    INTRODUCTION Electric motors are widely classified into two distinct categories: AC (Alternating Current) and DC (Direct Current). DC is distinguished from AC with its ability to flow in one direction. There are different kinds of DC motors but they all work on the same principle [1]. Electric motors are a means of converting energy. There is a wide range of DC applications ranging from small to big applications in the industry. It is of vital importance for engineers to know motors so that they

    Electric Motor An electric motor is a device that converts electrical energy into mechanical energy. In today’s life, electric motors have numerous applications including in homes, commercial buildings, and manufacturing industries. An electric motor works on the principle of Ampere’s law which states when a wire is carrying an electric current, it generates magnetic field around itself. In other words, an electric motor is able to generate motion by use of magnets and therefore its whole operation

    Electric Engines Introduction Electric Motor An Electric Motor Anything that turns electricity into motion, electrical energy into mechanical energy, is called anelectric motor. Working of Electric Motor Electric motors work on the principles of electromagnetism. When charges are still, they create electric fields. But when charges are in motion, they produce magnetic fields. Current in a wire, for example, produces its own magnetic field. This is what happens in an electric motor to create

    Illustrate the operating principles of a permanent magnet DC motor Introduction A DC motor is a simple electromagnetism that converts mechanical energy to produce electrical energy. It relies basely on the fact that like magnet poles repels and unlike magnetic poles attracts each other. A coil of wire with a current running through it, and induces magnetic field generates aligned with the center of the coil. Theory of a DC motor When the current flow through a circuit with electrons, it induces

    The power so delivered to the machine is distributed on three phases, while the maximum power level is imposed at the same time by the capacity of the distribution chain of energy and by that of the electric actuator. The three phase induction machines are considered as highly symmetrical electric systems, so any fault make it asymmetric. On the other hand, three kinds of asymmetry can characterize asymmetrical machines [Cop]: Electrical asymmetry results from unequal parameters of machine phases

    to have to find the difference between a certain amount of motors and also have to find out what made them so different between each other. We are trying to find out the physics of motors between a brushed and brushless motor. Motors How motors work motors convert electric energy to mechanical motion. For electrical motors, it can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force

    made for the selection of the motor is whether to use a dc brush or a brushless servo. The reasons for choosing brushless servo motor drives over the brush type dc motor drives are well known and include robustness, higher torque speed bandwidths lower maintenance The mechanical commutator and brushes of the dc motor also enforce severe limitations on its maximum speed and overcurrent capabilities. Assuming that it has been decided to use a brushless servo motor drive, the next decision to

  • Linear Induction Motor

    induction motors are electric induction motors that produce motion in a straight line rather than rotational motion. In a traditional electric motor, the rotor (rotating part) spins inside the stator (static part); in a linear induction motor, the stator is unwrapped and laid out flat and the "rotor" moves past it in a straight line. Linear induction motors often use superconducting magnets, which are cooled to low temperatures to reduce power consumption. In a traditional DC electric motor, a central

    Introduction Electric motor drive is an electromechanical contrivance that takes electrical energy from the supply and then transforms it into mechanical-energy by the avail of a motor to achieve a desired output. Most electric motors operate through the interaction of magnetic fields and current-carrying conductors to engender force. There are many types of DC motor drive and they differ from each other in terms of their utilization. Among the variants of DC motor drives, the Brushless DC motor drive and

    2.4 DC Motors Fig. 2.4.1 DC Motor DC motor is an electrical machine that converts the direct current electrical power into mechanical power. Most of the DC motors depends on the forces produced by magnetic fields. All types of DC motors have some internal mechanism, either electromechanical or electronics, to periodically change the direction of current flow in part of the motor. Most types produce rotary motion; a linear motor directly produces force and motion in a straight line

    Introduction The 3-phase induction motor is the motor used most frequently for industrial drives because of its excellent reliability, its simple and thus low-cost construction and its low maintenance costs. The 3-phase induction motor is an (AC Electric motor) by which the stator is connected to 3-phase balanced supply creates magnetic field that rotates in the same time with AC oscillation. Then the synchronous rotor produces magnetic field at the same speed of stator field then an induction

    INTRODUCTION An electric motor is an electromechanical device that converts electrical energy to mechanical energy. This mechanical energy is used for rotating a pump impeller, fan or blower, driving a compressor, lifting materials etc. DC motors are especially used in applications that require high starting torque or smooth acceleration over a wide speed range. A dc servo motor which is usually a dc motor of low power rating is used as an actuator to drive a load. A dc servo motor has a high ratio

    Introduction The three-phase induction machine is the most widely used rotating machines. An induction machine offers an almost constant speed within its normal operating range when operated off a constant-voltage, constant-frequency, and electric power source. Economically, the cost of purchasing these machines can be considered very low, and they require little maintenance. However, controlling the speed of this type of machine is difficult and can be considered very expensive. In this paper,

    An induction motor has two main parts; a stator and a rotor. The stator is the stationary part and the rotor is the rotating part of the induction motor. Rotor is connected to the mechanical load through the shaft and it sits inside the stator. It rotates due to torque produced by electric current; obtained by electromagnetic induction from the magnetic field of stator winding. Thus an induction motor has no electrical connection with the rotor. Early development Galileo Ferraris described an induction
