Concrete Vibration Handbook

Due to the nature of the universal motor, flex-shaft vibrator motors will continually lose power as the load increases. The stronger the load (such as low-slump concrete), the greater the power loss. The principle advantage is that the 180-cycle induction motor used in high-cycle vibrators will lose only about 5% of its VPM under load.
