Direct electromechanical drives are the simplest possible transmission systems requiring no additional mechanical components such as gearboxes or rotary to linear converters. This simplicity leads a number of advantages including greater reliability, less maintenance, improved dynamic characteristics and reduced weight and volume. However, the performance specification of direct drives is usually high, with a correspondingly high cost, and often this cannot be justified in complete systems where the other components limit the overall performance. This factor alone has been sufficient to restrict the market penetration of direct drives. The majority of applications are in linear actuators, and in motors operating at very high or very low speeds. new developments are constantly being introduced, especially in relation to structures.
