You will be redirected once the validation is complete. Troubleshooting Motor Controls 3.0.1 is a very flexible and effective tool in which you learn how to troubleshoot motor control circuit faults. Carry out continuity test using a Multimeter across each fuse. Introduction to Motor Controls. Monroeville, PA 15146, P Interpretation of Circuit symbols, troubleshooting procedures, Digital and Analog Multimeters, the clamp on ammeter and insulation tester. There are also other factors which greatly affect the performance of electric motors such as low resistance, dirt, moisture, over-current and vibrations. 1. In the direction of the motor, if you catch a phase-on-phase short, then the motor would require the winding to be replaced. First, engage the starter with manual rotation and measure the resistance across it. The resistance measured would represent the horsepower, e.g. causing fluctuating or low operating voltages in the control circuitry and motors. is the best way you can analyze and subsequently troubleshoot a failed system. Mcc.exe, tmc.exe or TMCDemo.exe are the common file names to indicate this program's installer. Please enable JavaScript on your browser and try again. This troubleshooting guide can also be applied to other types of three phase induction motors: This troubleshooting guide is by no means exhaustive but can provide guidance for the resolution of commonly encountered problems as far as poly-phase induction motors are concerned. Fax: 412.373.2900 If you find a blown fuse, remember that it would only indicate a faulty line, and replacing it won’t be a solution. On the other hand, in the direction of the supply, use the megohmmeter to conduct an insulation resistance test. A step-by-step approach is the best way you can analyze and subsequently troubleshoot a failed system. Phone: 412.373.3700 Once the problems have been identified and the motor repaired, re-install the motor and the motor control. When the garage door doesn't budge … Model. Then, disengage the starter and carry out a ground test using the megaohmmeter. Capacitance is measured in microfarads. The general rule for AC devices is normal operation under 2 megaohms when tested across ground, while DC drives operate not less than 1 megaohm. Run it, and record voltage, current and other measurements to make sure they match the nameplate specifications. First step in the Simutech Training System. burnt windings, broken rotor, etc. Take input voltage to the motor using the volt ohmmeter. The widespread use of motors in fields ranging from manufacturing to household applications means that downtime due to a malfunctioned motor can result in a great loss of productivity. An outboard motor shifter and throttle control is the unit that controls the amount of throttle or speed of the outboard motor. Part Picture. Please enable cookies on your browser and try again. If during the testing you observe low ground readings, then test the stator winding phase resistance, which would give you an accurate idea of the location of the fault. Step 4: Plug the motor into a different outlet. Here, you will troubleshoot a motor control circuit consisting of a reversing motor controlled garage door. If the motor does not respond, continue to the next step. hbspt.cta._relativeUrls=true;hbspt.cta.load(548870, 'e95e8e3e-dd0b-47f6-959d-3345ce6f155f', {}); Premier Automation Most of the electric motor failures occur at the start up.
