Abstract:
The invention relates to an electromagnetic actuator to be mounted in a haptic-feedback control device (1) for transmitting a haptic feedback to a user, wherein said actuator (5a, 5b) comprises a fixed portion (9) and a mobile portion (11), said fixed (9) and mobile (11) portions forming a magnetic circuit defining at least one air gap (e) between said fixed (9) and mobile (11) portions. According to the invention, the actuator (5a, 5b) further comprises: at least two permanent magnets (23a, 23b) respectively generating first (B1) and second (B2) opposite magnetic fields; and an electric coil (25) provided between said magnets (23a, 23b) such that the winding of said coil (25) extends successively through said first (B1) and second (B2) opposite magnetic fields so that, when a current flows through said coil (25), the actuator (5a, 5b) is submitted to a resulting actuation force in a common driving direction for translating said mobile part (11) in said air gap (e).
