1. A small hub , upon which a series of vanes are affixed in a radial position, that is so placed that oil leaving the torque converter turbine strikes the stator vanes and is redirected into the pump at an angle conducive to high efficiency . The stator makes torque multiplication possible. Torque multiplication is highest at stall when the engine speed is at its highest and the turbine is standing still.
2. The fixed electrical windings on a magneto , alternator , or generator . It turns within the rotor . Also see variable pitch stator and thermal reactor .
