Schematics For: 1 Phase Split Phase Motors - Series 3

These schematics are of Permanent Split Capacitor (PSC) Motors.

*** Part 1: Permanent Split Capacitor Induction Motors ***



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

"L1" + "L2" = Motor Input Line Leads,
"1" = Main Winding,
"2" = Auxiliary Winding,
"3" = Capacitor (always in circuit),
"4" = Squirrel Cage rotor,
"5" = AC Line Input,
"6" = Intregally Wound AutoTransformer (for speed control).




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

"L1" + "L2" = Motor Input Line Leads,
"1" = Main Winding,
"2" = Auxiliary Winding,
"3" = Capacitor (always in circuit),
"4" = Squirrel Cage rotor,
"5" = AC Line Input,
"6" = Integrally Wound AutoTransformer (for speed control).




Fig. 1.3: Speed Control Switch Detail

*Note: The AutoTransformer shown in Fig. 1.1 and 1.2 is wound onto the same "core"
as the Motor's Stator windings. Additional taps may be inserted for increased levels of speed control.
The "100%" tap is both the end of the AutoTransformer and the Motor's Lead.
Connecting directly to this lead will result in full Motor speed.
