Commutator slip ring handbook

I claim to have invented: 1. The combination of a d.c. machine and apparatus responsive to the magnetic fields in the machine, comprising: said d.c. machine having (a) casing, (b) a rotatable element located in said casing and having an axis of rotation, the rotatable element including a commutator and an armature, (c) means in said casing for applying a magnetic field to said armature and (d Electrical Generator or Motor Structure, for a brush, commutator, slip ring, or other collector for a dynamo electric machine. 314 , Electric Lamp and Discharge Devices: Consumable Electrodes, subclass 129 for a consumable electrode device (e.g., an arc lamp) provided with means to transfer electric current from a lead wire to a moving electrode. Gary Braun Brehob Corp. Indianapolis, Indiana Technical Education Committee Member When servicing DC motors, one of the many tests we do to determine the condition of the commutator is to check it for loose bars. We check for loose bars by lightly tapping the face of the commutator with a very small hammer. Then we check for suspicious sounds and move­ment or vibration of the bars as they NAVSEA Handbook S9310-AC-HBK-010 (Commutator/slip ring Maintenance Handbook) What is an indication of an open or loose connection in the armature? A bright spark which appears to pass completely around the commutator What is indicated by a bright spark each time the contact passes under a brush? Retaining rings Coil slot Balance plug Collector rings Collector fans There are, of course, variations on this configu-ration. For example, while the illustrated design uses radial fans, other designs use axial fans. GE Generator Rotor Design, Operational Issues, and Refurbishment Options GE Power Systems GER-4212 (08/01) 1 Mechanical A slip ring or commutator is attached to the rotating shaft. A spring is used to push the brush into the slip ring or commutator to maintain contact. The surface of the slip ring or commutator should not be too smooth/glossy or too rough in order to ensure good brush contact and performance. Electrical Inspect slip rings and commutators for damage and for wear limits, using 2.2 for criteria. Record data. 3.24 Inspect brush rigging for cracks, chips, worn areas, distortion, spring condition, and insulating material for cracks and arc paths. Record data. 3.25 Inspect leads and terminal lugs for damage and defects. Machinery Handbook; H-28 Federal Standards for Thread; Equipment Demonstrate safe operation and upkeep of shop equipment. The Equipment list is representative of tools Cutting Machine, Commutator/Slip-Ring, Portable; Drill Press w/Tilting Table; Disintegrator, Metal, Portable; Electroplating Machine; Grinding Machine; For long-term storage, lift the brushes away from the commutator/slip rings to prevent a chemical reaction (sometimes called "photographing") that can discolour the underlying commutator or slip ring. When practical, store the springs in the relaxed state to prevent a gradual loss of spring pressure. Follow best practices… even for "small" motors Edition. LEETCODE 50 COMMON INTERVIEW QUESTIONS.
