The Microprocessor Torque Meter for Car Test Stands with an Induction Motor as a Load

Always for means of test and diagnostics of car units are made great requirements. First of all there are technical, economic and ergonomic requirements, and also requirements of increased reliability, ecology and high operational qualities. The necessity of a measurement of the torque exists in many car test stands. In a number of stands as the load for an engine the electrical machines are used. Balance machines have the broadest application. Also the torque of the electrical machines is often measured approximately regarding the input current. Sometimes more complex estimations are applied.
