Claim Text:
1. An apparatus for controlling asymmetrical coasting of an endodontic reciprocating motor, the apparatus comprising: an endodontic motor that is capable of rotating a tool in a clockwise direction and in a counterclockwise direction, and a controller that is operatively coupled to the endodontic motor and is capable of: (i) transmitting electronic signals to the endodontic motor to change the direction of rotation of the tool from the clockwise direction to the counterclockwise direction, (ii) controlling angular momentum of the endodontic motor in the clockwise direction to determine an amount of dynamic angular rotation during a forward coast, and (iii) controlling angular momentum of the endodontic motor in the counterclockwise direction to determine an amount of dynamic angular rotation during a reverse coast, wherein the amount of dynamic angular rotation in the clockwise direction is different from the amount of dynamic angular rotation in the counterclockwise direction.
