旋转方向不符合要求时，调整电源相序即可； 3. When the rotation direction of the vibration motor does not meet the requirements, adjust the power phase sequence;
4. The motor should ensure that the lubricating oil is good. The motor equipped with a grease nipple starts to operate, and is replenished with 3 # lithium-based grease (ZL-3) every two weeks or so, and then refilled every 600 hours after operation. Refueling amount is controlled at 15-20g each time. (When using sealed bearings, the motor is not equipped with a grease nipple);
5. After the machine has been running for 1500 hours, the bearing should be inspected, and it should be replaced immediately if there is serious damage; 6. When the machine is parked for a long time and used again, the insulation resistance should be measured with a 500 volt megohm meter. Should be greater than 0.5 megohms.
