Question

For 400 Hp 3 phase inductio motor, if bore diameter is 1 m and depth of both stator core and stator slot is 0.5m, then
outside diameter of stator is_m

A) 2
B) 3
C)1
D)4​

Answer 1

Answer:

A) 2

Explanation:

outside diameter of stator is 2m

Answer 2

The outside diameter of the stator will be 3m ( option B)

Given:

Bore diameter = 1m

Depth of stator core = 0.5 m

Depth of stator slot = 0.5 m

To find:

Outside Diameter of the stator

Solution:

We know that,

Outer diameter = inner diameter + 2*( depth of slot + depth of core)

Now, given that

inner diameter = 1 m

Depth of slot = 0.5 m

Depth of core = 0.5 m

Outer diameter = 1 + 2*( 0.5 + 0.5)

outer diameter = 1 + 2

outer diameter = 3 m

The outside diameter of stator will be 3 m.
