Technical Examples
  1. A conveyor unit (2) including a driving roller (5), a motor (30) for powering the driving roller (5), and a controller (10) adapted to adjust the motor (30) so as to control the driving roller (5), the motor (30) including a permanent magnet and an armature having a plurality of armature coils (32a-32c), and the controller (10) having an interrupter (15) adapted to repeat shunting and deshunting of at least one of the coils (32a-32c) and a rotation detector (17) adapted to detect an externally forced rotation of the motor (30) in response to an electromotive force induced in at least one of the coils (32a-32c), wherein in the case that the motor (30) is not driven, the controller (10) maintains operations of the interrupter (15) and outputs a presence signal by determining conveyance of an article (W) into an area powered by the motor (30) upon detection of the rotation of the motor (30) by means of the rotation detector (17).
