ABSTRACT:
In a grinder, the table carrying the workpiece to be ground reciprocates to carry it past a grinding wheel. The table moves armatures oppositely into and out of respective coils, inducting voltage therein for driving the reversible motor that moves the table. Remote coils with manually settable armatures therein oppose the first coils for determining the range of movement of the table. A control circuit includes right and left halves corresponding to the directions of movement of the table. Right and left SCR's control the current from first coils to the drive motor, transistors control the gating current to the SCR's; triacs control the current from the transistors, and other triacs control the current from the main source to the drive motor.
