The invention relates to a magnetic dynamic seal inner rotor hub motor structure. The structure comprises an inner rotor bracket (4) and a hub bearing outer ring (5a), and the inner rotor bracket (4)and the hub bearing outer ring (5a) are coaxially and fixedly connected with a rim (2) in sequence; a hub bearing inner ring (5b) is installed in the hub bearing outer ring (5a), the hub bearing innerring (5b) is coaxially and fixedly connected with the outer stator shell (3b), the outer stator shell (3b) is connected with a cover plate (3a), and a magnetic sealing ring (6) is arranged at the position, close to the axis of the hub bearing inner ring (5b), between the cover plate (3a) and the inner rotor bracket (4). Compared with the prior art, according to the invention, the hub bearing outer ring, the inner rotor bracket and the rim are coaxially and fixedly connected, the electronic components are integrally installed on the stator shell, the wire harness and the cooling pipeline are led out, the integration degree of the whole hub motor is improved, in addition, the magnetic sealing ring is arranged at the position, close to the axis of the motor, between the cover plate and the inner rotor, and the dynamic sealing reliability can be effectively improved.
本发明涉及一种磁力动密封内转子轮毂电机结构,包括与轮辋(2)依次同轴固联的内转子支架(4)和轮毂轴承外圈(5a),其中,轮毂轴承外圈(5a)内安装有轮毂轴承内圈(5b),轮毂轴承内圈(5b)与外定子壳体(3b)同轴固联,外定子壳体(3b)连接有盖板(3a),盖板(3a)与内转子支架(4)之间靠近轮毂轴承内圈(5b)轴线的位置设有磁力密封圈(6)。与现有技术相比,本发明通过将轮毂轴承外圈、内转子支架和轮辋同轴固联,在定子壳体上集成安装电子元器件并引出线束和冷却管路,提高了整个轮毂电机的集成程度,此外,本发明在盖板与内转子之间靠近电机轴线的位置设置磁力密封圈,能够有效提升动密封可靠性。
