This application note presents space vector control or field-oriented control (FOC) using polar coordinates. It is used for controlling 3-phase alternating current induction motors (ACIM). The ...

The past few decades have seen a rise in the use of field-oriented control in induction motor applications. One advantage of field-oriented control - The past few decades have seen a rise in the use ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

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 ...

Digital signal controllers enable drives for permanent magnet synchronous motors to be optimized with complex algorithms at low cost. When used in an appliance, a permanent magnet synchronous motor ...

Three-phase brushless motors offer many benefits including economy, reliability and high efficiency, but also exhibit poor dynamic performance. By implementing proper control algorithms (such as field ...

An average electric vehicle (EV) user has no idea about Field-Oriented Control (FOC) algorithm that works silently under the hood. But people in the know of things will swear by its ability to drive ...
