Force - feedback - joystick - device with single-phase firmly coils actuators

摘要

Force - feedback - interface device, which is a force feedback, to a joystick - handle, the is actuated by a user. A force - feedback - joystick - device outputs control signals to a computer and transmits forces to a user of the joystick - device. The device comprises a housing, which the user of the joystick - device holds it, and a joystick - handle from the user can be actuated in at least two rotational degrees of freedom, for example, a game board. Measuring sensor detecting a position of the joystick - handle, and two actuators with a direct drive in each case represent a torque in a rotational degree of freedom available. Each of the actuators is a brushless, single-phase actuator with a basis of an exciter coil and a movable magnet material. The joystick is mechanically limited thereto, in order to be no inwards. by means of two limits, where the torque outputted by the actuator in a non-activated state changes direction. The joystick - handle can be aligned so that a middle position substantially at a local minimum - resistor position of the actuator is, where the joystick is mechanically limited to extend substantially over no of two local maximum - resistance positions inwards, the to the local minimum - resistor position adjacent. The local minimum - resistor position can in some embodiments, a centering spring force on the joystick - handle providing.
