In the development of a magnetic-coupling water pump, the pulling-out (disengagement) of a coupling that led to the stopping of an impeller was a concern. Upon analysis of the behavior of the magnetic coupling, presence of two types of the pulling-out was found, that is, the pulling-out resulting from a lack of transfer torque in the high-speed revolutions and the pulling-out due to the resonance of an inner magnet and an outer magnet. Main factors that affect the pulling-out are the angular velocity input to the drive side, the moment of inertia of the driven side, characteristics of the magnetic coupling, and a damping from coolant. Using a measurement and simulation of the behavior of the water pump, factors were analyzed and the process of pulling-out was clarified. As a result, design specifications that prevented the pulling-out were established.
