Schematics For: 1 Phase Split Phase Motors - Series 1

These schematics are of Split Phase Resistance Start Motors.

*** Part 1: Resistance Start Induction Motors- Single Winding ***



Fig. 1.1: Resistance Start Induction Motor Circuit Diagram-C.C.W Rotation (normal rotation)

"L1" + "L2" = Motor Input Line Leads,
"1" = Run (Main) Winding,
"2" = Start (Auxiliary) Winding,
"3" = Centrifugal Start Switch,
"4" = Squirrel Cage rotor,
"5" = AC Line Input.




Fig. 1.2: Resistance Start Induction Motor Circuit Diagram-C.W Rotation (reversed rotation)

"L1" + "L2" = Motor Input Line Leads,
"1" = Run (Main) Winding,
"2" = Start (Auxiliary) Winding,
"3" = Centrifugal Start Switch,
"4" = Squirrel Cage rotor,
"5" = AC Line Input.

*** Part 2: Resistance Start Induction Motors- Split Winding, Low Voltage Connection ***



Fig. 2.1: Resistance Start Induction Motor Circuit Diagram-C.C.W Rotation (normal rotation)

"L1" + "L2" = Motor Input Line Leads,
"1a" + "1b" = Run (Main) Winding,
"2" = Start (Auxiliary) Winding,
"3" = Centrifugal Start Switch,
"4" = Squirrel Cage rotor,
"5" = AC Line Input.




Fig. 2.2: Resistance Start Induction Motor Circuit Diagram-C.W Rotation (reversed rotation)

"L1" + "L2" = Motor Input Line Leads,
"1a" + "1b" = Run (Main) Winding,
"2" = Start (Auxiliary) Winding,
"3" = Centrifugal Start Switch,
"4" = Squirrel Cage rotor,
"5" = AC Line Input.


*** Part 3: Resistance Start Induction Motors- Split Winding, High Voltage Connection ***



Fig. 3.1: Resistance Start Induction Motor Circuit Diagram-C.C.W Rotation (normal rotation)

"L1" + "L2" = Motor Input Line Leads,
"1a" + "1b" = Run (Main) Winding,
"2" = Start (Auxiliary) Winding,
"3" = Centrifugal Start Switch,
"4" = Squirrel Cage rotor,
"5" = AC Line Input.

"L1" + "L2" = Motor Input Line Leads,
"1a" + "1b" = Run (Main) Winding,
"2" = Start (Auxiliary) Winding,
"3" = Centrifugal Start Switch,
"4" = Squirrel Cage rotor,
"5" = AC Line Input.
