Warranty Information
The warranty is 12 months after commissioning, but no later than 18 months from shipment.
The AMXE160 motor is designed for heavy electrical vehicle applications, including traction, generator, or auxiliary roles. It's actively liquid-cooled and optimized for high efficiency and performance. Key features include a 3-phase permanent magnet synchronous design, inverter adaptation, Class H insulation, and temperature sensors. The operating ambient temperature range is -20°C to +40°C. Proper installation, maintenance, and adherence to operating conditions are crucial for safety and longevity. Failure mode operation is possible for short durations under specific conditions, but prolonged operation can cause damage.
Troubleshooting and error codes
| Mechanical failures | Possible cause of failure | Corrective action |
|---|---|---|
| Motor is vibrating and generating abnormal noise. | Damage bearing. | Please contact ABB for further instructions. |
| Motor starts with scraping noise. | Foreign particles in the air gap. | Please contact ABB for further instructions. |
| Motor starts with abnormal permanent scraping noise. | Rotor and stator touch each other in the air gap. | Please contact ABB for further instructions. |
| Motor is abnormally hot also at no load. | Liquid cooling system is out of order. | Check liquid cooling system's functionality. |
| High vibrations at run out. | Too high residual unbalance. | Please contact ABB for further instructions. |
| Bearing failure during normal operation. | Misaligned total driving axle system. | Check the alignment, make corrections, and contact ABB for further instructions. |
| Motor does not start at load, normal magnetic noise. | Load torque too high. | Uncouple the motor and test it separately at no load, compare the results with other motors tested at no load. |
| Shaft torque disappear. | Loose coupling on the shaft. | Take the motor out of them chassis. Investigate the shaft and coupling dimensions. Replace defect component. |
| Motor does not start, no current, no noise. | Interruption on at least two phases. (Open circuit) | Measure the resistance between the phases to investigate if the stator is damaged. If the stator is damaged, please contact ABB for further instructions. |
| Motor starts with a continuous hum. | Interruption on one phase. (Open circuit) | Check the incoming cables. Measure the resistance for each phase. If the stator is damaged, please contact ABB for further instructions. |
| Motor starts with the wrong direction of rotation. | Wrong phase sequence on the incoming cables. | Check the phase sequence for the incoming cables. |
| Motor generates an abnormally high noise level. | Can be caused by mechanical or electrical interference. | Switch off the electrical feed. If the noise remains, it is a mechanical fault. If not, it is an electrical fault. |
| Motor current is abnormally high. | Fault in the stator winding. | Measure the winding resistance between the stator terminals. |
| Motor has different phase currents and gets high temperatures. | Asymmetrical feeding. | Check the similarity of the phase voltage on the incoming cables. |
| Motor gets an abnormally high phase current and high temperature, also at no load. | Wrong incoming voltage level. | Correct the incoming voltage levels. |
| Smoke appears from the motor. | Fire after flash-over or short circuit in a part of the stator winding. | Disconnect the motor, remove it. Rewinding is most likely necessary, please contact ABB for further instructions. |
| Motor current is abnormally high. | Demagnetized rotor magnets. | It's possible to continue the operation with reduced performance. The rotor should be replaced to obtain full performance, please contact ABB for further instructions. |
| Insulation resistance below 10 ΜΩ. | The stator winding is too damp. | Check for any defect components (covers, seal etc.). The stator winding must be oven dried, please contact ABB for further instructions. |
