1. A rotary motor stator comprising:
a plurality of stator teeth arranged in a ring to define a rotor accommodation space, wherein each stator tooth comprises 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;
a plurality of terminal securing blocks, 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; and
a metal ring frame accommodating the ring of the stator teeth,
wherein 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,
wherein a gap is formed between each terminal securing block and the metal ring frame.
