Mass-dimensional Parameters of Traction Drive

AbstractA traction electric drive is used for an industrial tractor. The motor consists of a generator, a controlled rectifier, autonomous inverters, and two onboard motors. The key feature of the introduced electric drive is the use of field regulated independent excitation reluctance machine as a generator and traction motors. These electric machines have the following performance specifications: the generator and motor design is brushless; and simple, the rotor has high mechanical stiffness that increases reliability at high rate and overloads. There are no turns on the rotor; the motor is designed for simplicity of manufacture. The drives have increased effectiveness in terms of the effect of a “cold” rotor frame; the motors have high torque overloads power (up to 4-6 times the values of nominal torque). The turns of the motor and the generator are one- layered with full pitch capability of current and voltage. The drive manipulation is based on the transistors. The interval of the torque regulation is 1:10 resulting in permanent power for the drive [1]. This motor is used not only as a traction drive, but because of the simplicity of a frame it may be used for other devices where high load working cycles are required for operation
