摘要： The invention discloses a movement detecting device for detecting the movement state of a moving body such as a rotating body, in which a magnetic recording medium on which N and S magnetic poles are alternately recorded at a constant interval is fixed symmetrically with respect to a rotary shaft of a rotating body whose rotation state is to be detected, and an MR element comprising magnet-resistive elements is mounted at a fixed position relative to the magnetic recording medium so that the rotation state of the rotating body can be detected from variation of the values of resistance of the magnet-resistive elements caused by the rotation of the body. N and S poles are recorded on the magnetic recording medium with a small pole pitch P. The magnet-resistive elements are formed to have a width sufficiently smaller than the pole pitch. The magnet-resistive elements constitute a first group and a second group, the magnet-resistive elements of each group being disposed with an interval equal to the pole pitch or half the pole pitch. The magnet-resistive elements are disposed in such a manner that the interval between the groups is deviated from the pole pitch, whereby a circuit comprising these magnet-resistive elements can detect the rotation of the rotating body.

A chopper is provided for controlling the field current of the field winding and a pulse width modulator is provided for controlling the duty cycle of the chopper in response to the operating conditions of the engine. A voltage feedback loop is provided from a normally provided battery which loop incorporates a detector for detecting the actual battery voltage and a comparator for comparing the battery voltage with a predetermined set voltage so that the difference in voltage is rendered to zero. The invention additionally provides a current feedback loop for controlling a deviation between a current command value determining the duty of the chopper and an actual current flowing through the field winding so as to be substantially zero. There is also disclosed means for adaptively modifying the current command signal and means for controlling the current demanded by the field winding to reduce the torque demanded by the generator at times, inter alia, of acceleration and engine knocking.

摘要： A rotor of a permanent magnet type synchronous motor facing a stator having a number of slots comprises a rotor core fixed to a motor shaft and an even number of permanent magnets in a circumferential direction of the rotor core. Projecting portions are formed in the shape of a protruding portion of the rotor core over each permanent magnet. The width (A) of each projecting portion is different from the pitch (B) of the slots of the stator. A position detector for detecting the permanent magnet position of the rotor comprises detectors of the normal rotation and other detectors of the reverse rotation. These detectors are arranged having predetermined phase differences (.alpha., .beta.) to a center line. A pattern generating circuit is provided for switching the conducting position to the stator winding corresponding to the phase differences.

摘要： A crank angle sensor comprises a magnetic recording medium rotating synchronously with crankshaft on which data is magnetically recorded and a magnetic sensor spaced apart from the magnetic medium and detecting the signals to produce rotational angle information. The magnetic recording medium is divided into plural tracks including an angle track and a cylinder track. On the angle track, unitary magnetic poles, serving as the magnetically recorded data are provided with a pitch P corresponding to the angle to be detected. The cylinder track contains unitary magnetic poles arranged adjacent those with a angle track in the pitch P and at locations which are determined by the number of cylinders of the engine. The polarities of the unitary magnetic poles on the cylinder track are the in same arrangement as those of the unitary magnetic poles of the angle track. No magnetic interference occurs between the unitary magnetic poles of the angle track and three of the cylinder track, so that angle signals and cylinder signals can be obtained with high accuracy.

摘要： A permanent magnet electric machine such as, for example, a motor or generator, including a permanent magnet field member, an armature having salient magnetic poles and armature windings. A greatest common division of the number of magnetic poles of the field member and the salient magnetic poles having the armature windings differs from the number of magnetic poles. A group of grooves is formed between the salient magnetic poles having an interval of 2/3M.pi., with M being an integer which is not a multiple of three. To reduce the occurrence of cogging torque, auxiliary grooves are provided on the surface of the salient poles at positions which are spaced apart from positions of the grooves by (.pi./3)K+(.pi./6), in terms of electrical angle, with K being an integer.
