Valve Traction Motors in Vehicle Electric Drive
Izvestiya MGTU MAMI, 2008 A valve traction motor (VTM) is a contactless analogue of a DC traction motor (there is a mechanical collector-brush contact). The VTM with permanent magnet excitation has supplementary advantages: reliable exitation and its loss absence, the possibility of working with 1 or less zero coefficient of power.
