Actuator – Troubleshooting and repair
An actuator is a component of a machine that is responsible for the movement and control of a mechanism or system, for example by opening a valve. Simply put, it’s an “engine.”
An actuator requires a control signal and a power source. The control signal is relatively energy efficient and can be electrical voltage or current, pneumatic or hydraulic pressure, or even human force. Its main source of energy may be electric current, hydraulic pressure or pneumatic pressure. When receiving a control signal, an actuator responds by converting energy from the source into mechanical motion. In the electrical, hydraulic and pneumatic sense, it is a form of automation or automatic control.
An actuator is a mechanism by which a control system acts to carry out an operation or task. The control system may be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), human, or other input.

Presenting research findings from the author's own experience and important contributions from others, Mechanical Design of Electric Motors highlights innovative and advanced electric motors developed over the past several decades.
Mechanical Design of Electric Motors
The importance of electric motors is well known in different fields of engineering. The book provides comprehensive coverage of different types of electric motors, including DC motors, three-phase and single-phase induction motors, synchronous motors, universal motor, AC servo motor, linear induction motor, and stepper motors. The book covers all the details of DC motors, including the torque equation, e.m.f. reverse, characteristics, types of starters, speed control methods and applications.
The book also covers the various methods of testing DC motors, such as the Swinburne test, braking test, slow-down test, field test and Hopkinson test. The book further explains three-phase induction motors in detail. It includes production of rotating magnetic field, construction, operation, effect of slip, torque equation, torque ratios, torque-slip characteristics, losses, power flow, equivalent circuit, effect of harmonics on performance, pie chart and applications. This chapter also includes the discussion of induction generator. The book teaches the various starting methods and speed control methods of three-phase induction motors. The book incorporates the explanation of different single-phase induction motors. Synchronous motor chapter provides the detailed discussion of construction, working principle, on-load behavior, phasor diagram analysis, Vee and Inverted Vee curves, trawling, synchronous capacitor and applications. The book also teaches the different special machines such as single phase collector motors, universal motor, AC servo motor, linear induction motor and stepper motors. The book uses simple, clear language to explain each topic. The book provides the logical method of explaining different complicated topics and step by step methods to make understanding easier. Each chapter is well supported by necessary illustrations, self-explanatory diagrams and a variety of solved problems. The book explains the philosophy of the subject which makes the understanding of the concepts very clear and makes the subject more interesting.
