Because AC motors require frequency to spin, the drive must provide the required energy waveform with enough voltage to deliver the needed current to produce magnetic flux within the motor. The motor ...

High Frequency Drive High frequency drives supply power to AC motors at frequencies much higher than standard power frequency for high-speed industrial applications. TRIAC Control A drive that uses a ...

To some, motor speed control is somewhat of a mystical science, a science that causes motors and machines to sometimes operate in unexpected ways. Over 30 years ago, AC drives were considered "new ...
