Power tool having rotary input control
First Claim
1. A power tool comprising:
- a housing;
a motor contained in the housing;
an output member at least partially received in the housing and configured to be driven by the motor to rotate about a longitudinal axis;
a reaming attachment having a front end portion configured to be selectively driven in rotation by the output member to drive a fastener into a workpiece, and a reaming portion configured to be selectively driven in rotation by the output member to remove material from an end surface of a conduit;
a rotational motion sensor disposed in the housing and operable to detect rotational motion of the housing about the longitudinal axis; and
a controller disposed in the housing to receive a signal indicative of rotational motion from the rotational motion sensor, to determine a direction of the rotational motion of the housing about the axis and to drive the motor in a direction corresponding to the direction of rotational motion of the housing.

Abstract
A power tool includes a housing, a motor, an output member driven by the motor, and a reaming attachment coupled to the output member. The reaming attachment has a front end portion selectively driven in rotation by the output member to drive a fastener into a workpiece, and a reaming portion selectively driven in rotation by the output member to remove material from an end surface of a conduit. A rotational motion sensor in the housing is operable to detect rotational motion of the housing about an axis. A controller receives a signal indicative of rotational motion from the sensor, determines a direction of the rotational motion of the housing, and drives the motor in a direction corresponding to the direction of rotational motion of the housing.
