Abstract

1480837 Winding layouts for linear motors BBC BROWN BOVERI & CO Ltd 1 July 1974 [5 July 1973] 29169/74 Heading H2A A linear motor winding has every even numbered coil group omitted up to the (m - 1)<SP>th</SP> group and reconnected in the same order, phase and polarity at the end of the winding spaced by q slots from the last occupied slot, where p is the number of pole pairs, m is the number of phases and q is the number of slots per pole per phase. In the three-phase, four-pole machine shown, there are two slots/phase in each pole. In the group of twelve coil groups therefore, the second (m - 1)<SP>th2</SP> group is detached and reconnected at the end of the winding spaced by two slots (q). Since the winding shown is twolayer, slots 3, 4 thus become emptied and slots 8, 9 lose one conductor each. These are reconnected to the winding in slots 27, 28 and 32, 33 respectively and the phase windings are also rearranged, whilst retaining the same energization in the unchanged slots. The empty or half-empty slots are preferably filled with ferromagnetic material.
