Abstract: A motor includes a stator that has pole cores and a stator coil comprised of unit coils each being concentratedly wound around a corresponding one of the pole cores. Each of the unit coils is comprised of first and second sub-coils that are stacked in two layers in a stacking direction. Each of the first and second sub-coils is spirally wound so that coil sides of the sub-coil overlap each other in an overlapping direction perpendicular to the stacking direction. Each of the unit coils also has, at a single place, a connecting portion that connects the first and second sub-coils of the unit coil. The connecting portion is provided in a coil end of the unit coil. For each of the first and second sub-coils of the unit coil, the connecting portion is located at an innermost periphery of the sub-coil in the overlapping direction of the sub-coil.

Abstract: An engine starting apparatus is equipped with a starter which, when it is required to start an engine, moves a pinion to establish engagement with a ring gear coupled to the engine and energizes an electric motor to produce and transmit torque to the ring gear through the pinion for cranking the engine. When the rate of decrease in current flowing in the electric motor or the rate of rise in voltage appearing at a terminal of the starter or a power supply for the electric motor exceeds a given value after the engine starts being cranked, the engine starting apparatus works as a firing-up determiner to determine that the engine has been fully fired up.

Abstract: A starter includes a coil spring disposed between a pinion gear and a motor and a buffer rubber disposed between the pinion gear and the coil spring. When the pinion gear is subjected to a reactive force from an engine, the buffer rubber absorbs the impact. Before the impact acts on the pinion gear, the coil spring is subjected to a given initial load. When the impact acts on the pinion gear, the coil spring absorbs it transmitted through the buffer rubber. The cover in which the coil spring is stored has a flange which is held from moving to the pinion gear in response to expansion of the coil spring, while it is permitted to move to the motor in response to contraction of the coil spring. This eliminates a risk that mechanical noise occurs when the pinion gear is advanced and then brought into mesh with the engine.

Abstract: A DC motor includes a cylindrical yoke constituting a magnetic path, pole cores fixed to an inner periphery of the yoke so as to be arranged at even intervals along a circumferential direction of the yoke, and a field conductor that generates a magnetic field to magnetize the pole cores when supplied with a current. The field conductor includes inter-core conductors each of which extends in an axial direction of the yoke so as to be disposed between circumferentially adjacent pole cores. Each of the inter-core conductors is formed by integrating a first conductor part that generates a magnetic field to be applied to one of the circumferentially adjacent pole cores and a second conductor part that generates a magnetic field to be applied to the other of the circumferentially adjacent pole cores.

Abstract: An apparatus for starting an engine, including an inertia-engagement-type starter. In the apparatus, a starter-characteristic switching mechanism is configured to switch an output characteristic of the starter between a plurality of output characteristics including at least a low-torque high-speed characteristic and a high-torque low-speed characteristic, where the output characteristic of the starter is hereinafter referred to a starter characteristic. A timing controller is configured to control when the starter-characteristic switching mechanism switches the starter characteristic such that the starter characteristic is set to the high-torque low-speed characteristic from initiation of actuation of the starter at least until a pinion successfully meshes with a ring gear, and after the pinion has successfully meshed with the ring gear, the starter characteristic is switched from the high-torque low-speed characteristic to the low-torque high-speed characteristic at which the engine is cranked by the starter.
