<p>Axial flux rotary micromotor and local forced-air cooling device has a flat, ring stator (2) with stator coils (12) and one or two flat, ring shaped, squirrel cage rotors (3). A thin sliding bearing (8) is positioned between active stator and rotor surfaces. The axial flux micromotor has a very small air gap (G1/G2) between active stator and rotor surfaces, which enables increased micromotor power per mass unit. The axial flux micromotor incorporates into a very compact, local forced air cooling device under the principal 'motor outside-fan inside', i.e. the fan blades are secured to the rotor rings. The axial flux micromotor is constructed without a central shaft and provides more homogeneous air flux density on cooled electronic components.</p> |
