Abstract
A concrete vibrator system includes a concrete vibrator having a motor, a vibratory head that is actuated by the motor, and a controller that controls the motor. The concrete vibrator system may also include one or more remote devices or servers that wirelessly communicate with the controller of the concrete vibrator. The remote device may monitor the speed output by the motor and the voltage supplied to the motor to achieve a set speed via the controller, and display information representative of the motor speed and motor voltage to the user. Moreover, the speed output by the motor may be controlled using voltage supplied to the motor.
