ELECTRIC MOTOR DEVICE FOR ELECTRIC POWER STEERING AND ELECTRIC POWER STEERING DEVICE

摘要

In conventional electric power steering electric motor apparatuses, fastening and dismantling are facilitated by screws, but because spacing between a controlling circuit and a power supplying portion of an electric motor is wider, connecting terminals that project outward from a controlling circuit toward the electric motor are longer, and one problem has been that connecting positions with a power supply part of the electric motor vary, making assembly difficult. An electric power steering motor apparatus includes: an electric motor including: a stator; and a rotor that is disposed inside the stator; and a controlling unit including: a driving circuit that is connected to the stator to supply electric power; a controlling circuit that controls the driving circuit; and a housing that covers the driving circuit and the controlling circuit, and to which the electric motor can be mounted, wherein: the electric motor and the controlling unit are configured approximately coaxially; the electric power steering electric motor apparatus includes: a power supplying portion that projects outward from the electric motor; and a connecting portion that projects outward from the controlling unit, and that is connected to the power supplying portion; and the connecting portion is held on the housing by means of an insulating member.
