CONCRETE VIBRATOR
A concrete vibrator includes a housing having a motor housing portion extending along a longitudinal axis and a handle portion extending transverse to the longitudinal axis and spaced from the motor housing portion, defining an opening between the handle portion and the motor housing portion. The concrete vibrator also includes a trigger, a brushless DC electric motor positioned within the motor housing portion, a battery pack configured to provide electrical power to the electric motor to drive the motor, and an electronic processor electrically connected with the motor and the battery pack. The electronic processor is configured to adjust the electrical power to the motor in a closed loop to maintain operation of the motor at a rotational speed set point. The concrete vibrator also includes a vibrator head configured to receive torque from the motor, causing the vibrator head to vibrate.
