Title: Two-pole async. motor with reduced cooling fan noise - uses blades on both rotor ends with diameters smaller than rotor diameter
Inventor: KIRCHENMAYER GEORG DR ING
IPC: H02K9/06
Filed: 1973-09-19
Abstract: The two-pole asynchronous motor has the noise of its internal cooling fan reduced by making the fan blades diameter smaller than that of the rotor and by sloping the stator winding ends in the region of the blades away from the rotor assembly. The fan blades are mounted on each of the rotor core end faces and having a smaller diameter than the rotor core diameter. The ends of of the stator windings in the regions of the two sets of fan blades slope away from them with a gradient of 0.2 to 0.04 mm/mm. The two sets of blades are joined by metal shorting rings. Alternatively the shorting rings themselves may form the fan blades.
