How to design an induction machine

The Induction Machine (IM) is the most widely used type of electrical machine. By some estimates it accounts for 90% of all small size motors (10 – 750W) and 60 -70% of medium size motors (0.75 – 375 kW). This is mainly due to their reliability, low cost and wide range of torque / speed [...] Posted in How to...,Induction Machines,Motors
