Investigation of different servo motor designs for servo cycle operations and loss minimizing control performance

Servo motors are widely used in many industrial applications. These motors require precise control of acceleration, speed, and position. Different designs can be found in the literature. This paper will compare the response of two of the common types and will propose a new servo motor design that uses a smaller amount of magnet, lowering the price of the motor. The proposed motor would be able to save energy for the required application (minimize the cost of the industrial process) and would be suitable for high-frequency injection based self-sensing techniques.
