Abstract (en)

[origin: EP2515185A1] The motor has a power accumulator i.e. strip (14), for accumulating and restituting power to drive a mechanical mechanism between armed state and unarmed state. A controller i.e. rotary part integrated control device (E), controls the accumulator by relative displacement between the controller and the accumulator such that torque created by the accumulator remains constant between the armed state and the unarmed state. The strip has side surface that is toothed and gripped with corresponding teeth on wheels (12, 18) of the controller. The strip is formed from silicon, silicon coated with silicon dioxide, silicon coated with diamond or diamond.
