Former-Wound Armature
- Definition:
- An armature where the conductors are thinner wires that are wound onto a form or former to create the armature winding.
- Characteristics:
- Thin Wire Conductors: The conductors are thin wires wound around a cylindrical or other shaped former.
- Flexibility: The thin wires allow for flexibility during winding and shaping.
- Insertion: After winding, the former-wound conductors are inserted into slots or set in place within the armature core.
- Connection: Connections between the wires are made to complete the armature winding circuit.
- Applications:
- Standard Motors: Commonly used in smaller to medium-sized electric motors and generators where space and weight considerations are important.
Comparison:
- Bar-Wound vs. Former-Wound:
- Conductor Size: Bar-wound armatures use larger sectioned conductors (bars) compared to the thin wires of former-wound armatures.
- Mechanical Strength: Bar-wound armatures offer greater mechanical strength and durability due to the larger and fixed conductors.
- Current Handling: Bar-wound armatures are preferred for applications requiring higher current handling capabilities.
- Complexity: Bar-wound armatures may be more complex to manufacture and assemble due to the larger conductor sizes and insulation requirements.
