A magnetic element holder () of an electric motor has a carrier formed as a frame structure. The carrier has at least one receiving section () to receive at least one magnetic element (). The carrier is configured with a holding device () for positionally fixed holding the at least one magnetic element () inside the at least one receiving section (). The magnetic element holder () is configured to be fastened to a rotor () of an electric motor.

A fan housing includes a housing body for accommodating fan components and an outer casing which surrounds the housing body in circumferential direction. The housing body has at least two webs extending in a circumferential direction on the radial outer side. The outer casing has at least two ribs extending in the circumferential direction on the radial inner side. The ribs, in the assembled state, between the housing body and the outer casing, form a channel circulating in the circumferential direction for receiving and holding a heating band. The outer casing has at least one guiding rib directed in the radial direction toward a housing body as well as into the channel and extending in the circumferential direction.

Fan housing having a heating band channel

The invention concerns a housing of a fan with an external covering, wherein the housing comprises a housing body to accommodate fan components, and a radial exterior face of the housing body is surrounded by the external covering in the circumferential direction over its full surface, so that a radial exterior surface of the housing is formed by an exterior surface of the external covering, and the external covering is detachably fastened to the housing body.

The invention relates to a flow rectifier for an axial fan as well as to an axial fan having a flow rectifier. A flow rectifier according to the invention for an axial fan with a hub and at least one vane is characterized in that the at least one vane can be operatively connected to the hub so as to be detachable. Since the vane and the hub can be connected so as to be detachable, the flow rectifier has a modular structure.

Flow straightener

A housing for a fan or blower, in particular an axial fan, includes a wall ring () having an inlet nozzle section (), an outer diffuser () having an inlet flow opening () and an outlet flow opening (), and a holder for an electric motor () of the fan. The holder is arranged in an inner space of the housing. The outer diffuser () is formed by at least two partial ring sections that are connected to the outer circumferential surface via mechanical connection elements. The holder includes several struts () that are fastened to an inner circumferential surface of the outer diffuser () by one end, are circumferentially spaced apart, and are fastened in the edge region of the inlet flow opening (). The struts can be installed by their other end to a motor flange () of the motor housing () of the electric motor ().
