Question
Download Solution PDFThe loss that takes place due to winding resistance is called ______.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- The winding losses taking place during the current flowing through the winding are known as Copper losses.
- Copper losses are directly proportional to square of the current.
- These are variable losses dependent on load current.
- Windage losses are the losses sustained by a machine due to the resistance offered by air to the rotation of the shaft.
- These are mechanical losses and independent of load.
- As the armature core of electrical machine is made of iron and it rotates in a magnetic field, a small current gets induced in the core.
- Due to this current, eddy current loss and hysteresis loss occur in the armature iron core.
- Iron losses are also called as core losses or magnetic losses.
- These are constant losses and independent of load.
