    • The invention relates to a method for load detection on a solid state actuator/motor device (0), comprising a shaft (2), a drive body (4) with an opening (40), through which the shaft (2) runs and at least two solid state actuators (3) on the drive body (4), wherein the solid state actuators (3) may be controlled by a control parameter (u(t)) for activating the drive body (4) to set the shaft (2) in rotation, wherein a load torque (M) is determined by a parameter taken from a solid state actuator, a load dependent parameter (q(t)), arising from the load torque (M), being measured as the parameter at at least one of the solid stater actuators (3), a phase difference (?f) between the control parameter (u(t)) and the load-dependent parameter (q(t)) is determined and the load torque (M) determined by means of the phase difference (?f). The invention further relates to a device or circuit for carrying out said method.
    • 本发明涉及一种用于负载检测的方法在固态致动器的驱动装置(1),一轴(2),驱动体(4)具有开口(40),通过这导致所述轴(2),和至少两个固态致动器 (3)到致动器主体(4),其中,所述固态致动器(3)由一控制量的装置(U(t))的控制,以激励驱动体(4),用于在旋转使所述轴(2),其特征在于,负载转矩(M) 由固态抽头尺寸来确定,导致大于负载扭矩(M)与负荷有关的变量(q(t))的中的一个的大小在所述固态驱动器中的至少一个(3),相位差被测量(τf)的(控制变量之间 u(t))和负载相关变量(q(t)),负载力矩(M)通过相位差(Δf)确定。 此外,本发明涉及用于执行这种方法的设备或电路。
