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 7):
The power tool of  claim 1  wherein the controller is configured to determine tool startup and control power output of the BLDC motor by setting conduction band of the plurality of motor switches and advance angle to the baseline values during tool startup.
