1.	What is the range of the current density for the open type motors split phase, capacitor and repulsion start motors?(a) 4-5 A per mm^2(b) 3-4 A per mm^2(c) 2-4 A per mm^2(d) 1-4 A per mm^2This question was posed to me during an online exam.I would like to ask this question from Design of Stator topic in division Design of Single Phase Induction Motor of Design of Electrical Machines
Answer» The correct option is (b) 3-4 A per mm^2 Easy explanation: The minimum value of the current density for the OPEN type MOTORS split phase, capacitor and repulsion START motors is 3 A per mm^2. The MAXIMUM value of the current density for the open type motors split phase, capacitor and repulsion start motors is 4 A per mm^2.
