The principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For as long as this type of control considers the ...

The National Electrical Manufacturers Association has published ICS 7.2-2015 Application Guide for AC Adjustable Speed Drive Systems. This guide assists users in proper selection and application of ...

Direct torque control is a motor-control method for ac drives that accurately regulates motor speed and torque without encoder feedback from the motor shaft. Eliminating encoders can simplify ...

Applications often end up with poorly-specified drives and other motion-control components. Often that is because engineers and designers overlook characteristics such as motor type, torque, power and ...
