What is another name for the frame of the stator in an induction motor?

The stator frame in an induction motor is commonly referred to as the yoke. The yoke serves several critical functions in the motor's design and operation. It provides mechanical support to the stator windings, holds them in place, and helps to form a magnetic circuit with the stator core.

In most induction motors, the yoke is made of magnetic material to ensure effective magnetic flux conduction. Its design often includes slots to accommodate the winding, and it must be robust enough to withstand mechanical stresses during operation. The term 'core' typically applies to the laminated iron structure within the yoke where the magnetic fields interact, while 'rotor' refers to the rotating part of the motor, and 'sheath' is not commonly used in this context. Thus, the use of 'yoke' clearly identifies the structural and functional role of the component in the overall functionality of the induction motor.
