Conveying device for persons, with directly driven step bodies and a step body for such a device

A step body for a conveying device, the step body including running rollers, at least one of the rollers being driven by electric motor mean mounted on the step body, the motor means comprising two mutually independent electric motors, each of the motors being coupled to a separate running roller;

• current supply means for at least the motor means;
• at least one sensor for determining the spacing of the step body from an adjacent step body;
• and a control electronic system coupled to the motor means and the at least one sensor to control the motor means in accordance with a signal from the at least one sensor.
