The invention discloses a high-stability centrally-mounted motor adopting a planetary reducing mechanism. The high-stability centrally-mounted motor comprises a shell, a movement, the planetary reducing mechanism and a crankset positioning sleeve, wherein a middle shaft penetrates through the lower part of the shell; the movement, the planetary reducing mechanism and the crankset positioning sleeve are arranged in the shell; a core shaft of the machine core is connected with a planetary speed reducing mechanism, a planetary output wheel is fixedly or integrally arranged at the front end of a planetary carrier of the planetary speed reducing mechanism, a small gear is coaxially arranged on the planetary output wheel, and the small gear is meshed with a large gear sleeved on a crankset positioning sleeve through a one-way clutch. The chain wheel positioning sleeve is sleeved on the middle shaft, and the front part of the chain wheel positioning sleeve extends out of the shell to fix the chain wheel; the device is characterized in that a planet carrier is supported on a mandrel through a planet carrier bearing, the front part of the mandrel extends into the planet carrier to form a cantilever shaft, and a sun gear is arranged on the cantilever shaft and is meshed with a plurality of planet gears arranged in the planet carrier; and a central shaft which is coaxial with the central shaft is arranged on the planetary output wheel, and the central shaft is assembled in the shell through an output wheel bearing. The motor is better in operation stability, lower in noise, higher in working reliability and easy to assemble.
