What is yoke in dc motor?

In a DC motor, the yoke is the outer frame or housing that provides structural support and protection for the motor's internal components, such as the stator and rotor. It is typically made of iron or steel, which also serves to enhance the magnetic field generated by the stator. The yoke plays a crucial role in maintaining the alignment of the motor's parts and ensuring efficient operation by minimizing magnetic losses. Additionally, it helps to dissipate heat generated during motor operation.
