ABSTRACT:
A training device is proposed having a crank for a training device for the physically disabled includes a crank, an electric motor which is connected to the crank, power electronics which are designed at least for driving the motor, and means for regulating and/or controlling the rotation speed at the crank. The training device for the physically disabled, makes it possible to use their residual movement capabilities and residual muscle power, in order to ensure a training sequence that is as effective as possible. The means for regulating and/or controlling the rotation speed are designed for a rotation speed change .DELTA.n as a function of the torque M.sub.K on the crank .DELTA.n=f(M.sub.K), a new rotation speed n.sub.new being obtained from the old rotation speed n.sub.old in accordance with the relationship n.sub.new =n.sub.old +.DELTA.n, and the function .DELTA.n=f(M.sub.K) being different for specific value ranges of M.sub.K defined in advance. In a further embodiment, the means for regulating and/or controlling the rotation speed are designed for a rotation speed change .DELTA.n in such a manner that, if an energy input E.sub.K has already been supplied by the trainee applying a torque M.sub.K to the crank and this has led to a rotation speed increase, a rotation speed increase .DELTA.n remains if, immediately after the energy input, an amount of energy is taken from the mechanical system which is present in the training device or is modeled electronically, which amount of energy corresponds to a value which results from the energy input E.sub.K minus the energy loss resulting from the braking torque M.sub.B and/or friction torques M.sub.R.
