ABSTRACT:
A control unit for an electric drive motor of industrial processing machinery includes a control arrangement which drives a pair of magnets generating a magnetic flux and a Hall effect sensor disposed between the magnets so as to be swept by the magnetic flux rotatively with respect to each other; the Hall effect sensor outputs an electric signal which varies consistently with the position setting of the control arrangement and drives the electric motor accordingly; the movement of the control arrangement is resisted by springs having different degrees of stiffness from one another; proper interaction can thus be established between the operator and the machine.
