The contactor is mechanically and electrically configured to prevent simultaneous forward and reverse. The DC motor output is fed from the contactor to the spindle motor with a large 10mH inductor in series, presumably to compensate for the low inductance of the motor. === Spindle === ▲The spindle motor controller has been replaced with an RS speed controller. The motor is a Lenke 18V DC motor. An optical encoder is mounted on the spindle (50 Pulse/rev). === Limit Switches === Product Number: IS-3002-ANOG
