摘要： A starter for an internal combustion engine is provided which includes a pair of angular contact ball bearings used to support an armature shaft. The bearings are disposed close to opposed ends of a core of an armature. The core has disposed thereon coils which define a commutator on one of the ends of the core. One of the bearings is disposed within an inner periphery of the commutator. This structure results in a decreased interval between the bearings, thus ensuring stability in supporting the armature shaft during rotation, which results in decreased mechanical vibrations, magnetic noises, and wear of the bearings.

摘要： A starter includes an electric motor, a pinion gear driven by the electric motor and a magnetic switch having a plunger driven by a magnetic coil. Electric power to be fed to both the electric motor and the magnetic coil is supplied from an on-board battery through a single common input terminal of the starter. The magnetic switch is composed of a main switch through which a full power is supplied to the electric motor and an auxiliary switch through which a limited power is supplied. Upon closing the auxiliary switch, the motor is driven at a low speed and the pinion gear is engaged with a ring gear of the engine. Then, the main switch is closed to thereby crank up the engine with a full power.

摘要： A starter motor has an armature, a commutator and brushes slidably supported by a brush holder, and a magnet switch controls motor operation. A switch supporting member supports the magnet switch and an energization control unit accommodating a bimetal switch having a contact therein. The energization control unit opens its inner contact to shut off the current carried to a magnet switch coil when the temperature of heat transferred via switch supporting member, i.e., the heat of the coil transferred via brushes and a switch yoke, reaches a predetermined temperature, thereby stopping motor operation.

摘要： An electric rotating machine and manufacturing method of the same is provided that can securely press-fit magnetic poles against an inner circumference of a yoke with a cylindrical body. By directly contacting a first and second end portions of the cylindrical body and moving the same relatively, the diameter of the cylindrical body widens in the outer radial direction to press-fit the magnetic poles against the inner circumference of the yoke. Thus, the variation of the inner diameter of the magnetic poles that occurs due to the dimensional error in permanent magnet thickness and inner diameter of the yoke is absorbed by the relative movement of the first and second end portions. This stabilizes the fixing force of the magnet, and allows the magnet to be securely fixed to the yoke without excessive stress on the cylindrical body. Furthermore, the displacement of the magnetic poles can be restricted by bending axial ends of the cylindrical body radially outwardly.
摘要翻译：提供一种电动旋转机及其制造方法，其可以用圆柱体将磁极牢固地压配在轭的内圆周上。通过直接接触圆柱体的第一和第二端部并使其相对移动，圆柱体的直径在外径向方向上变宽，以将磁极压配合到轭的内周。因此，由于永磁体厚度的尺寸误差和轭的内径而产生的磁极的内径的变化被第一和第二端部的相对运动吸收。这就稳定了磁铁的固定力，并且允许磁体牢固地固定在磁轭上，而不会对圆柱体产生过大的应力。此外，可以通过径向向外弯曲圆柱体的轴向端部来限制磁极的位移。

摘要： An electric rotating machine which withstands mechanical and thermal loads applied thereto is provided. Coil arms and coil trunks are provided in roughly parallel orientation to the end faces of an armature core only through insulating rings and insulating spacers. Metal brush is disposed on coil arms constituting a commutator, whereby the overall length of the armature can be remarkably shortened. The coil arms are strongly pressed against and fixed to the side of armature core by a collar, so that the resistance to the centrifugal force can be remarkably improved. A cylindrical ring is circumferentially fitted on the upper coil trunks to prevent radially outward movement of the coil arms due to the centrifugal force. The coil arms disposed in a non-commutator side are made radially shorter than those disposed in the commutator side. Thus, electric resistance of an armature coil is reduced and radial movement caused by the centrifugal force is reduced.
摘要翻译：提供一种承受施加于其上的机械和热负荷的旋转电机。线圈臂和线圈干线仅通过绝缘环和绝缘垫片以大致平行的方向设置在电枢铁芯的端面。金属刷布置在构成换向器的线圈臂上，从而能够显着地缩短电枢的整体长度。线圈臂通过轴环被强力地压靠在电枢铁芯的侧面上，从而能够显着提高对离心力的抵抗力。圆柱形环周向地装配在上部线圈树干上，以防止由于离心力引起的线圈臂的径向向外移动。设置在非整流子侧的线圈臂比放置在换向器侧的线圈臂的径向短。因此，电枢线圈的电阻减小，由离心力引起的径向运动减小。

摘要： An electric rotating machine with a lightweight and low cost yoke which has sufficient durability to be used under high vibration environments. A tubular yoke for electric rotating machine has a pair of lid portions laid on both axial ends of a tubular portion of a yoke. Through bolts for press-fitting the pair of lid portions from both sides tightens and fixes the pair of lid portions to the yoke. Concave portions extending from the outer circumference to the inner circumference are formed axially on the tubular portion. The center where the tightening force of the through bolts is applied is set between the hypothetical extension outer diameter and inner diameter of the tubular portion at the concave portion so that the tubular portion and the lid portions are tightened and fixed.

摘要： In a starter, an electromagnetic switch is mounted to a seating. A lead wire of an exciting coil is led to an outside of a switch case by a coil-leading portion and is connected to a male terminal, which is fixed to the coil-leading portion by welding. The coil-leading portion is integrally provided with an end plate portion of a bobbin around which the exciting coil is wound. The coil-leading portion passes through and projects from a bottom surface of the switch case to the outside. A metal member, in a form of a plate, is insert-molded in the seating. A 50 terminal is provided on an end of the metal member and a female terminal is provided on an opposite end of the metal member. When the electromagnetic switch is mounted to a predetermined position of the seating, the female terminal engages with the male terminal.

摘要： In a magnet switch for a starter, a first contact portion and a second contact portion are connected in parallel between a battery and a motor. The first contact portion makes contact through a resistive component so that the motor starts rotation at low speed. By this, a pinion is pushed in an axial direction by an axial component of splines and brought into mesh with a ring gear in a condition that its rotation is restricted. Thereafter, the second contact portion makes contact in accordance with further movement of a plunger so that electric power is fully supplied to the motor through the second contact portion, thereby starting engine. A fixed contact of the first contact portion is made of a carbon material. The resistive component is provided by the carbon material.

摘要： A magnet switch has a coil of a reduced size and a sufficiently large contact and does not have a rod running through the plunger or the fixed iron core. A flange and a joint are fixed at one end of the plunger. The arm of the flange is connected to a holder via an elastic body. Movable contacts are pushed into the holder to be fixed at one end thereof. When the plunger moves, the flange, the holder, and the movable contacts move somewhat simultaneously to work as a switch.
