Question 11

A technician is developing the motor for a laboratory sample mixer. A test winding has 24 turns and carries a current of 0.50 A.

The new winding must produce 1.5 times the total turning effect of the test winding. Each candidate winding has the same dimensions as the test winding and operates in the same position between the same magnets.

For these windings, the total turning effect is proportional to the number of turns multiplied by the current.
