Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

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 ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...
