A rotary motor stator includes a plurality of stator teeth and a plurality of terminal securing blocks. The stator teeth are arranged in a ring to define a rotor accommodation space. Each stator tooth includes an inner side, a winding section and an outer side. The inner side is closer to the rotor accommodation space than the outer side, and the winding section is located between the inner side and the outer side for winding a coil. Each terminal securing block is fixed to the outer side of each stator tooth, and each terminal securing block includes a first wire slot configured to secure an end of the coil. An angle between a line passing through a center of the ring and a center of each terminal securing block and a lengthwise direction of the first wire slot is an acute angle.
