energy-saving motor needs to be disassembled for replacement, which requires long-term shutdown and disassembly, resulting in increased maintenance costs.
