Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...

With the goal of reducing reluctance torque, the Series 14000 brush-commutated, dc and gear motors employ 11-slot skewed armatures that promise to minimize magnetic cogging. The dc motors are ...

All the motors produce either interaction torque, reluctance torque or a combination of both. The second article in this series discussed the underlying principles common to all motors. As we have ...
