    Abstract: This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a first permanent magnet provided in one surface of the impeller, and a second permanent magnet provided in an inner wall of the blood chamber, for attracting the first permanent magnet. The attractive force between the first permanent magnet and the second permanent magnet on the opening side of a sidewall of the blood chamber is set to be smaller than the attractive force between the first permanent magnet and the second permanent magnet on the opposite side of the opening. As a result, inclination of the impeller with respect to a dividing wall during pump operation can be prevented.

    Abstract: A vehicle drive motor, capable of efficiently cooling the motor stator without being accompanied by an increase in size, includes a stator having an annular stator core, provided in an inner periphery of a tubular motor casing, and a stator coil provided in the stator core, and a rotor on an inner side of the stator core and rotatable relative to the stator. The motor casing includes an oil supply passage and an oil discharge passage in the motor casing and opening at an inner diametric surface of the motor casing, which are opposite axially to each other. Stator core grooves communicated with the oil supply passage and the oil discharge passage extend axially in an outer diametric surface of the stator core. Accordingly, lubricant oil may flow from the oil supply passage towards the oil discharge passage through the stator core groove.

    Abstract: An electric vehicle includes a slip ratio estimator that estimates a slip ratio based on rotational frequencies of respective driven and drive wheels. The vehicle also includes a disturbance observer that determines an estimate of a torque attributable to external force. The vehicle also includes an estimator that may estimate an entire torque to the drive wheel, based on a motor torque command value and the estimate of torque. The vehicle also includes an estimator that estimates a coefficient of friction between a road surface and a tire, based on the entire torque and the slip ratio. The vehicle also includes a determiner that determines a maximum acceptable torque Tmax, based on the coefficient of friction and a vertical load component. Torque limitation is performed such that the motor torque command value does not exceed the maximum acceptable torque Tmax.
