The disclosed invention is an innovative, cost-efficient driving mechanism for the prosthetic hand industry that makes the use of only one motor to individually control each digit on a prosthetic hand separately. The use of the novel electromagnetic actuation system, locking mechanism, and spline nut and shaft configuration coupled with the single motor greatly reduces the weight, size and power usage of the prosthetic, increases functionality, minimizes noise, increases and speeds and forces, and orients the parts of the device in a manner that creates an aesthetically appealing design.
