🔍 Key Concepts

• Mechanical strength of motor components – which part is designed to carry weight and bending loads: the shaft, or the windings/core? • Protection of windings – what types of damage can occur if windings or laminations are used as bearing surfaces or lifting points? • Safe storage/rigging practices for heavy rotating machinery during maintenance

💭 Think About

• Look at each option and ask: which parts of the rotor are most vulnerable to mechanical damage (nicks, distortion, out-of-round) and should not be used to support or lift it? • Think about long-term storage: which method minimizes the risk of the rotor deforming, tipping over, or having its windings rubbed or crushed? • Consider standard shop practice: when a shafted component is removed (like a pump rotor or motor rotor), what surfaces are normally placed on blocks or slung with rigging?

✅ Before You Answer

• Verify which part of the rotor is structurally designed to carry its own weight during operation and handling (typically the shaft). • Check which options would put direct pressure or load on the windings and core, increasing risk of damage – these are likely poor practices. • Confirm that the chosen technique provides a stable, secure support that prevents tipping, bending of the shaft, or contact damage to the windings.
