Textbook Question
Chapter 26, Problem 1RQ
Name two requirements that must be met before a motor can be used for wye-delta starting.
Expert Solution & Answer
To determine
Identify two requirements for a motor to be used with wye-delta starting.
Explanation of Solution
Wye-delta starting is used to reduce the inrush current and the starting torque. The two requirements for a motor to be used with wye-delta starting are:
- The design of the motor must be such that the stator winding is connected in delta during the running time.
- All the leads of the stator windings must be accessible.

Given data:
a= 10 cm.
L= 10 cm.
b= 20 cm.
H=40cm.
⚫ a = 10, cm: This could represent the width of the duct.
⚫b=20, cm: This might be the height of the duct.
⚫L = 10, cm: This usually stands for the length of the duct in
the direction of flow.
⚫H=40, cm: This could indicate the height of some
component or another duct-related dimension, but the exact
meaning depends on the experiment's context.
please explain each step and include drawings on the phase diagram. thanks
