Driver DPFLex ™

Brushless DC motors and drives are replacing traditional electric motor technologies such as single phase AC induction motors and universal motors in increasing numbers, driving fans, pumps and compressors used in industrial and commercial applications.

DPFlex™ eliminates the need for Hall sensor feedback necessary for motor commutation in conventional brushless DC motor drives. DPFlex™ detects motor rotor position at motor standstill through an innovative algorithm based on motor phase-inductance measurement, in order to start the motor reliably, unidirectional and without any startup delay.DPFlex™ provides sensorless control of BLDC motors at performance levels that exceeds the performance of conventional Hall commutated drives. DPFlex™ can be integrated into the motor bell-end or operate as a separately mounted device.
