Abstract
A first and/or a second electrical machine is tested using a test apparatus that includes a torque transmitter having torque connections for the first and the second electrical machine and an electrical shaft having respective electrical connections for the first and the second electrical machine. The electrical shaft is designed to transmit at least five times as much electrical power between the respective electrical connections as can be supplied by a supply apparatus of the test apparatus from an external electrical energy source to the electrical shaft. This condition is assumed to be satisfied when the test apparatus lacks such a supply apparatus. A corresponding method using such test apparatus is also disclosed.
