6/30/00<br>Also, the torque behavior will influence the rotor bar life cycle. Any abrupt torque changes shall be mitigated by a flywheel, electromagnetic shaft coupling, etc.

6/30/00<br>One may use passive harmonic filters, active harmonic filters, motor drives with phase shifting transformers (rectifier or pulse transformers), and some combination of phase shifting transformers with passive harmonic filters. However, the cost analysis comparison study is recommended...

6/30/00<br>There appears to be initial average winding temperature limitations involved, e.g. less than 75 deg C. It is probably better to check with the transformer manufacturer before the application/purchase of the zig-zag grounding transformer is completed, just in case.
