Abstract

The distribution of the wave voltage on the 4A series engines with a rotation axis height of 90 mm with an amplitude of rectangular pulses of 50 V, a front of 1-7.5 ?s and a duration of 400 ?s was investigated. The largest relative inter-joint voltages (MCN) occur on the first coil and reach 0.4- 0.5 In circuits with a grounded neutral, after reflection of a wave from a neutral, significant MCS appear on the last coil: they are close to or equal to the MCS on the first coil. The magnitude of the MCN of the first coil depends on the test circuit for switching the phases of the windings: the greatest values ??of the MCN are obtained when a wave is incident on one phase of a winding with an open or closed neutral. to a groove. After 0.1-0.2 ?s after a wave was dropped, an uneven distribution of voltage across the turns of the first coil was detected.
