<p>The a.c. synchronous motor has an outer rotor and coaxially positioned stator coil. The stator is provided with an induction section consisting of a coil and a coil casing of iron and iron pole connections. The connections spread out and run towards the periphery, to envelope the squirrel cage. The stator has a second spool and the rotor has an outer ring-pole-surface and an inner ring pole surface. The generated magnetic field's lines of force pass via the pole connection pieces and the casing through the coil in the rotor. In one design the stator has a disc and the rotor cylinder, at its edge, has a corresp. row of pole teeth. The pole-teeth cylinder is only provided with pole-teeth in the gaps between the stator and inter-sections.</p> |
