Motor Surge Measurement with High Definition Oscilloscope

Motor Surge Measurement with High Definition Oscilloscope

Issue:

The high-speed switching voltage of the inverter generates a high-voltage surge on the motor side, which can cause dielectric breakdown of the windings. Therefore, checking the motor surge voltage is an essential process in motor development and manufacturing. In recent years, as the efficiency of inverters using high-speed devices such as SiC has improved, the voltage and speed of motor surges have increased and the phenomenon has become more complex, requiring more accurate waveform analysis.

Solution:

The DLM5000HD equipped with a 12-bit ADC can simultaneously capture 8 channels of surges and related waveforms with high resolution, enabling more reliable and efficient surge voltage analysis.

Example: Observation of motor surge of SiC MOSFET_1

Example: Observation of motor surge of SiC MOSFET_2

Example: Observation of motor surge of SiC MOSFET
