FAQ

What is an NVH test for electric motors?

An NVH test evaluates the noise, vibration, and harshness generated by an electric motor during operation. It helps manufacturers identify abnormal noise sources, vibration issues, and structural resonance, improving motor performance, reliability, and overall product quality.
What types of motors can be tested with the motor NVH tester?

The motor NVH tester is suitable for a wide range of motors, including automotive motors (EPS, brake, suspension, One-box motors), servo motors, and military-grade motors. It is mainly used for laboratory testing, R&D validation, and quality control.
What parameters can be measured by the motor NVH tester?

The tester can measure sound pressure level (SPL), vibration acceleration, FFT spectrum, 1/3 octave band analysis, order analysis, and total noise level (dB/dBA). It supports both CW and CCW testing directions and provides complete data analysis results.
