Abstract
An electric motor to be easily assembled while taking the advantages of a retrofitted electric motor, excellent maintenance performance and no fear of damage in a temperature sensitive device due to resin injection pressure. The electric motor includes an electric motor shaft, a rotor, a stator, a housing, a sealing body formed of sealant to cover a coil end of the stator, a temperature sensitive device, an end cover, and a resilient retaining member. The electric motor shaft passes through the end cover. The sealing body includes a temperature-sensitive-device support surface opposed to the end cover. The temperature sensitive device is retained between the end cover and the temperature-sensitive-device support surface while the retaining member is interposed between the temperature sensitive device and the end cover.
