    Abstract: A curved stator module and a magnetic drive conveying system are disclosed. The curved stator module includes a curved stator, which has a curved stator body and a curved armature winding arranged on the body. The curved armature winding includes an avoidance portion and an arc-shaped curved portion. The avoidance portion has a first end, a second end, a first inner side surface, and a first outer side surface. The arc-shaped curved portion includes a second inner side surface and a second outer side surface. The first end splices with a linear armature winding of a linear stator module. The first inner side surface connects to the second inner side surface. The second end splices with the arc-shaped curved portion. The first inner side surface extends obliquely from the first end toward the second end and the first outer side surface.
