A manufacturing method of a stator is a method for manufacturing the stator using molds. The stator is constructed so that a stator main body and resin molded portion are integrated. The stator main body includes a terminal portion and a core. The manufacturing method includes: arranging the stator main body such that the terminal portion is located on a top portion of the molds; and filling a cavity with resin. The terminal portion has a gas discharging port configured to discharge gas out of the cavity from inside the cavity in the molds.

Manufacturing method of stator and stator and motor

In an exhaust purifying apparatus for an internal combustion engine on a vehicle, heating control is executed for supplying fuel to exhaust purification catalysts, thereby increasing the catalyst bed temperature. The heating control is suspended when the vehicle is determined to be driving downhill. Adverse influences due to deactivation of the exhaust purification catalysts during the heating control are reliably avoided.

A regeneration controller for preventing particulate matter from increasing when an exhaust purification apparatus is inactivated. The regeneration controller includes an ECUfor heating the exhaust purification apparatus and eliminating the particulate matter accumulated in the exhaust purification apparatus when an estimated accumulation amount is greater than a reference accumulation amount. The ECUobtains the estimated accumulation amount by estimating the amount of particulate matter accumulated in the exhaust purification apparatus. An exhaust temperature sensordetects the temperature of the exhaust purification apparatus. The ECUintermittently decreases the air-fuel ratio of exhaust to heat the exhaust purification apparatus and perform burn-up heating for burning the particulate matter. The ECUfurther prohibits burn-up heating when the temperature detected by an exhaust temperature sensordecreases to a catalyst inactivation level.
