Abstract
A compact motor capable of being reflow-soldered, which can solve a problem of thermal demagnetization of a magnet with a simple structure, has magnets in a housing. At least a part of a surface to which the magnet is attached is separated by an acrylic adhesive sheet and heat resistant resin from metal members, such as a bracket and shaft forming part of the housing. The shaft is stainless steel having a low heat conductivity or an additional cover is used for the shaft to withstand reflow-soldering.
