Advantage of Intelligent Phase Control

Intelligent Phase Control detects the motor current phase and feeds back the information for auto lead angle control. When a motor application has a sensor, the phase of the Hall signal is automatically adjusted to match that of the motor drive current.
High efficiency is achieved regardless of the rpm, load torque and power supply voltage of a motor. Intelligent Phase Control also helps reduce the number of external parts necessary for lead angle adjustment.
