Abstract: According to one embodiment, a redundant address setting circuit can generate a lower peak transient current value during an initial setting operation when defective address information is generated from fuse values. Programming circuits (40-0 to 40-2n) can each include fuses for storing a defective address. The programming circuits are arranged into a first group (40-0 to 40-n) that can be activated in response to a fuse reset signal FRST, and a second group (40-n+1 to 40-2n) that can be activated in response to a delayed fuse reset signal FRST1. The fuse reset signals FRST and FRST1 are activated at different times, distributing transient current generated by the programming circuits (40-0 to 40-2n) over two or more time periods, thereby reducing peak transient current during an initial setting operation.

Abstract: A permanent magnet rotating electric machine that comprises a stator, into which concentratively wound armature windings are inserted in such a way as to surround a plurality of teeth formed in a stator core, and a rotor having permanent magnets accommodated into a plurality of permanent magnet inserting holes formed in a rotor core. In this rotating electric machine, the permanent magnets are convex V-shaped or U-shaped with respect to a rotor axis. Moreover, nearly V-shaped recess portions, each of which is placed between adjacent poles, are formed in outer circumferential surface portions of the rotor core. Thus, torque caused by magnetic flux due to the magnets is increased, while armature reaction magnetic flux generated by an armature current is reduced. Consequently, q-axis inductance is reduced, so that armature current commutation is quickly achieved.
