Basic Start/Stop AC Motor Control Schematics
The following Drawings / Schematics demonstrate Basic Start & Stop Control Circuitry for 3 Phase, Squirrel-Cage Rotor type AC Induction Motors.
-------------------------------------------
A: Full-Voltage Start / Stop Control
-------------------------------------------
Schematic #1: Full-Voltage Start / Stop ("3-Wire") AC Motor Control;
Control Circuit = Line Voltage (Motor Voltage).
..........
Schematic #2: Full-Voltage Start / Stop ("3-Wire") AC Motor Control;
Control Circuit = Low Voltage (via Transformer connected to Motor Circuit).
..........
----------------------------------------------
B: Basic Wye-Delta Start / Stop Control
----------------------------------------------
Schematic #3: Wye-Delta Reduced Voltage Start / Stop Motor Control.
..........
