Abstract:
Conduction band control schemes are presented for reducing noise and/or lower harmonics in power tools. A controller in the tool is interfaced with a plurality of motor switches and, for each phase, operates to output a pulse-width modulated (PWM) signal to one or more of the motor switches to control power supplied to the electric motor. The controller is also configured to monitor a parameter indicative of the load on the motor. In response to detecting a load greater than a threshold, the controller controls power output of the motor by setting conduction band of the motor switches and the advance angle to baseline values predetermined values. In response to detecting a load less than the threshold, the controller reduces at least one of the conduction band and the advance angle to a value less than the baseline values.

Claim (Index 18):
The power tool of  claim 17  wherein the BLDC motor is configured to operate in three phases and the controller, in response to detecting a load greater than the threshold, sets the conduction band to 120 degrees for each phase and the advance angle to 30 degrees for each phase.
