A rotor assembly being an injection molded piece, and comprising a first shaft sleeve and a rotor; a first injection molded body is formed by using the rotor and the first shaft sleeve as injection molding inserts to pass through injection molding; a second injection molded body is formed by at least using the first injection molded body as an injection molding insert to pass through injection molding; the second injection molded body comprises a lower cover plate and a wrapping layer, the wrapping layer wrapping around at least a portion of the outer peripheral surface of the first injection molded body; the rotor assembly further comprises blades, the blades being fixedly connected to the lower cover plate or the blades forming an integrated structure with the lower cover plate.

Fabrication method for rotor assembly

A controller for vehicle air conditioner includes a base defining a mounting cavity; a knob assembly rotatably mounted to the base, wherein at least a portion of the knob assembly is located in the mounting cavity; and at least one bearing element arranged between the base and the knob assembly. Such a design reduces the friction between the base and the knob assembly and thus reduces the noise.
