INTRODUCTION
• Split phase induction motor is also called resistance start motor
• The components of such motor are starting winding, main
winding, rotor, and stator
• Speed can be controlled
• Variation in the stator voltage can allows control over the speed

TWO-WINDING MACHINES
• Ideally a two winding machine
• 90º phase angle and equal mmf
• 90º physical angle between windings
