Abstract
A method is disclosed for improving the performance attainable in a motor-driven system of the type characterized by a single motor driving an output shaft operatively coupled to a motor-driven device, the single motor characterized by a first power and a first peak rate of acceleration, the method comprising: Providing at least two motors in place of the single motor, each of the at least two motors being characterized by a second peak rate of acceleration significantly greater than the first peak rate of acceleration, and the at least two motors further characterized by a combined power that is at least equivalent to the first power of the single motor; and operatively coupling the at least two motors in parallel to a common output shaft driving the motor-driven device such that the second peak rate of acceleration is efficiently translated to the common output shaft.
