Working Principle of DC Motor. A DC motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of the DC motor is that whenever a current carrying conductor places in the magnetic field, it experiences a mechanical force. Fleming's left-hand rule and its magnitude decide the direction of ...

mill work that requires great accuracy. An edge finder helps in finding the edges. •800-1200 spindle RPM is recommended. •To use an edge finder, slightly offset the two halves so they wobble as they spin. •Slowly move the workpiece towards the edge finder. •The edge finder will center itself, then suddenly lose concentricity.

Multi Mill. Product: Multimill. It operates on the principle of variable force swing beaters having both knife and impact edges rotating within a selected screen to get the required size reduction. Material fed in the hopper, goes down to the processing chamber where it moves to the periphery and passes through the screen radially and tangentially.
