Novel flame -proof electric motor rotor

The utility model provides a pair of novel flame -proof electric motor rotor, rotor body include rotor groove, ventilation hole, keyway, rotor tooth portion, rotor yoke portion. Every rotor groove is the chute, becomes 8 degrees with rotor axis, and the shape in rotor groove is similar to triangle -shaped, and the even distribution in ventilation hole is in rotor yoke portion, and the keyway can let rotor and pivot cooperate, plays the effect of transmission moment of torsion. The utility model discloses simple to operate, reliability height, with low costs to the effectual heat radiation property who strengthens the motor, thus vibrations and the noise that good electromagnetic torque characteristic reduces the flame -proof electric motor obtained simultaneously. 本实用新型提供的种新型防爆电动机转子，转子本体包括转子槽、通风孔、键槽、转子齿部、转子轭部。每个转子槽为斜槽，与转子轴线成8度，且转子槽的形状近似于三角形，通风孔均匀的分布在转子轭部上，键槽能够让转子与转轴相配合，起到传递扭矩的作用。本实用新型安装方便、可靠性高、成本低，并且有效的增强了电机的散热特性，同时获得了良好的电磁转矩特性从而降低防爆电动机的震动和噪声。
