TEAM problem 30A - Three-phase induction machine

This is an example of a three-phase induction machine. It is designed as part of a TEAM benchmark problem in order to test software codes for their accuracy for analyzing such devices. In MagNet, this device is analyzed using the Transient 2D solver with Motion and the case study that is presented here displays the characteristics of the machine during startup. In this analysis, no load or friction is specified.

Results

The torque/time graph shows the initial transient that takes place and the way the torque changes as the rotor speeds up. The torque, then, reaches the maximum before dropping to zero at synchronous speed.

The speed/time graph shows the speed of the rotor increasing from zero at start to the maximum attainable speed when the machine is running at synchronous speed.
