Aiming at problems of real-time measurement of dynamic and static torques of motor

use switched reluctance motor as research object

a measurement solution method for real-time measuring motor dynamic and static torques is proposed

and motor torque measurement system is designed. The principles of the program is that the deformation of elastic coupling is detected by two resolves when it is subjected to torque effect

and FPGA +ARM control architecture is designed

it can detect dynamic and static torques of the motor torque in real time and accurately. Static torque is test according to JJG 2047—2006 Verification Scheme of Measuring Instruments for Torque method

the maximum relative error of static torque is 0. 73 %. Dynamic torque is validated by precise dynamic torque device

the maximum relative error of dynamic torque is 0. 68 %.
