Which of the following statements represents the FIRST step in seating new brushes on slip rings?

🔍 Key Concepts

• Purpose of seating brushes on slip rings (what are you trying to achieve mechanically and electrically?) • How seating compound and sandpaper are used differently during maintenance • Why you must avoid damaging or grooving the slip ring surface during the initial step

💭 Think About

• Which option sounds like a gentle, controlled way to begin shaping the brush face to the curve of the slip ring, rather than an aggressive action or a long-duration procedure? • Look at the answers that involve running the machine for hours – are those more likely to be initial steps or later steps after the brushes are roughly fitted? • Which actions are likely to be used only after the brush already has fairly good contact with the slip ring surface?

✅ Before You Answer

• Identify which choices involve running at no load for hours – these are usually not the very first step, but part of final seating/finishing. • Decide which method could scratch, groove, or contaminate the slip ring if done incorrectly, and whether that is appropriate as a first step. • Think about which method is typically used to get the initial contact area between brush and ring to match before any extended running time.
