Background technique [0002] In production and scientific research, it is not only necessary to carefully design various dynamic parameters of mechanical equipment, but also to dynamically measure various parameters such as torque, real-time power, average power, speed and the energy it consumes. This can obtain important field parameters for the further improved design of mechanical equipment, and obtain comprehensive first-hand information for improved design. It is of great significance to production and scientific research. [0003] At present, ordinary torque detection devices usually use brake pads or magnetic powder brakes. Due to their own material and structural characteristics, neither of them can perform effective braking when performing torque detection of high-torque electric actuators, resulting in large...
