Abstract
Embodiments of the disclosure provide a system and method of operating a motor control algorithm in a power tool to utilize dynamic field weakening. The method includes operating the motor according to dynamic field weakening, measuring sensor readings, and sampling the sensor readings. The method also includes calculating an averaged sensor reading value, comparing the averaged sensor reading value to a predetermined sensor value, and continuing to operate according to dynamic field weakening if the averaged sensor reading has not exceeded the predetermined sensor value. The method further includes changing the motor control algorithm to a static motor commutation sequence if the averaged sensor reading has exceeded the predetermined sensor value.
