[0002] Permanent magnet synchronous motors are widely used in industries, household appliances and other fields due to their high efficiency and energy saving. During the operation of the motor, vibrations and external disturbances are inevitably generated, which not only affect the operation accuracy and stability of the motor, but also may cause loosening and damage of the motor components, thereby shortening the service life of the motor.

[0003] Most of the existing motor supports have fixed structures, and the resistance to vibrations and external disturbances generated during the operation of the motor is limited, and the adaptive adjustment cannot be made according to the actual vibrations and disturbances. For example, some supports only use simple rubber pads for damping, and when the load of the motor changes or the operating conditions change, the damping effect of the rubber pads will be greatly reduced, and the transmission of vibrations cannot be effectively inhibited, thereby affecting the normal operation and working performance of the motor. Therefore, the permanent magnet synchronous motor device with an adaptive anti-interference support is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

[0022] The top outer wall of the base 22 is fixedly connected with a plurality of fixing seats 8, and every two fixing seats 8 are located at the two ends of the sliding rail 3, and a damping rod 11 is fixedly arranged between the sliding block 4 and the fixing seat 8, so that the damping rod 11 provides damping force when the sliding block 4 moves relative to the fixing seat 8, consumes vibration energy and effectively suppresses the vibration of the motor.

[0023] Further, the outer walls of every two lower connecting seats 5 away from each other are fixedly connected with a sliding rod 9, and the end, away from the lower connecting seat 5, of the sliding rod 9 penetrates the fixing seat 8.
