Anti-kickback control for battery pack powered trowels

Abstract

Systems and methods for controlling a power trowel. A power trowel includes a handle, a housing, a blade assembly, a motor coupled to the blade assembly, a motion sensor, and a controller. The motion sensor is configured to provide an output signal indicative of motion of the power trowel. The output signal includes an orientation signal indicative of an orientation of the power trowel. The controller is connected to the motor and the motion sensor. The controller is configured to receive the output signal from the motion sensor, determine, based on the orientation signal, whether the orientation of the power trowel is greater than or equal to an orientation threshold, and deactivate the motor in response to the angle of the power trowel being greater than or equal to the orientation threshold.
