YE3 Motor Installation Specification And Operation Steps

1. Preparation before installation

   Environmental requirements: Choose a dry, well-ventilated site with no corrosive gases, make sure there is enough space for heat dissipation, and avoid high temperature or humid environment to affect the life of the motor38.

   Tools and accessories: Prepare level, wrenches, bolts, anti-vibration shims (e.g., hard rubber or wooden boards), and check the matching of the motor nameplate parameters (voltage and power) with the load38.

2. Base and Motor Installation

   Chassis fabrication:

       The size of the base needs to be 150mm larger than the motor chassis, the height is usually higher than the ground 150mm, and it is fixed by cement pouring or groove rail 3.

       Ground bolts need to be pre-buried with slots for reinforcement to ensure a close fit with the base3.

   Motor positioning:

       Small motors are handled manually, large equipment is lifted by crane, and anti-vibration pads are added between the base and the motor to reduce vibration38.

       Use the level meter to correct the longitudinal and transverse level, use the steel plate to adjust when the deviation is more than 0.5mm3.

3. Drive installation

   Belt drive:

       Two belt pulleys should be kept parallel and aligned with the axis, and the distance between the triangular belt pulleys should not be changed due to the anti-vibration pads being too thick 3.

       Regularly check the belt tension to avoid slipping or over-tightening resulting in loss of efficiency 8.

   Coupling alignment: shaft center deviation needs to be less than 0.05mm to prevent bearing wear and vibration overrun36.

4. Electrical connection and commissioning

   Wiring specification: Connect the power cord according to the junction box marking, ensure reliable grounding (grounding resistance ≤ 4Ω) to avoid the risk of leakage78.

   Trial run:

       Start with no load to check whether the steering is correct, gradually load to the rated load, monitor the current and temperature rise (not exceeding the B insulation limit of 80K) 78.

       Immediate shutdown in case of abnormal noise or vibration, troubleshoot bearing wear or mounting deviation
