(420) The V series utilizes a comprehensive set of noise-reduction technologies: a special tooth-surface machining technology to remove cutting marks from the surface of the motor shaft teeth, an optimized quiet-running design that considers circular speed of the motor while maintaining its strength, and a high-accuracy assembly technology that ensures precision at micron levels.
(1,102) Capacitor-run, single-phase motors. The outward appearance is the same as that of induction motors, however, these motors are suited for applications where the motor must frequently switch direction.
