Power analysis on electric motors: a challenge for measurement technology


Electric drives have become an integral part of our everyday lives. To increase efficiency and reliability, they need to be extensively tested.


Whether in cordless screwdrivers, on e-bikes or in electric cars - electric drives must function with maximum efficiency over the largest possible load ranges.

Power analyzers are therefore used on electric motors to check electrical performance parameters. These measurements are used to monitor the efficiency, energy consumption and operating behavior of the motor.

Compliance with test standards can pose a real challenge for the measurement technology used. For example, a maximum error deviation of 0.3 % is permissible when measuring power. What's more, today's electric motors have to become ever more powerful. Battery voltages of up to 800 V are currently being used in electromobility in particular.

Such requirements are no problem for our LTTsmart precision measuring device as a power analyzer. Our measurement technology is unique in the world, because no other power measurement device can meet the signal-side accuracies required by the standards for voltage and frequency. Due to the low noise level of the Power Analyzer, even the smallest deviations can be recorded with the data acquisition device.
