Torque measurement methods for very high-speed motors

Purpose - The purpose of this paper is to develop a contactless torque measurement methods. The need for low-weight, high-efficiency and high-power density motors has led to an increased research and development activity in the field of very high speed (VHS) motors or generators. Torque measurement methods are inherently linked with the target speed and power of the motor. Therefore, new torque measurement methods compatible with VHS need to be designed in order to apprehend this new area of electrical machines. In this paper, the target speed is 200,000 rpm.
