Abstract: A motor for driving a load, such as a tool or a workpiece, can be installed in a machine, for example an eccentric lathe. The motor has an output-drive section associated with the useful load, a reaction section which interacts with the drive section, and a base that rigidly supports the motor in the machine. The reaction section of conventional motors is typically rigidly attached to the machine, so that vibration can be introduced in the machine bed if a strong force is transmitted to or received from the load. According to the invention, these vibrations can be reduced or eliminated by mounting the reaction section on the base in such a way that any movement by the output-drive section can be compensated by a corresponding opposing movement of the reaction section. The inertia of the reaction section hence compensates the corresponding opposing forces in the event of sudden or strong acceleration of the load.
