  • EV Power Systems (Motors and Controllers)
    EV Power Systems (Motors and controllers) The power system of an electric vehicle consists of just two components: the motor that provides the power and the controller that controls the application of this power. In comparison, the power system of gasoline-powered vehicles consists of a number of components, such as the engine, carburetor, oil pump, water pump, cooling system, starter, exhaust system, etc. Motors Electric motors convert electrical energy into mechanical energy. Two types of electric motors are used in electric vehicles to provide power to the wheels: the direct current (DC) motor and the alternating current (AC) motor. DC electric motors have three main components: • A set of coils (field) that creates the magnetic forces which provide torque • A rotor or armature mounted on bearings that turns inside the field • Commutating device that reverses the magnetic forces and makes the armature turn, thereby providing horsepower. As in the DC motor, an AC motor also has a set of coils (field) and a rotor or armature, however, since there is a continuous current reversal, a commutating device is not needed. Both types of electric motors are used in electric vehicles and have advantages and disadvantages, as shown here. While the AC motor is less expensive and lighter weight, the DC motor has a simpler controller, making the DC motor/controller combination less expensive. The main disadvantage of the AC motor is the cost of the electronics package needed to convert (invert) the battery‘s direct current to alternating current for the motor. Past generations of electric vehicles used the DC motor/controller system because they operate off the battery current without complex electronics.

  • Piezoelectric Inertia Motors—A Critical Review of History, Concepts, Design, Applications, and Perspectives
    Review Piezoelectric Inertia Motors—A Critical Review of History, Concepts, Design, Applications, and Perspectives Matthias Hunstig Grube 14, 33098 Paderborn, Germany; [email protected] Academic Editor: Delbert Tesar Received: 26 November 2016; Accepted: 18 January 2017; Published: 6 February 2017 Abstract: Piezoelectric inertia motors—also known as stick-slip motors or (smooth) impact drives—use the inertia of a body to drive it in small steps by means of an uninterrupted friction contact. In addition to the typical advantages of piezoelectric motors, they are especially suited for miniaturisation due to their simple structure and inherent fine-positioning capability. Originally developed for positioning in microscopy in the 1980s, they have nowadays also found application in mass-produced consumer goods. Recent research results are likely to enable more applications of piezoelectric inertia motors in the future. This contribution gives a critical overview of their historical development, functional principles, and related terminology. The most relevant aspects regarding their design—i.e., friction contact, solid state actuator, and electrical excitation—are discussed, including aspects of control and simulation. The article closes with an outlook on possible future developments and research perspectives. Keywords: inertia motor; stick-slip motor; smooth impact drive; piezeoelectric motor; review 1. Introduction Piezoelectric actuators have long been used in diverse applications, especially because of their short response time and high resolution. The major drawback of these solid state actuators in positioning applications is their small stroke: actuators made of state-of-the-art lead zirconate titanate (PZT) ceramics only reach strains up to 2 . A typical piezoelectric actuator with 10 mm length thus reaches a maximum stroke of only 20 µm.h Bending actuator designs [1] and other mechanisms [2] can increase the stroke at the expense of stiffness and actuation force ([3]; [4] (pp.

The current-to-torque and frequency-to-speed relationships of BLDC motors are linear. BLDC motors may be described as stepper motors, with fixed permanent magnets and possibly more poles on the rotor than the stator, or reluctance motors. The latter may be without permanent magnets, just poles that are induced on the rotor then pulled into alignment by timed stator windings. However, the term stepper motor tends to be used for motors that are designed specifically to be operated in a mode where they are frequently stopped with the rotor in a defined angular position; this page describes more general BLDC motor principles, though there is overlap.

  • Current-Limiting Soft Starting Method for a High-Voltage and High-Power Motor
    energies Article Current-Limiting Soft Starting Method for a High-Voltage and High-Power Motor Yifei Wang 1,2, Kaiyang Yin 1,*, Youxin Yuan 1 and Jing Chen 1 1 School of Automation, Wuhan University of Technology, Wuhan 430070, China 2 Department of Civil and Environmental Engineering, University of Wisconsin-Madison, Madison, WI 53706, USA * Correspondence: [email protected] Received: 17 July 2019; Accepted: 8 August 2019; Published: 9 August 2019 Abstract: Focusing on the starting problems of a high-voltage and high-power motor, such as large starting current, low power factor, waste of resources, and lack of harmonic control, this paper proposes a current-limiting soft starting method for a high-voltage and high-power motor. The method integrates functions like autotransformer voltage reduction–current limiting starting, magnetron voltage regulation–current limiting starting, and reactive power compensation during starting, and then the power filtering subsystem is turned on to filter out harmonics in power system as the starting process terminates. According to the current-limiting starting characteristic curve, the topological structure of the integrated device is established and then the functional logic switching strategy is put forward. Afterwards, the mechanisms of current-limiting starting, reactive compensation and dynamic harmonic filtering are analyzed, and the simulation and experimental evaluation are completed. In particular, the direct starting and the current-limiting are performed by developing a simulation system. In addition, a 10 kV/19,000 kW fan-loaded motor of a steel plant is chosen as the subject to verify the performance of the current-limiting soft starting method.

Progress in the field of power electronics and microelectronics enables the application of induction motors for high-performance drives, where traditionally only DC motors were applied. Thanks to sophisticated control methods, AC induction drives offer the same control capabilities as high performance four-quadrant DC drives. The concept of the application is to create a vector control ACIM driver with speed closed-loop, using a quadrature encoder coupled to the shaft. It serves as an example of a ACIM vector control system design using a Freescale microprocessor with the eTPU.

  • Introduction
    INTRODUCTION. I.1 - Historical review. The history of electrical motors goes back as far as 1820, when Hans Christian Oersted discovered the magnetic effect of an electric current. One year later, Michael Faraday discovered the electromagnetic rotation and built the first primitive D.C. motor. Faraday went on to discover electromagnetic induction in 1831, but it was not until 1883 that Tesla invented the A.C asynchronous motor [MAR 1]. Currently, the main types of electric motors are still the same, DC, AC asynchronous and synchronous, all based on Oersted, Faraday and Tesla's theories developed and discovered more than a hundred years ago. I.1 Introduction. Since its invention, the AC asynchronous motor, also named induction motor, has become the most widespread electrical motor in use today. At present, 67% of all the electrical energy generated in the UK is converted to mechanical energy for utilisation. In Europe the electrical drives business is worth approximately $1.0 Billion/ Annum. These facts are due to the induction motors advantages over the rest of motors. The main advantage is that induction motors do not require an electrical connection between stationary and rotating parts of the motor. Therefore, they do not need any mechanical commutator (brushes), leading to the fact that they are maintenance free motors. Induction motors also have low weight and inertia, high efficiency and a high overload capability. Therefore, they are cheaper and more robust, and less prove to any failure at high speeds. Furthermore, the motor can work in explosive environments because no sparks are produced. Taking into account all the advantages outlined above, induction motors must be considered the perfect electrical to mechanical energy converter.
