[Robert Murray-Smith] doesn’t like the price of inverters to convert DC to AC. That led him to build a dynamotor, or what is sometimes called a motor-generator set. These devices are just DC motors ...

During the constant worldwide campaign to make the planet as clean as possible, electric vehicle (EV) drivers have an improving chance of driving cars with fewer moving parts. One of an EV’s greatest ...

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 ...

Today, most electric machines operate with radial flux (RF). Magnax offers a new concept, though—a machine that operates with axial flux (AF). Figure 1 provides a comparison of the RF and AF ...

A new edition of the only American national standard for repair of motors and generators — “ANSI/EASA AR100-2010: Recommended Practice for the Repair of Rotating Electrical Apparatus” (ANSI/EASA AR100 ...

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.
