马达及具有马达的散热风扇
摘要：
一种马达，包含一金属基座、一定子及一转子。该金属基座结合一轴接部，该定子结合于该金属基座，该转子包含一轮毂及一永久磁铁，该轮毂可旋转地结合于该轴接部，该永久磁铁与该定子之间具有一气隙；其中，该轮毂与该金属基座之间具有一径向旋转范围，该永久磁铁与该金属基座之间具有一磁吸范围，在该径向旋转范围内，该金属基座设有位于磁吸范围与上述轴接部之间的一透空区，该透空区设有一连接部，该轴接部结合于该连接部；又，该马达可应用于一散热风扇。借助透空区的设计，可有效减轻马达的重量。
摘要（英）：

A motor comprises a metal base, a stator, and a rotor. The metal base combines with a shaft receiver. The stator combines with the metal base. The rotor comprises a hub and a permanent magnet. The hub rotatably combines with the shaft receiver. A air gap forms between the permanent magnet and the stator. Wherein, a radial rotation area forms between the hub and the metal base. A magnetic area forms between the permanent magnet and the metal base. In the radial rotation area, the metal base has an empty region between the magnetic area and the shaft receiver. The empty region has a connecting portion combined with the shaft receiver. In addition, the motor can be applied to a dissipation fan. It can reduce the weight of the motor by setting the empty region.
