摘要： PROBLEM TO BE SOLVED: To provide an electric power steering device 1 which is miniaturized with the wiring simplified, and at the same time, with a reduction in electric wave noises, and of which the reliability is high.
SOLUTION: In this EPS 1, a control circuit 9, an electromagnetic clutch and a steering angle sensor are integrated with a motor and housed in one motor housing 10. The motor housing 10 comprises an end frame 11 to which respective constituent parts are attached, and a cup-shape motor case 12 which is airtightly attached to the end frame 11, and the end frame 11 is fixed to a rack housing 13 of a steering mechanism. The motor and the control circuit 9 which are main heating parts among respective constituent parts, are respectively attached to the end frame 11 made of aluminum in a manner to radiate heat, and the heat transmitted to the end frame 11 is discharged into air by being further transmitted to the rack housing 13.

摘要： PROBLEM TO BE SOLVED: To reduce the change rate of a magnetic reluctance by a simple slot structure and suppress a torque ripple. SOLUTION: An armature core 5 has a plurality of approximately V-shaped slots 51 which are extended in a direction parallel with an armature shaft 4, partition walls 52 which separate the slots 51 from each other, and 1st and 2nd rims 53 and 54 which protrude in the circumferential direction from both the sides of the tip parts (a) of the partition walls 52. The 1st inclined part 53a of the 1st rim 53 of the partition wall 52 is approximately parallel with the 2nd inclined part 54a of the 2nd rim 54 of the adjacent partition wall 52 and, further, the 1st inclined part 53a and the 2nd inclined part 54a face each other partially.

摘要： PROBLEM TO BE SOLVED: To provide an electric motor power steering system in which the assembling work is facilitated by decreasing the number of components and the labor for assembling. SOLUTION: A control circuit 9 is disposed on the side of a motor in a motor housing with two brush holders 23 being secured integrally to an outer case 9b for holding a board 9a. Two brush holders 23 are constructed such that the center lines A, B of a brush inserting section pass through the central axis O of an armature while making an angle of 90 deg. (i.e., two brushes 22 are disposed at an interval of 90 deg. in the circumferential direction of a commutator 21). The motor wiring connecting the control circuit 9 and the brush 22 is realized by connecting an intermediate terminal 43 provided on the outer case 9b with each switching element 33 arranged on the board 9a by means of a bonding wire 44 and connecting a spring 45 contained in the brush holder 23 with the intermediate terminal 43.

摘要： PROBLEM TO BE SOLVED: To provide an electric motor reducing a cost further with rotating switchable of an output shaft without performing switching of a current in an electric motor. SOLUTION: When an armature 30 is rotated in a direction of arrow mark C (left hand turn), this rotation is transmitted to a first gear part 91 of a planetary gear 90 through an armature shaft 40 and a sun gear 42. Since a clearance is generated between a second contact member 210 and a flange part 204 of a rotation maintaining unit 200, it is prevented from rotation regulation relating to a housing 80, and since rotation is regulated relating to the housing 80 in an internal gear 110, the planetary gear 90 is rotated on its own axis of the periphery of a pin 73, also rotated in a right hand turn of the periphery of the armature shaft 40, so as to decelerate rotating of the armature shaft 40, an output shaft 70, as shown by arm arrow mark D, can be rotated in the same direction (left hand turn) to a direction of rotation of the armature shaft 40. By rotating this output shaft 70, steering is assisted.
