Fixing and Replacing Electric Motor
During the summer season your electric fan is one of the most important things that you would need but your summer fan doesn’t work and after couple of times trying to open it again the fan goes weak and it doesn’t blow much air and you are wondering if what are you going to do with it. The problem is that you don’t have enough money to purchase a new one and you really don’t want to throw it away. You’ve find out that the problem is the motor itself and that’s the main reason why it doesn’t work. <br />Then while browsing a youtube Video you saw a video tutorial on how to fix a motor spending only less than £ 3 there are youtube videos available for you to use but you want a manual on working with. But before doing it so, I would remind you that be sure to remove the plug first before working on anything and make sure that you are always safe.<br /> According to Ehow.com these are the steps on how to fix and replace broken motor parts.<br />Unplug your motor and discharge the capacitor before you begin work. Make a discharge tool by clipping your jumper to the leads of a resister, and clip the free probe of your jumper to a blade on a screwdriver. Lubricate all the moving parts with an SAE 20-weight motor oil. If your motor has oil cups, fill them to the top.<br /><br />Check your bar-to-bar commutator. Set your volt-ohm meter on RX1, and touch the probes to the adjacent bars all around the commutator on the end of your motor. All your readings should be about the same. If you have an unusually high ohms reading, you likely have an open circuit. If you get a zero reading, there's a short in that bar.<br /><br />Probe the field coils on your motor. Set your volt-ohm meter to RX1 and clip the probes to the field coil leads. High ohms or infinity indicates an open circuit. The motor in multispeed appliances will have several field coil leads. Look for damage or wear on the housing brushes. Remove the brushes from the housing and check them out. Replace the brushes when they're shorter than they are wide.<br /><br />Check your brushes to make sure they are fitting properly. Your brushes should move freely in their housings. Replace any springs that appear to be weak. Clean the housing and the brushes with contact cleaner. Polish your commutator if it appears rough. Hold fine sandpaper around your commutator and turn it. Then burnish the bars with hardwood stick.
