A starter for an internal combustion engine is comprised of an armature, a motor case, a planetary gear speed reduction mechanism connected to an armature shaft, a frame and a partition plate disposed between the motor case and the frame. A persistent connection may be a connection that persists for longer than the usual SAS connection. The first PLL circuit part is provided with first and second variable frequency dividers which respectively divide the reference frequency signal and the output of the first voltage controlled oscillator. Pistons are mounted within each of the bores for axial movement relative to the cylinder block. A corresponding micromechanical component is also described.
