This invention discloses a planar spiral spring fatigue testing machine, comprising a base, a mounting seat fixedly mounted on the base, a reducer fixedly mounted on the mounting seat, a servo motor fixedly mounted at the rear of the reducer, and mounting brackets symmetrically mounted on the left and right sides of the mounting seat. Each mounting bracket is equipped with a rotatable rotating shaft. The output shafts at both ends of the reducer are nested and fixedly connected to the rotating shafts on the mounting brackets, and the rotating shafts on the mounting brackets are arranged symmetrically front to back. In this invention, the rotating shafts on the mounting brackets are arranged symmetrically front to back and have positioning grooves, so that the spiral springs to be tested are symmetrically installed. After one end is placed, the other end needs to be rotated 180 degrees counterclockwise. The servo motor drives the reducer to rotate, and the reducer and rotating shafts rotate together, causing the spiral springs to rotate. The spiral springs at both ends rotate in the same direction, and the forces on both sides cancel each other out. The torque of the servo motor can be smaller, making it more energy-efficient and effective.

This invention discloses a direct control method for torque and axial force of a linear rotary switched reluctance motor. First, the sector containing the flux linkage vector is determined through calculation. Based on the flux linkage hysteresis signal and the torque hysteresis signal, the voltage vector required for control is determined. Then, the axial force is controlled within the control range of (-15°, 15°) where the rotor position is selected. The corresponding axial force voltage vector is selected based on the axial force hysteresis signal. Finally, the operating mode of each power converter switch is determined based on the signs of all voltage vectors. This invention significantly reduces torque and axial force pulsation by directly controlling the motor's torque and axial force, resulting in a faster system response. Operating modes for the torque winding and axial force winding are established separately for torque and axial force, respectively, leading to more reasonable vector selection. Furthermore, no model calculation is performed during the control process, so the control accuracy does not depend on the analytical model, improving the system response speed and simplifying the control strategy.
