Amid the rapid development of electric vehicles (EVs), the motor, as one of the core components, plays a critical role in determining the overall performance and safety of the vehicle. However, during operation, motors often face various potential failures, including mechanical faults such as stator core damage, rotor core damage, bearing failure, and shaft deformation, as well as electrical faults like stator winding and rotor winding issues. These malfunctions not only degrade motor performance but may also lead to vehicle breakdowns, increased maintenance costs, and even serious safety incidents.

Before being assembled into the vehicle, motors must undergo comprehensive performance testing, with vibration levels at different speeds and power outputs being one of the key indicators. Vibration monitoring not only reflects the operational status of the motor but also helps detect potential faults in advance. However, traditional vibration monitoring typically requires installing separate sensors for each of the three axes (X, Y, Z), which complicates installation and raises costs. Now, KEHAO has introduced its next-generation KH-ZD series triaxial vibration sensor, providing an integrated solution for EV motor vibration monitoring.
