Abstract
Research objective of this article is the ultimate mechanical characteristics estimation of the traction motor electric transmission of the vehicle by example of car. The author pointed parameters required for the calculation ofthe limit mechanical characteristics. In the article, the author gives basic types of electric motors used as traction motor: DC motor, asynchronous motor with squirrel cage rotor, synchronous motor with permanent magnet and switch reluctance motor. Main advantages and disadvantages of traction electric motor used for electric transmission of vehicle are given. The author give forces acting on the vehicle. The traction balance based on these forces are given. The author justifies, that the best of curve type of ultimate of mechanical characteristics is the hyperbole. The author proposes to calculate the key points of hyperbole in accordance with operational parameters. The driving cycles, used for determining of fuel consumption and power reserve, are discussed in the article. The author considers it necessary to use modern test driving cycle WLTC for calculate of mechanical characteristics of traction electric motor for determine some parameters of vehicle and main mechanical characteristics of electric traction motor.
