Abstract
The utility model relates to a radial wirewound stator structure composed of a single magnetic pole sheet and a coil, wherein the magnetic pole sheet is provided with a central hole, the axial direction of which is provided with a shaft tube. The radial direction of the central hole is provided with a plurality of pole arms extending in a radiation shape. The coil is wound around the pole arms, and a magnetic pole surface is curved and extended on one end of the pole arm and is vertical to the pole arm. A stator magnetic pole sheet and the permanent magnet of a rotor have good magnetic induction which can generate better repulsion force to drive the rotor to rotate. The central hole of the single stator magnetic pole sheet is provided with a shaft tube which can make an entire stator conveniently positioned and combined. Thus, the radial wirewound stator can be conveniently and quickly processed and manufactured to reduce cost.
