In our very last Productivity Forum, we concentrate on one of Nikola Tesla's most significant inventions — the ac motor. In this report, Motion System Design editors polled ac motor experts for advice ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

As is ever the case with engineering design, the primary trade-offs occur between power (energy), performance (efficiency), and area (miniaturization). While this is especially true in designing ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.
