Selecting an Energy-Efficient Motor ...lectrical energy consumed in the U.S. is used by electric motors. Energy savings amounting to many times the initial cost of a motor can be realized by selecting an energy-efficient motor for a new application. Substantial savings can also be realized by replacing older, inefficient motors with new energy-efficient models. However, selection of an energy-efficient motor is not always cost  more...

Overcurrent Protection ...the amperage rating of the conductors (cable), equipment (motors, instruments) or other devices in a circuit. Without adequate protection, an overcurrent can damage conductors and equipment and potentially harm people. Protection devices, such as fuses and circuit breakers, are installed in a circuit to detect an overcurrent condition and selectively protect equipment and personnel, while  more...

Induction and Synchronous Motor Fundamentals ...o most common motor classes are synchronous and induction motors. Synchronous motors are more efficient than induction motors, but are more expensive and complicated and typically have a shorter life span. This course covers fundamentals of these motor classes and is geared towards engineers of all disciplines who are responsible for sizing, specifying, selecting, or purchasing electric motors.  more...

Industrial Motor Control ...The intention of this course is to show how many types of motors are turned on and off. A number of different AC motors are looked at, and ways to start and stop them are addressed. Reversing techniques are also addressed. Then various Electronic techniques for controlling motors are addressed. Both Alternating Current motors and Direct Current motors are covered. All in all, this is a very  more...

Written Pole Motors Overview This is a three-hour course about a relatively new form of single-phase induction motor known as the Written-Pole? Motor. The motor was developed by Precise Power Corporation and it uses an innovative approach of controlling the magnetic field of the motor to reduce the starting current requirements. The result is a motor that has starting current requirements of only about twice the  more...

Alternating Current Motors and Generators ...rical energy to produce motion and torque. Very simple AC motors are called "Squirrel cage motors"; these have only one or more stationary coils within which a special kind of mechanical rotor is free to rotate. There is no electrical connection to the rotor from the outside. Most AC motors require a starter, or method of limiting the inrush current to a reasonable level. Types of  more...

Direct Current Motors and Generators ...re revolves. Adjustable speed is difficult to obtain with motors whose armatures are connected to fixed frequency power lines (AC motors). Here is where DC motors shine; their rotating field speed depends on the rotor speed itself. The speed of DC series motors varies with load, and torque varies inversely with speed. This makes them particularly suitable to starting high inertia loads such as  more...

Mechanical Design of Pumping Stations - Pump Drivers ...g pumping station drivers, including engines and electric motors. This course is particularly relevant to engineers responsible for designing flood control pumping stations. However, it is also relevant to any engineer responsible for or interested in learning about selecting driver equipment for large pumping applications. The student must take a multiple-choice quiz consisting of ten  more...

Pumps ...he course also discusses pump drivers, including electric motors, turbines, diesel engines and air-operated pumps. Prevention of motor overload and applications for variable speed motors are discussed. Finally, piping suction and discharge piping problems are discussed. Methods are discussed to reduce the potential for entry of vapor into the pump suction. Parallel and series pump  more...
