Measuring power and efficiency in five‑phase electric machines introduces new challenges compared to conventional three‑phase systems. This whitepaper shows how HBK GEN4tB transient recorders and Perception software enable accurate electrical and mechanical power measurements for an inverter‑fed five‑phase PMSM.
Based on a real test bench at TU Darmstadt, the paper presents a practical measurement workflow using a four‑wattmeter method and MATLAB post‑processing to overcome increased phase count and hardware limitations. It also analyzes torque and efficiency behavior under fundamental and third‑harmonic current injection, demonstrating the flexibility and precision of HBK solutions for advanced electric drive testing.
