Why are the rotor bars of a squirrel cage induction motor usually slanted i.e. not entirely parallel with the shaft?

The squirrel cage is skewed so that the force applied to the rotor it continuous. If they were straight then the force would be jerky, as whole of the bar is cutting the magnetic field lines at the same time. With the bars skewed the amount of the bar cutting the field line grows continuously and the next bar starts cutting the field lines as the first finishes.
also, slots are skewed to get uniform torque ,reduce the magnetic locking (also called COGGING EFFECT) between stator and rotor,and thirdly to reduce the magnetic humming noise during running condition

∙ 13y agoI admit to guessing, but I think it is because more surface area is exposed on the slanted surface which would decrease the resistance.

What are all the lines like parallel?
parallel lines are slanted lines
Can parallel lines be slanted too?
They can be in any direction, as long as they are still parallel to each other
Does a rhombus have 1 parallel line?
there are 2 parallel lines in a rhombus because if you think of a square a rhombus is just a slanted square
How many parallel sides does a trapizoid have?
A trapezoid has two parallel sides. The other two are slanted towards each other. In the picture below the top and bottom sides are the ones that are parallel. . ___ /____\
What is oblique lines?
An oblique line can be diagonal, sloping or slanted. It is not vertical, horizontal, parallel or perpendicular.
How does a rhombus look like?
A rhombus is 2 pairs of 2 parallel lines. An example is the diamond.
What is a quadrilateral with 2 sides parallel and only 2 sides congruent?
An isosceles trapezium or a non-isosceles trapezium in which one of the slanted sides is congruent to one of the parallel sides.
What is the definition of parallelogram?

What shape has two pairs of parallel sides and no right angles?
parallelogram... slanted rectangular box.. therefore no right angles
What is parallelogram look like?
A quadrilateral with all opposite sides parallel. A common parallelogram looks like a slanted square.
What do parallelograms look like?
A parallelogram is a four-sided shape with opposing sides being parallel. Therefore, a parallelogram may be a square, a rectangle, a rhombus (a sort of slanted square), or the shape most commonly referred to as a parallelogram is a sort of slanted rectangle. (Trapezoids are NOT parallelograms because only one pair of opposing sides are parallel)
Is it possible for the bases of a trapezoid to be equal?
No its parallel bases can never be equal in length. But if it is in the form of an isosceles trapezoid then its slanted sides are equal in length.
