Application of Speed Estimation Techniques for Induction Motor Drives in Electric Traction Industries and vehicles
Induction motors are the most commonly used in the traction industries and electric vehicles, due to their low primary cost, low maintenance costs, and good performance. Speed identification is needed for the induction motor drives. However, using of speed sensors in the induction motor drives is associated with problems such as, extra cost, reduced reliability, added mounting space, etc.. Ther...
متن کاملSensitivity Analysis of Characteristic Parameters of Railway Electric Traction System
The modal analysis, which decouples the contact wire and rail track conductors, is used to develop an integrated model of single rail track and contact wire. The characteristic impedance and propagation constant matrices of integrated model have been computed. The authors have studied effects of various parameters of interest on characteristic impedance and propagation constant using sensitivit...
متن کاملElectric Traction for Automobiles – Comparison of Different Wheel-hub Drives
In this paper, a comparison concerning electric traction drives for passenger cars is given. Electric traction drives presently available on the market are analyzed and future developments are described. Two main classes of such drives are presented: centre drives (like presently known from hybrid cars) and wheel-hub drives (which are still in the research and development phase). The wheel-hub ...
متن کاملExperiment System of Motorcycle Impact Injury Using Electric Motor Traction
Although motorcycle crash is one of the most common causes of death and injury, there hasn’t been a standard experiment system to simulate the generation of the resulting motorcycle impact injuries. A unique motor drive unit (MDU) and motorcycle crash simulation unit (MCSU) were developed to establish a short-track and high-accuracy experiment system of motorcycle impact injury. The control har...
متن کاملTraction control of an electric formula student racing car
This article describes the design of a traction control system in an electric Formula Student vehicle. In many race applications the accelerator pedal is difficult to control for an in-experienced driver, especially in the case of electric vehicles, where a large torque is available from standstill. A 3-DOF driveline model is used in combination with a 7-DOF vehicle model and a non-linear tyre ...
