Patent
·
OSTI ID:1531375
An electric motor is provided for use in an electromechanical transmission that utilizes automatic transmission fluid. The electric motor includes a stator and a rotor. The rotor includes a plurality of permanent magnets can include magnetic particles coated with hydrogen impermeable material. According to an alternative embodiment, the entire permanent magnet or the rotor itself can be coated with hydrogen impermeable material. According to a further alternative embodiment, the permanent magnet particles can be secured by a binder that includes a hydrogen storage compound that prevents hydrogen from affecting magnetic properties of the permanent magnet.
