Electric vehicle (EV) is one of the effective solutions to control emission of greenhouses gases in the world. It is of interest for future transportation due to its sustainability and efficiency by automotive manufacturers. Various electrical motors have been used for propulsion system of electric vehicles in last decades. In this paper brushed DC motor, Induction motor (IM), switched reluctan...
Since permanent magnet direct current (DC) motors are mainly used in various industrial automation applications, the demand for electric is increasing rapidly. However, mass production of motors, often, only random inspections to check specifications and performance motors. For manufacturing or engineering application staff have a more thorough understanding characteristics motor, it necessary ...
We study the traffic of two types of molecular motors using the two-species asymmetric simple exclusion process (ASEP) with periodic boundary conditions and with attachment and detachment of particles. We determine characteristic properties such as motor densities and currents by simulations and analytical calculations. For motors with different unbinding probabilities, mean-field theory gives ...
Current Developments and Challenges in the Recycling of Key Components of (Hybrid) Electric Vehicles
The introduction of electromobility causes major challenges as new components and materials enter vehicle recycling. This paper discusses the current developments in the recycling of traction batteries, electric motors, and power electronics, which constitute the key components of (hybrid) electric vehicles. Both technical and ecological aspects are addressed. Beside base metals, all components...
In order to manufacture smaller and more efficient electric motors an accurate prediction of the motor thermal performances at the design stage is a necessity. In addition, the thermal performance often needs to be analyzed when a motor is used in a different way to which it was originally designed for. An important example is the use of variable speed drives with induction motors designed for ...
Herein is reported development and testing of a life cycle analysis (LCA) procedure for assessing the environmental impact of induction motors. The operating conditions of a given industrial application are defined by the mechanical power required, operating hours and service life of the three-phase induction motor involved. Based on manufacturer’s data mainly, different three-phase induction m...
An electric vehicle (EV), otherwise called as an electric drive vehicle uses one or more electric motors or traction motors to create the driving force needed for motion. Considering the power supply for vehicle computer and electronics, battery and DC-DC converter is required. To achieve the required voltage levels, power converters and inductances are required. Resonant converters are popular...
For the past two decades, Brushless DC motor has become more efficient and robust motor in industrial applications due to their simplicity in structure, reliability, good mechanical properties. The absence of brushes features these motors similar to AC motors whereas their speed performance is nearly equal to that of the DC motors. Thus the combined advantages of AC and DC motors make these mot...
Accurate model identification and fault detection are necessary for reliable motor control. Motor-characterizing parameters experience substantial changes due to aging, motor operating conditions, and faults. Consequently, motor parameters must be estimated accurately and reliably during operation. Based on enhancedmodel structures of electric motors that accommodate both normal and faulty mode...
Demonstrators and research projects about electric aircraft taxi systems testify the current interest in lowor zero-emission ground propulsion technologies to lower the overall fuel consumption and emissions of commercial flights. Electric motors fitted in the main landing gears are one of the most promising layouts for these systems especially for narrow-body commercial aircraft. From a contro...
