2 Permanent M Up to speed in any variable speed application. Whatever your needs in variable speed applications, you can trust our 200/00/00/00 series PMDC motors. Designed and built under the highest quality process for General industrial needs, our products are there to provide reliable performance for a long time. Our motors will provide constant torque over the entire speed range when properly match to the speed Controller. When properly matched with the Controllers, our motors can achieved stable / Torque regulation at near zero rpm to full speed of the motor. In addition, We can customize our mechanical or electrical parpmeters to suit your needs. For precision applications, we provide special encoder mounted on the motor shaft to achieve precise speed regulation and high torque at low speed without lengthening the motor. 00 / HP W 000 /2 HP 0 W 00 /0 HP W 00 / HP W 020 / HP 20 W 00 / HP 0 W 0 / HP W 020 / HP 20 W

22 COMMUTATOR After several hours of operation, the commutator surface under the brush should take on a darker bronze color. This is due to selfgenerated film caused by normal commutation. This coloration should be even, without blotches or black areas. A shiny copper color or black streaks in the brush tracks are signs of improper commutation or contamination by a foreign material. Contact us for assistance in correcting these problems. If the commutator becomes rough and burned, or becomes black, it should be cleaned of dirt and carbon particles. This can be done by wiping it with a dry, lint-free cloth. Also vacuuming or blowing out the motor with a dry air supply are suitable cleaning methods. Do not use solvents or cleaning soultions on the commutator. To remove spots or contamination that will not wipe off, wrap a strip of coarse (0# grit) sandpaper around the commutator. Then rotate the armature back and forth by hand. Do not use emery cloth as this contains electrically conductive materials. Another method of commutator resurfacing is to use a commercially available commutator dressing stone. This should only be done by trained and experienced people. This stone should be taped or attached to the end of a stick made of electrically nsulated material. The motor should be run at about half speed and the stone applied lightly to the commutator surface. This operation must be done with no load on the motor. Be careful of applied voltage hazards. Temperature Degree F. HUMIDITY AND BRUSH WEAR ZONE OF SAFE BRUSH OPERATION Danger Zone Too Low Humidity Percent Relative Humidity This curve represents 2 grains of water per cubic foot of dry or. grams of per cube meter of dry air Temperature Degree C. TURNING THE COMMUTATOR After commutator turning, check its run-out with the bearings on V block. For all commutators,maximum run-out is.002".new and minmum commutator diameters are in the cart that follows. FRAME COMMUTOR BRUSH TRACK DIAMETERS NEW MOTOR COMMUTATOR DIAMETER INCHES MINIMUM DIAMETER AFTER REFINISHING INCHES NOTE: The above diameters are approximate. They are for standard design and speed motors. High speed motors require larger minimum bar diameters. The surface of the commutator should be smooth and round. This can be shecked while the motor is running at low speed. Press lightly on one brush with an insulated stick. Do not use a lead pencil as this contains electrically conductive graphite. If you feel movement of the brush, it suggests a worn or uneven commutator. The armature must be removed from the motor and the commutator turned by a qualified repair shop. RAPID COMMUTATOR WEAR Light electrical loads and contamination are the usual causes of rapid commutator wear. Light loading may require the removal of some brushes on motors with multiple brushes per pole. Sometimes we substitute a low surrent density brush grade. There are also brushes available that have a mild polishing action. Thess prevent certain chemicals, especially chlorine and silicone, from attacking the commutator. Brushes are available for plastic extruder applications where PVC is present. Usually, you do not have to change the design or grade of the brushed on new motors unless special operating conditions exist. DO NOT CHANGE BRUSH GRADES OR THE NUMBER OF BRUSHES PER POLE. DOING SO MAY VOID THE WARRANTY AND MAKE THE MOTOR UNSAFE. CONTACT YOUR LOCAL AGENT DISTRICT OFFICE OR AN AUTHORIZED SERVICE CENTER FOR TECHNICAL ASSISTANCE. COMMUTATOR UNDERCUTTING Check the commutator mica between bars for an under-cut depth of /" minimum, /' maximum. The grooves of the under-cut are to be free of mica and chips. CAUTION:Be very careful when repainting a drip proof motor. Do not get any paint on the commutator. Paint on the commutator will show up as black marks in the brush tracks. Also, excessive brush sparking or erratic operation can be caused by paint or other material on the commutator.

23 GOOD CONDITION GOOD CONDITION SATISFACTORY CONDITION LIGHT FILM Uniform coloring indicates satisfactory operation of machine and brushes. Film color is largely an effect of thickness,therefore provided the film is uniform, it is perfectly acceptable. DARK FILM A further example of a commutator in excellent condition. Film is much darker than illustrantion : however, uniformity is the feature to consider rather than color. LIGHT AND DARK BAR PATTERN This is not a bad condition, but in our experience,it is known that machines having this commutator pattern have operated with satisfactory results for long periods of time. Alternative bars or every rd, th, etc. This is related to the winding design of the armature. Difficulty caused from split windings crossing in the same slot. UNSATISFACTORY CONDITION STREAK FILM WITH NO COMMUTATOR WEAR Frequently due to underloaded operation, machine grossly overbrushed or brush grade incorrect for particular machine application. Atmosphere and environmental conditions can contribute. UNSATISFACTORY CONDITION UNEVEN FILM Patchy colors of varying densities and shape. Due to unclean operating conditions or incorrect physical condition of commutator. UNSATISFACTORY CONDITION FILM WITH DARK AREAS These areas can be isolated or regular Commutator out of round. Can be caused by vibration or mechanical deficiens in equipment operation, bearing, coplings, etc. UNSATISFATORY CONDITION EXAMPLE OF POOR COMMUTATOR MACHINING Bars are low on entry and leaving edges, giving riding on the middle of the bars. UNSATISFATORY CONDITION EXAMPLE OF POOR COMMUTATOR MACHINING Bars are low in the middle, giving rise to the brushes riding on entry and leaving bar edges. This and the previous illustration indicate the need for better maintenance. UNSATISFATORY CONDITION STREAKY FILM WITH COMMUTATOR WEAR This is a further development of example. Brush grade, machine applications and working environment all suspect. Earlier corrective action should have been taken. UNSATISFACTORY CONDITION DOUBLE POLE PITCH. Darkening of commutator in sequences two pole pitches apart is due to armature fault, defective coil, riser bars or equalizer connections. UNSATISFACTORY CONDITION BRUSH CONTACT MARK Storage of machines for lengthy periods, with brushes in position. Can also result from operation of machine in prolonged stall conditions. UNSATISFACTORY CONDITION BAR EDGE BURING CAUSE HIGH MICA illustration shows high mica in every slot. Same effect can occur on one bar only. Similar conditions can be caused by a high or low bar. UNSATISFACTORY CONDITION SMALL BRIGHT SPOTS Related to overloaded machines and low brush pressure. Due to sparking under brush which gives rise to spots being of a random distribution. If not corrected will result in scored commutator. GUIDE TO COMMUTATOR APPEARANCE 22
