Tirius has developed its own test facilities for characterisation and validation of high speed machines. As well as testing Tirius products these facilities are available for testing client machines and power electronics. A further option is to provide equipment for on-site testing at client locations. The test facility features wide-bandwidth electrical power measurement for inverter and motor input. High bandwidth torque measurement is synchronised to the electrical measurements with continuous logging of the key operational parameters of the unit under test. In addition, the test facility provides controlled temperature liquid cooling and multi-channel logging of both system and component operating temperatures, flow rates and pressure.
