  • The magnetic field is produced using electromagnets carefully positioned at different locations in the stator.
  • rotor and stator
  • stator vane
  • stator winding

Examples

  • Many EVs run on induction motors, which have two main parts, a stator and a rotor.

  • Energizing the stator causes the rotor to oscillate between the two positions.

  • The 11000 Series is made with few parts and only one stator phase.

    Academic text (1995)
  • The equal wall stator reduces starting torque and is said to allow twice the pressure.

    Academic text (1996)
  • For a simple generator, the stator may have two field magnets on opposite sides.

    Academic text (2008)
  • The generator itself has two basic parts: the stator, which is stationary, and the rotor, which rotates.

    Academic text (2008)
  • To minimize the rotor and stator losses that result from stator teeth, engineers used an air-gap wound stator.

    Academic text (1995)
  • The rotor rotates as its currents interact with the stator's revolving magnetic field.

    Academic text (1995)
  • In a typical motor, the stator is the stationary part that surrounds the rotating rotor.

  • The stator consists of coils that create a magnetic field when electricity flows through them.

Etymology

Stator comes from the Latin root stare, which means 'to stand' and is like the English word 'stand' or 'stationary'. A stator is the part of a motor that stays still while the rotor moves, so the name means the 'standing' or fixed part.
