ML4411 controller equivalent, sensorless spindle motor controller.
s s s s s s s Back-EMF commutation provides maximum torque for minimum “spin-up” time for spindle motors Accurate, jitter-free phase locked motor speed feedback output Li.
The ML4411 provides complete commutation for delta or wye wound Brushless DC (BLDC) motors without the need for signals from Hall Effect Sensors. This IC senses the back EMF of the three motor windings (no neutral required) to determine the proper co.
