When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

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 ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

In low-cost, high-speed motor applications, especially those inside the home, the universal motor dominates. They are as ubiquitous as the countertop blenders and the power tools they inhabit. But not ...

As servo drive technology evolves, manufacturers face inevitable product lifecycle changes that require proactive evaluation of aging motion control systems before replacement parts become scarce and ...
