If micro-electronic multipole (here p = 8 pole pairs), permanent-magnet-excited synchronous machines over higher-frequency sinusoidal currents (here to f N = 400 Hz) are guided by means of pulse static frequency changers function of position, then one speaks of " [...] -drives" respectfully today. Your rotational speed can, here to n N = 300/min, are shown adjusted continuously, wherein, especially in [...] fairy-like efficiencies. Until now it is customary, for example, three winding phases of the three-phase motor by series connection of "single tooth coils" interleaved accommodate in a stator stack. Seeking to make, to achieve higher performance, we must provide for insulating class F or H, sometimes obtained also relatively small machines water cooling. Since the ratios are with the considerably more favourable here proposed engines with strand separation. That leaves in which in the following representation of the four per pole pair standard designstand teethtwo-strand engine outlined in which only two per disc wherein strand separation. The space can be used for the respective coil system. It is derived in a conventional construction as compared to a three-phase motor at equal dimensions of the electromagnetically active part this computationally 1.6 kW to about 3 kW from about improve performance. It is a sinusoidal distribution of said memorized Rarely-earth-for the rotor magnetomotive force provided, and the stand is reflected in the overall impact [...] from without, so that... |
