  The motor book (on photo: Single phase magnetic Induction motor with exposed rotor and coil) After all, motors are always designed to carry out specific tasks. As this is a Grundfos publication, it is only natural that we should pay special attention to motors used for pumps – although much of the information contained within these pages. The content of this book is divided into three basic parts: 1) control-oriented description of induction motors, 2) control methods, and systems, 3) control means. An induction motor is presented as an electromechanical power converter, and basic relations between the electrical, magnetic and mechanical quantities in the motor will be explained.   AC motors play a major role in modern industrial applications. Squirrel-cage induction motors (SCIMs) are probably the most frequently used when compared to other AC motors because of their low cost, ruggedness, and low maintenance. The material presented in this book is organized into four sections, covering the applications and structural properties of induction motors (IMs), fault Cited by: 2. It has been more than a century since the principle of the operation of induction motors was discovered. The first industrial motors of this type were constructed at the end of the Nineteenth Century and soon gained the favor of users who appreciated their raggedness, simplicity and relatively low manufacturing cost compared to DC commutator s: 1.

  What is an Induction Motor? An induction motor (also known as an asynchronous motor) is a commonly used AC electric an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. The rotor of an induction motor can be a squirrel cage rotor or wound type rotor. The induction motor especially three phase induction motors are widely used AC motor to produce mechanical power in industrial applications. Almost 80% of the motor is a three-phase induction motor among all motors used in industries. Therefore, the induction motor is the most important motor among all other types of motor. An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. An electrical motor is a device that has brought about one of the biggest advancements in the fields of engineering and technology ever since the invention. principle-of-three-phase-induction-motor/ Per-phase equivalent circuit • Motor Slip • R 1 and R 2: stator and rotor winding resistances • X 1 and X 2: stator and rotor winding leakage reactances • X m: magnetizing reactance • R c: core loss resistance.

The induction motor drives can provide high productivity with energy efficiency in different industrial applications and are the basis for modern automation. This book provides an account of this developing subject through such topics as modelling, noise, control techniques used for high-performance applications and by: 7. An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An induction motor's rotor can be either wound type or squirrel-cage type. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo drives, providing readers with the knowledge to select the right technology for a given job. Austin Hughes' approach, using a minimum of maths, has established Electric Motors and Drives as a leading Reviews: 2. Induction motor: voltage applied to the stator windings produce an induced voltage in the rotor windings The difference is that, in the case of the induction motor, the secondary windings can move Due to the rotation of the rotor (the secondary winding of the IM), the induced voltage in it does not have the same.
