To provide a worm-drive geared motor that is reduced in size in the direction of a longitudinal axis of a rotation shaft and is optimized in cooling.SOLUTION: A geared motor includes: an electric motor (2) comprising a rotor (20) including magnetic elements, a stator (21) having electromagnetic excitation windings for the rotor, a rotary shaft (22) rigidly connected to the rotor, and a worm screw formed on the rotary shaft; a worm wheel meshing with the worm screw and connected to an output shaft (8); bearing means (23, 24) for guiding the rotary shaft in rotation with respect to a casing (4); a determination device for determining an angular position of the rotor, the determination device including a multi-pole magnet (5) rigidly connected to the rotary shaft (22); and at least one heat sink (7) on the rotary shaft, which projects radially from the rotary shaft. A peripheral surface of the heat sink is oriented to a tangential direction of the worm wheel.SELECTED DRAWING: Figure 1

    【課題】回転シャフトの縦軸線方向に小型化するとともに、冷却を最適化したウォーム駆動ギヤードモータを提供する。【解決手段】磁気要素を含む回転子(20)、回転子の電磁励起巻線を有する固定子(21)、回転子に剛体的に連結された回転シャフト(22)及び回転シャフトに形成されたウォームねじとを備える電気モータ(2)と、ウォームねじと噛合い出力シャフト(8)に連結されたウォームホイールと、回転シャフトをケーシング(4)に対して回転で案内するための軸受手段(23、24)と、回転シャフト(22)に剛体的に連結された多極磁石(5)を含む、回転子の角度位置を決定するための決定装置と、回転シャフトに回転シャフトから半径方向に突出する少なくとも1つのヒートシンク(7)を備える。ヒートシンクの周面はウォームホイールの接線方向に向けられている。【選択図】図1
