Mathematical models analysis for the thermal state of mining trucks traction motors determining

Abstract

The mathematical models analysis for calculation of the thermal state of mining trucks traction electric motors with electromechanical transmission, which undergo intense heat during operation has been conducted. It has been established that the mathematical apparatus that underlies the traditional approaches for determining the electric cars thermal state is not enough to calculate the mining truck traction engines heat due to inability to take into consideration their design parameters and significant changing loads for short periods of time that occur while performing transportation by a dump truck.
