The invention relates to a pump motor halt coasting time control loop. An electric appliance control loop is mainly composed of three parts: a pump motor (M), a main circuit (ABC) and a control circuit (ab); the control loop is characterized in that the rotational speed of the pump motor (M) is gradually lowered in the halt process through the time control effect of the control circuit (ab), the adjusting of the connection of the main circuit (ABC) and the adding of a resistor in the halt running process of the pump motor (M), thereby achieving aims of prolonging the halt time, reducing the water flow impact caused by the inertia of the water, improving the running stability of the pump loop, and prolonging the service life of the pump and related components.
