Electric Motors in HVAC
A "Rock~Solid" 4 Hour Fundamentals Course

Electric motors are used in just about every piece of HVAC equipment manufactured today. They are used to supply combustion air, deliver fuel under pressure, move air through duct systems, pump refrigerant vapor in AC and heat pumps, move water through baseboard and radiant heating systems, extract flue gasses from furnaces and boilers, and the list goes on and on. We are also seeing a new very efficient breed of motor out there, referred to as EMC motors. EMC motors will be used in a wider variety of applications as time goes on.

Since we are speaking of motors, do you know the following terms: PSC, CSCR, CSIR, FLA, RLA, LRA, SHADED POLE, ECM, INDUCTION RUN, SINGLE PHASE, THREE PHASE, TWO POLE, FOUR POLE, EIGHT POLE, POWER FACTOR, SYNCHRONOUS SPEED, INDUCTION SLIPPAGE?

How about starting various types of motors, do you understand the theory behind potential and current relays, start and run capacitors, centrifugal switches, solid state starters, and why potential relays are not used unless a capacitor is also included in the circuit? Do you know how to reverse a three phase motor, and how to hook up a motor starter with heaters?

Our "Electric Motors in HVAC" class will cover these important topics and a lot more. You will finally understand why motors work, what regulates their RPM, and what the term horsepower really means. We will also cover why multi-speed blower motors are really single speed motor, and why the motors assumes different speeds, or RPM's, based on the wiring and the load.

If you don't have a solid understanding of this subject mater, you need to attend our "Electric Motors in HVAC" course. This is a "solid base" course, which means you will be hammered with important technical information time and time again until you know the information cold. After taking this course, you will have the ability to effectively identify, troubleshoot, and correct motor problems.
