Mechatronic Modules of Traction Electrical Drive

Abstract

An overview of new solutions in the field of traction electric drive is given: integrated starter-generator system, electrically controlled transmission system. Such systems relate to mechatronics for a number of reasons: the integration of several devices in one (starter and generator, mechanical and electromechanical converter), the management of several power flows simultaneously, increased reliability requirements, mass dimensions, control range, including in the second quadrant, the magnitude of the overload torque, increased requirements for the control system. The key element of the starter-generator system is the electromechanical converter, therefore advantages and disadvantages of new traction electric machines for AC drives are given. A key element of the electrically controlled transmission system is the power splitter, which can be mechanical, magnetic planetary gears and electric machines in two rotary versions. The composition and functions of the system, its advantages, disadvantages and prospects are given. It is shown that an electric drive with a field regulated reluctance machine possesses the qualities necessary for constructing the systems under consideration.
