Abstract
A Brushless Direct Current (BLDC) motor controller comprises a first terminal for applying a first voltage and a second terminal for applying a second voltage to obtain a driving current for driving a BLDC motor. The BLDC motor controller comprises a remote control unit which is adapted for monitoring a signal which is indicative for a current through at least the first or the second terminal. The BLDC motor controller is adapted for increasing the monitored current by applying an additional current. The additional current is different from zero if the motor is rotating. The BLDC motor controller is adapted for determining whether the motor is rotating or not, based on the monitored signal.
