The fixed impeller comprises: an impeller plate (131); and at least two blades (132) arranged in a spiral shape on the periphery of the impeller plate, wherein an air guide channel is defined between two adjacent blades, inner ends of the blades are fixedly connected to the periphery of the impeller plate, sealing portions (133) are formed at outer ends of the blades, and the sealing portions are in interference fit with a shell or an air gathering cover of the electric motor. The electric motor has the beneficial effects of it being ensured that the fixed impeller and an air gathering cover or the shell are in an interference assembly state, the fixed impeller is relatively easy to assemble, is less prone to getting stuck or breaking, and has a good sealing effect, thereby not only solving the problem of a surge during traditional clearance fit, but also solving the problem of assembly during interference fit.
