ABSTRACT:
A molded motor is provided that allows for ready installation of a heat-conducting member therein and is capable of improving dissipation of heat generated from the stator. The heat-conducting member is integrally formed with a load-side end bracket. The heat-conducting member includes a stopper surface that contacts an end surface of a stator core in the axial direction of a shaft, and an extended portion extending from the stopper surface toward a non-load-side end bracket to contact an outer peripheral surface of the stator core. The heat-conducting member is embedded in a molded portion with the stopper surface contacting the end surface of the stator core and the extended portion contacting the outer peripheral surface of the stator core.
