<p>The training device has a torque generator with an electric motor (2) and a reduction transmission (3) and whose output interacts with at least one exercise element (1) selected by the trainer. The three-phase motor has a frequency inverter (5) as load , which enables the frequency and the amplitude of the three-phase current fed to the motor to be adjusted. The frequency can be adjusted so that the revolution rate of the rotary field deviates from the actual measured revolution rate of the motor by a defined slip revolution rate.</p>
