An adaptive active balancing algorithm is developed to realize rotor unstop balance. Based on a single-plane influence coefficient balancing equation
the mathematical model of a single-plane online adaptive balancing is establishedby introducing a gain factor to improve the stability of balancing iteration process and introducing a forgetting factor to realize the online estimation of influence coefficient. To verify effectiveness of this proposed balancing method
an electromagnetic ring active balancer with permanent magnet is designed
where the interaction of magnetic field between coil and permanent magnet drives the counterweight disk step by step
its
self-locking is realized following minimum magnetic resistance principle. For the designed electromagnetic balancer
a single-disk rotation balancing strategy is proposed
and the phase of balancing compensation is calibrated. The active balancing test of a motorized spindle under different unbalance and speed is carried out
and the time-domain waveform
amplitude reduction rate
balancing step number and the final position of counterweight disk are obtained. Test results show reduction of amplitude by 42.65% for the imbalance of 24.59 g·cm∠180°
and by 37.8% for 24.59 g·cm∠285°; also
test results show reduction of amplitude by 40% at 2 400 r·min
-1
and by 60% at 3 000 r·min
