COURSE TITLE: AC Generators and Motors
COURSE NO: E03-008
COURSE PROVIDER: A. Bhatia
AC Generators and Motors
Course Highlights

This online engineering PDH course provides a basic understanding of AC generators and motors, explaining how to use them, how to calculate power, and determine torque considerations.

 

An alternating current generator, or AC generator, produces an alternating current, which means the voltage produced alternately reverses from positive to negative polarity, producing a corresponding change in the direction of current flow. Much like a DC generator, an AC generator requires a coil to cut across the force lines of a magnetic field. This coil is attached to two slip rings, which deliver the current to and from the load destination, thus completing the circuit. Alternating current generators are often called "Alternators".

 

An alternating current motor, or AC motor, uses electrical 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 motor starting include reactive (capacitor start and inductive start), and electronic (frequency drives and soft start drives). The reactive start method is usually used on fractional horsepower motors, and the electronic method is usually reserved for larger motors.

 

This 3 PDH online course is applicable to students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers who are interested in gaining a better understanding in AC generators and motors.

COURSE TITLE: Twenty Ways to Optimize Energy Efficiency in the Use of Induction Motors
COURSE NO: M06-021
COURSE PROVIDER: A. Bhatia
Twenty Ways to Optimize Energy Efficiency in the Use of Induction Motors
Course Highlights

This online engineering PDH course provides 20 different strategies to guide you into the electric motor evaluation process and highlights common ways you can improve system efficiency and reliability to achieve permanent long-term electric cost reduction.

 

The majority of electrical energy consumed in most industrial facilities is used to run electric motors. Annual energy operating costs of electric motors usually far exceed purchase prices. For example, a typical 25 horsepower (hp) motor running at full load for 6,000 hours per year would consume nearly $10,000 of electricity annually. An average purchase price for a motor of this size would be only $500 to $600.

 

Opportunities for energy conservation are wide spread and applicable to new as well as old plants. It is important to note that majority of savings will accrue not on the motor itself but on the motor-driven system as a whole. Energy efficiency decisions are important decisions that affect operating cost for the life of the equipment. By optimizing the efficiency of your motor-driven systems, you can increase productivity while achieving substantial energy and dollar savings.

 

This 6 PDH online course is intended for electrical & control engineers, energy auditors, operational & maintenance engineers, contractors and system designers who are responsible for design and operation of the system.

COURSE TITLE: Understanding Motor Nameplate Information: NEMA vs. IEC Standards
COURSE NO: E03-009
COURSE PROVIDER: A. Bhatia
Understanding Motor Nameplate Information: NEMA vs. IEC Standards
Course Highlights

This online engineering PDH course provides a brief overview of how to read and interpret motor nameplate information, as well as highlights the major differences between NEMA and IEC motor standards.

 

One of the most important aspects of making motors interchangeable is ensuring that nameplate information is common among manufacturers. International standards such as National Electric Manufacturers Association (NEMA) and International Electrotechnical Commission (IEC) provide key electrical, mechanical, construction and reliability parameters on the motor largely to benefit consumer to expect "standard" motors from different manufacturers that meet or exceed the minimum performance parameters, and for the most part, be about the same size.

 

This 3 PDH online course is intended for mechanical and electrical engineers, energy auditors, service technicians, operational and maintenance personnel who are involved in designing, specifying, maintaining or replacing motors.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Who determines the nameplate information
  • What does rated volts, FLA, Hz, PF, Torque or HP means
  • What does time rating or duty cycle means
  • What does rating temperature or the insulating rating means
  • What does frame size and enclosure means
  • What does service factor means
  • What do motor design codes mean
  • What does full load RPM and Synchronous speed means
  • How does IEC terminology differ from NEMA standards
