US 2025/0030304 A1 · ELECTRIC MOTOR

Abstract

An electric motor has a stator, a rotor surrounding the stator, a shaft connected to the rotor in a rotationally fixed manner, and a housing. The housing has first and second housing components, which together enclose a motor compartment in which are arranged the stator and the rotor. A cooling channel extends in an interior space surrounded by the stator. A first end of the shaft is arranged in the motor compartment and a second end of the shaft protrudes from the housing. The first housing component has an inner part which protrudes into the stator. In accordance with this disclosure, it is envisaged that an insert is arranged in the interior space surrounded by the stator, which insert, together with the inner part of the first housing component, defines at least one section of the cooling channel.
