Miscellaneous drives: deep vacuum pumps, recovery machines, ice makers, EEV stepper motors, among others.īefore the advent of electronically controlled motors, there were two general classes used to identify electric motors: single phase induction motors and three phase induction motors. Pump drives: condensate pumps, hydronic system pumps, chilled water pumps, geothermal system pumps, and cooling towers. HVAC runs on electric motors, which are used in several general classifications:Ĭompressor drives: hermetic direct drive and external driveįan drives: condensers, evaporators, induced draft, air circulation Indeed, today’s global market for electric motors is close to 100 billion US dollars and is expected to grow to 141 billion by 2022 according to Sherry James of Grand View Research. Years later in 1883, Nicola Tesla invented the first induction motor with rotating magnetic fields thus starting a second industrial revolution still evident today. Faraday had converted chemical energy from a battery into mechanical motion creating the threshold to our world in motion. The great British scientist, Michael Faraday, experimented with electricity and magnetism and, in 1821, he set in motion a copper conductor rotating around a magnet sitting in a bath of mercury. By the time the refrigerator, vacuum cleaner, washer/drier, range hood, outdoor unit, submersible pump, and several other devices are counted, I am employing north of 25 motors nearly every day. Even at home, the ubiquitous electric motor is indispensable.Īs I sat down to write this article, I performed a quick mental survey of the electric motors just in my basement: furnace (three motors, including condensate pump) HRV (three motors) upright freezer (one motor) sump pump ( one motor) propane stove (one motor) desktop computer (one motor) printer (one motor). Whether designing new products, specifying equipment, installing, maintaining or repairing a variety of heating, ventilation or cooling products, an electric motor and its needs are regularly the centre of attention. Everyone involved in HVAC and refrigeration works with electric motors almost every day. These fellows that repair these motors would know the reversing proceedure on all these motor of G/E. Bring the motor to a motor repair shop and have them look at the winding and reverse it by knowing how it's wired up. I just thought about one here if all else fails. You can read them sometime by doing this where you can't read it normally. Then reverse the picture to make it look like a blue print in black. If you have a flate bed scanner you can put the motor tag if removiable on the scanner and scan it. Tring to blind reverse it is very hard for they have about 10 different ways to reverse different type motors the G/E has. Try to find the manufactor of the air compressor on the internet or by toll free call look up of the manufactor and try to get them to send you a diagram of wiring or look it up on the internet for a operator manual that away. Without the Operator manual or the name plate with wiring diagram on motor your shot. I looked on ge.com but they dont seem to have diagrams, at least not that I can find using their search feature. GE Tri Clad Capacitor motor Model# 5KC184AG201C I dont have a clue how to switch it without the diagram.ĭoes anyone know of a website, or place to call or mail to find out the wiring connections? However, I am barely able to see 1/10th of it. There is a paper label on the access cover, which (used to) have the diagram. I already installed the receptacle for it, but then discovered this problem. I want to switch it over to 240V, which requires 9.5Amps according to the label. So, it trips the breaker if the tank is partially full, or the weather is cool, and the oil thick. The problem is that this motor was wired for 120V. The motor is designed to run on either 120V or 240V AC. I bought an old air compressor that has a 1.5HP electric motor made by GE.
