Apparatus and method for asymmetrical coast control of an endodontic motor

摘要

An apparatus for controlling asymmetrical coasting of an endodontic reciprocating motor includes a controller operatively connected to the endodontic motor. The controller may include a processing unit that is configured to direct the rotation of the endodontic motor in the forward direction for a coast time and configured to direct the rotation of the endodontic motor in the reverse direction for a coast time. The forward coast time is separately calculated from the reverse coast time. A method for asymmetrically coasting a reciprocating endodontic motor includes rotating an endodontic motor in a forward direction and calculating a forward coast time for the forward direction and coasting the endodontic motor in the forward direction for the calculated forward coast time. After coasting the endodontic motor in the forward direction, the endodontic motor is rotated in a reverse direction. The reverse coast time is different than the forward coast time.

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.
