n: This brake is consist of current-carrying stator and the rotator which is connected onf the drum shaft and which is rotating around the stator

n: This brake is consist of current-carrying stator and the rotator which is connected onf the drum shaft and which is rotating around the stator

n: an alternating-current motor in which the primary winding on a part (usually the stator) is connected to a source of power, and the secondary winding (usually on the rotor) carries current induced by the magnetic field of the primary winding.

n: to prevent the turbine bent or destablize or interplay friction of stator and wheel , radial direction bearing is fixed in the middle of turbine.

n: a drilling tool that is located near the bit and used to rotate the bit without having to reture the intire drill string. A spiral rotor is forced to rotate within a rubber sleeved stator by pumping mud through yhe tool. Sometimes called a moineau pump

n: a form of sucker rod pumping unit in which the rotor is a chrome-plated steel external helix and the stator is a synthetic elastomer with a double internal helix permanently bonded into a steel housing. Rotation of the rods by a vertical spindle electric motor at dte surface causes the rods to stretch a predetermined amount to maintain the rod string in tension. It also causes a cavity containing well fluid to progress upward. The system is a rotary positive-displacement unit.

n: 1. a device with vanelike blades attached to a shaft. The device turns or rotates when the vanes are struck by a fluid directed there by a stator. 2. the rotating part of an induction-type alternating current electric motor.

n: It is revolving and its blading convert the hydrodynamic to mechanical energy .

n: 1. a with vane-like blades d1at serves to direct a flow of fluid (such as drilling mud) onto another set of blades (called the rotor). The stator does not move;rather, it serves merely to guide the flow of fluid at a suitable angle to the rotor blades. 2. the stationary part of an induction-type alternating- current electric motor. Compare rotor.

n: A kind of axial flow vane wheel,which is non-tatating when system work ,its leaf blades distort according to a definite direction,its bladings have the function of diversion and energy transformation

the stationary rubber element of a PDM motor.
