The invention discloses an elevator traction machine with a magnetic encoder. The elevator traction machine comprises a machine base, a rotor, a fixed main shaft, a magnetic encoder assembly, a shaft system sealing assembly and a housing assembly. The magnetic encoder assembly comprises a magnetic ring, a magnetic head, an encoder signal cable, a magnetic ring mounting piece, a magnetic head mounting seat and a magnetic head mounting piece; the shafting sealing assembly comprises a bearing, a bearing limiting device, a first sealing ring and a second sealing ring. The outer ring of the first sealing ring is mounted on the rotor in a tight fit manner, and the inner ring is in contact with the fixed main shaft; the outer ring of the second sealing ring is installed on the rotor in a tight fit mode, the inner ring of the second sealing ring makes contact with the magnetic head installation piece, and the housing assembly is installed on the outer side of the magnetic encoder assembly and used for preventing dust and grease in a well from entering the magnetic encoder assembly. The problem that machine-room-free civil engineering arrangement limits the thickness size of the traction machine can be solved, meanwhile, maintenance personnel can conveniently conduct daily maintenance in a hoistway, the structural design is reasonable, the space is compact, and reliability is high.
