  • Concrete vibrator system and motor therefor
    Publication number: 20120092948
    Abstract: A concrete vibrator system with a constant speed motor, one of a set of vibrator heads with different load characteristics, and one of a set of drive shafts connecting the motor output shaft with one of the vibrator heads. A speed control circuit senses motor shaft speed and maintains constant speed. The motor is cooled by a fan mounted on the motor rotor which draws air through an inlet and exhausts air through an outlet both of which face downwardly when the motor is in use. Rain or other liquids are prevented from reaching the motor.
