Understanding Torque Ripple in Servo Motors

Torque ripple must be defined as a function of output load and speed. For load specification the most sensible rating point is the continuous duty thermal torque rating for the servo motor.

Slotless Brushless Servo Motors Improve Machine Performance.

From the outside it looks just like any other industrial brushless servo motor but inside it utilized advanced manufacturing techniques to provide higher torque, higher speed, smoother operation, higher efficiency, and better inertial matching in a smaller package.

Development of Battery-Free Multi-Rotation Absolute Encoder

In recent years, there have been many demands for equipment with high productivity to have a system that retains positioning information, even after the main power supply is turned off.
