Abstract: A magnetic geared electrical machine includes: a stator; a magnetic pole piece rotor including a plurality of magnetic pole pieces disposed radially inward of the stator; an inner rotor including a plurality of rotor magnets, disposed radially inward of the plurality of magnetic pole pieces, and configured to rotate at a higher speed than the magnetic pole piece rotor; and a fan for cooling at least one of the stator, the magnetic pole piece rotor, or the inner rotor. The magnetic pole piece rotor further includes a power transmission shaft disposed on one side in an axial direction relative to the plurality of magnetic pole pieces, and configured to transmit rotational power to and from an external device. The fan is disposed in the inner rotor on an opposite side to the power transmission shaft with the rotor magnet therebetween in the axial direction.

Abstract: A microprocessor operation monitoring system whose own tasks are constituted by associating beforehand the task number of the task that is next to be started up, for each of the tasks constituting the program, and abnormality of microprocessor operation is detected by comparing and determining whether or not the announced task and the task to be started up match.
