Zusammenfassung:A MINIATURE ELECTRIC MOTOR HAVING PERMANENT MAGNETS (2) MOUNTED ON AN INNER CIRCUMFERENTIAL SURFACE (11) OF A CASING (3), A ROTOR (4) ROTATABLY SUPPORTED IN AN INTERIOR (21) OF THE CASING, AND A COMMUTATOR (14) OF THE ROTOR AND BRUSHES (16) WHICH ARE PROVIDED IN THE INTERIOR OF THE CASING AND ARE IN SLIDING ENGAGEMENT WITH EACH OTHER. THE MOTOR IS THUS PRODUCED IN WHICH ATMOSPHERIC CONSTITUENT AGENTS COMPOSED OF A KIND OR PLURAL KINDS OF DIESTER CARBONATES ARE SEALED IN THE INTERIOR OF THE CASING. THUS, A CONTACT RESISTANCE BETWEEN THE COMMUTATOR IN THE CASING INTERIOR (21) AND THE BRUSHES IS REDUCED AND THE MOTOR PERFORMANCE IS STABILIZED. AT THE SAME TIME, IT IS POSSIBLE TO SUPPRESS ANY WEAR OF THE SLIDING PORTIONS AND TO PROLONG A SERVICE LIFE OF THE MOTOR.
