Choosing the best remediation method depends on a thorough understanding of the potential current paths in an installation . Electric circuits – problems and solutions. On belt-driven applications, poor alignment increases axial bearing load. To ensure that heated air is not recirculated to the motor’s air inlet, it may be necessary to supply a sufficient volume of filtered air from an external source. If your electrc motor is an "open" design you can see into the motor housing; look for clots of dust and oil that may be blocking the cooling fan and causing the motor to overheat; overheating can cause the motor's thermal overload switch to shut the motor off (and … Misalignment of the motor and driven load also contributes to premature bearing failures, as does vibration. It is mandatory to procure user consent prior to running these cookies on your website. Rich Schiferl and Michael Melfi. The working principle of this motor is to create rotational motion with the help of electromagnetism. For critical applications, it also pays to install overload protection that is sized correctly for the motor rating. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. Fig. Motor misaligned to load. With sleeve-bearing applications, it is also important to mount the motor level to ensure proper lubrication and accurate level checks. You also have the option to opt-out of these cookies. Our solutions will save you time and money through innovated electric motor products we can source through our factory partners in Asia. Surges are common and last for a microsecond but if you experience frequent surges lead to equipment damage that degrade life expectancy particularly. What is the full-load speed? Regular servicing helps in minimizing the problems. Mechanical overload is the leading cause of failure for stator windings. If the bearings are bad, you will hear noises or feel roughness. It can damage the motor by blocking the cooling fan which causes its temperature to raise. We also use third-party cookies that help us analyze and understand how you use this website. Metallurgical ContentMotor SwitchesAir MotorsFractional HP and General Purpose MotorsSynchronous Motors Motor Switches Motor starting switches have been developed for a wide variation of load requirements, and special switches are available for operation in damp or dust laden atmospheres with high efficiency. If you want to make a plant manager’s day, just say: “Production’s down because a motor failed.” Fortunately, such situations can usually be overcome with some relatively simple techniques and straightforward solutions to protect the bearings and stator windings. 1. It is used in a large number of applications, either for home appliances or large commercial units. Other contributing causes include ­­contaminated lubricants, using the wrong lubricant or viscosity for the application and mixing incompatible greases or oils. For relieving this problem, check for the damaged bearings, loose … By Thomas H. Bishop, P.E., Electrical Apparatus Services Association (EASA). Would you like to write for us? At no-load and rated voltage, the speed is 1200 rpm and the armature current is 3 A. Our site includes quite a bit of content, so if you're having an issue finding what you're looking for, go on ahead and use that search feature there! You would probably say that it works on electricity. Test the continuity and resistance of new and rewound electric motors. Similarly, the only true solution for repetitive transients from VFDs would be a VFD output without transient voltages. DC Motors Solution Problem (1): A 20hp, 250V shunt motor with R a=0.22 Ω, R f=170 Ω. Defective motor bearings. Driver Side Windows are checked during the MOT or NCT (National Car Test). Calculate the generated e.m.f? These two vulnerable components are root causes of the vast majority of motor failures. For fixing this problem, check the fan blades for any dust and dirt accumulation. Excess heat is always the enemy when it comes to stator windings, because it can prematurely age the insulation system. Identify problems from the list below, as well as the most appropriate solution. This problem may be caused due to a tripped fuse and/or failure of the power supply. contents chapter previous next prep find. You can rest assured that you will not be disappointed. Here again, the solution is straightforward: Bring the voltages at the motor to within tolerance. Since most motor failures can be traced to damaged bearings or stator windings, it makes sense to leverage techniques and solutions to protect these components. Learning these problems and solutions will save you … Actually, service factor capability is intended only for short-term, intermittent use. It is also important to use inverter-duty supply cables and to keep the cable length within the motor manufacturer’s guidelines. Although “prevention” would be the ideal solution for single-event transients, the practical remedy is to install transient-voltage protection in the motor terminal box. Electrical overload or over-current is caused by an excessive current flow within the motor windings, exceeding the design current which the motor is able to carry efficiently and safely. contents: electrical machines chapter 01: electromagnetism. Prior to starting with the repairs, make sure to turn off the main power supply in order to prevent an electrical shock. It may also result in over-tensioning of belts, which places excessive radial loading on the drive-end bearing. The rotating blades mash and mix things for you. Wanted : Electric current (I) Solution : Equivalent resistor (R) : R 2 and R 3 are connected in parallel. Known : Resistor 1 (R 1) = 6 Ω. Resistor 2 (R 2) = 2 Ω. Resistor 3 (R 3) = 2 Ω .
