Design of PMSM-based electric motor test stand

A part of the CAAEEC project is focused to create a modern test stand working on the principle of an electric brake and intended for testing of electric drive systems up to ca. 1 kW. The main difference and advantage of this test device compared to traditional dynamometers is its electronic controllability with a low latency - the requested instantaneous brake torque can be dynamically set based on measured quantities of the system under test; Field-Oriented control is employed. In this paper, a proof-of-concept implementation of the test system is described which is not expected to achieve full load power.
