If you made a motor out of a magnet, a wire coil, and some needles, you probably remember that motors and generators depend on a rotating magnetic field. Once you know how it works, the concept is ...

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 ...

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 ...

Variable-speed drives for three-phase motors are ubiquitous components of industrial systems that help save energy and optimize performance. Traditional, scalar control techniques for variable-speed ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control over a connected motor, through the precise control of its phases. In a ...

Sizing conductors and protection for rotating electrical equipment is commonly required in the field and on exams. The rules ...

The leading and longest established online Process Engineering publication serving the Process Manufacturing Industries ...

How the switched reluctance motor's (SRM) architecture eliminates the need for magnets and rotor windings. Why SRMs are some of the most rugged and cost-effective motor technologies available. A look ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
