Abstract:
An electric motor comprising a stator with bearings for rotatably receiving a shaft, and with coils of electrically conducting wire for generating a magnetic field in the stator when an electrical current runs in the coils, each of said coils having a first wire end electrically connected to a first electrical terminal for the motor and a second wire end electrically connected to a contact face of its own, a rotor with a shaft which carries a permanent magnet, said shaft being arranged rotatably in the bearings of the stator such that the magnet cooperates with the magnetic field from the coils, said rotor carrying a contact brush with a first part in sliding, permanent electrical contact with a second electrical terminal for the motor, and a second part in sliding, alternating electrical contact with the contact faces by rotation of the rotor, characterized in that the second part of the contact brush is in sliding, permanent electrical contact with the second electrical terminal through the shaft which is electrically conducting and a bearing which is also electrically conducting.
