摘要：
A split stator for an electric motor includes a core having a tooth portion, a coil formed around the tooth portion, insulation spacers arranged between a surface of the tooth portion and an inner periphery of the coil, and holding the inner periphery of the coil with a space kept from the surface of the tooth portion, and a resin filler material having high thermal conductivity and filling the space. The resin filler material is configured to allow heat release from the inner periphery of coil to the core.
