A fan arrangement includes a fan and toothed ring, and a converter motor includes a fan arrangement. The fan includes a base body on which fan blades are premolded, and the fan includes an annular region, which is premolded on the side of the fan blades facing away from the base body. The toothed ring is situated within the annular region, and thus, in particular, is set apart from the base body, and thus, in particular, is set apart from the base body via the fan blades.
