Abstract: The torque ripple of an electrical machine will affect the control accuracy and trigger vibration and noise in the system. Consider only the motor itself, the torque ripple is mainly caused ...

Abstract: In this paper, we address the problem of dynamically dispatching a group of deloaded wind generators (WGs) in an equal sharing manner while their total power is tracking a given reference.

Selecting a motor for a specific application can be a challenging task. Many factors must be considered, including the application’s required voltage, maximum current and diameter, speed, efficiency, ...

The optimal size for a clutch or brake is determined by three things: Required torque, thermal horsepower per engagement, and average required thermal horsepower. Here, we'll discuss the first, ...

Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.

Sometimes the hardest part is getting started. Choose the best motor starting method for a particular application by keeping a few guidelines in mind. For example, while across-the-line starting is ...

Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.
