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.

Electric traction drive of an agricultural tractor

IOP Conference Series: Earth and Environmental Science, 2020
Abstract In the article, the task of expanding the range of work in speed and moment of traction electric drive of an agricultural tractor is considered. We propose to achieve this goal through the use of a two-stage gearbox based on a three-row planetary gear. It is proposed to shift gear ratio by eliminating one row of the gearbox from
