Salient brushless AC (BLAC) permanent magnet (PM) motors are a preferred topology in the rapidly growing area of electric vehicle traction due to their inherent high efficiencies and excellent power densities. In the design of these systems it is important to appraise the motor performance across the entire torque-speed envelope. This paper presents computationally efficient techniques that all...

For the poor working conditions of tractors, single-motor drive tractors usually choose a motor with large parameters, which leads to lower efficiency under low-load conditions. Taking wheeled tractor YTO as research object, driving scheme dual-motor electric was proposed, and main components system were matched. Based on MATLAB/Simulink, model established. On premise meeting dynamic needs trac...

An accurate numerical model, based on multiconductor transmission lines (MTL) able to evaluate the voltage dynamics across the motor bearings and associated currents of an inverter-fed motor is presented. A full three phase stator winding of the wound type of a high power traction motor is considered in the proposed analysis. The different regions of the motor are modeled as suitable connection...

The grouser height and soil conditions have a considerable influence on the tractive performance of single-track shoe. A bin-based research was conducted to assess shoe at different moisture contents clay loam soil. Eight (7.5, 12, 16.7, 21.5, 26.2, 30.7, 35.8, 38%) three heights (45, 55, 60 mm) were comprised during this study. parameters (thrust, running resistance, traction) determined by pe...
