Abstract

The device comprises a stepper motor and an electronic circuit suitable for delivering, with each step of the motor, a motive pulse, then for short-circuiting the coil of the motor so as to brake the rotor. With a view to reducing energy consumption, the electronic circuit is designed so that the short-circuiting of the coil begins only after an intermediate period during which no current flows in the coil.
