Overmolded Wound Stators

Reduces vibration, thermal rise, and costs; integrate components; offers reliable performance.

Overmolded Wound Stator

  • Magnet Wire AWG 24 to AWG 32
  • Multiple lamination stack heights molded in same injection molding tool
    • 13mm, 16mm, 18mm, 33mm, 66mm
  • Various Features Molded In
    • Ball Bearing
    • Flange with threaded brass inserts
    • Bayonet lock
  • Reduced stack up tolerances compared to prior steel and aluminum assembly
  • Reduced vibration
  • Decreased thermal rise
  • Component integration

Overmolded Hybrid Electric Stator

  • Resin transfers heat from stator end turns to cooling jacket
  • Thermally conductive, electrically insulative encapsulant
  • Shut off on large lug termination
  • 125 lb stator overmolded

Overmolded Wound Stator

  • Molded in ball bearing
  • Molded in threaded inserts
  • Component reduction
    • Eliminate steel shell, aluminum end bell, bearing retainer, lead wire grommet
  • Tolerance stack up reduction
  • Reduced thermal rise and hot spot temperatures
  • Environmental protection for exposed outside use

Overmolded Wound Stator

  • Shutoff on flex circuit
  • Overmolded PCB
  • Covers conductors/reduces open space to mitigate explosion risk

Encapsulated Wound Stator

  • Corrosion protection against natural gas and sulfur
  • Prevent electrical failures from debris accumulation between windings
  • Surface contour mapped to provide conformal covering of irregular end turn shapes
  • Direct shutoff on lead wires
