This paper presents an improved synthetic
loading method to measure the performance of an interior
permanent magnet synchronous machine (IPMSM). A
complete analysis of torque-, flux-, and efficiency-maps are
done by means of a vector controlled drive implemented with in
a field programmable gate array (FPGA). The measurements
are compared to results from Finite Element Analysis (FEA). A
key feature of this implementation is an instantaneous
measurement of the inverter output voltage that facilitates
estimation of the input power of the machine. The synthetic
loading technique completely eliminates the need for a torque
transducer, load machine and holds a control over temperature
development during the tests. Simulation and experimental
results demonstrate that the supply tracking together with
synthetic loading technique is very useful tool to evaluate the
efficiency of IPMSM.
