Dynamic testing of electrical machines for industrial use A unique test facility for dynamic testing of electrical machines for industrial use is part of SP’s Battery and Hybrid Systems section. In comparison with the conventional static way of testing electrical machines, with a test bench and torque sensors, dynamic testing offers a more cost-effective, less time-consuming and more flexible way of evaluating the characteristics of electrical machines. The dynamic test method for motor-mapping of Permanent Magnet Synchronous Machines (PMSM) is based on the use of the rotary momentum of the electrical machine. No external load is necessary, as required by the static method. The mobility of the method means that machines can be tested under a wider range of conditions and in different environments. By using a unique resolver calibration for each individual electrical machine, accurate measurements for the deceleration/acceleration can be obtained. The whole process is monitored and controlled by a real-time controller with a dedicated Field Programmable Gate Array (FPGA) programmed in LabVIEW. SP offers: • Verification of PMSM designs • Optimisation of motor control systems • Performance measurements • Prototype and development tests • Performance tests for different environmental conditions Contact persons Daniel Olsson [email protected] +46 10 516 58 43 Lars Hoffmann [email protected] +46 10 516 58 63 SP Technical Research Institute of Sweden Electronics Box 857, SE-50115 Borås, Sweden Phone: +46 10 516 50 00 E-mail: [email protected], www.sp.se
