Feb 11, 1999Wye-delta open transition 3-phase motors. The following diagram is shown for 3-phase motor control of a delta-star connection. It uses three contactors, an overload relay, one auxiliary contact block, a normally open start pushbutton, a normally closed stop pushbutton, an on-delay timer of 0-20 seconds and a power supply with a fuse.
Motor controller - Wikipedia
A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against [PDF]
Wye-delta and Solid-state Starters - Rockwell Automation
The motor nameplate and connection diagram typically indicate wye-delta or star-delta, but there may also be references to low volts and high volts. The most common voltage combinations are 220/380V AC and 277/480V AC. A single-voltage wye-delta motor typically has six leads that are marked T-1 through T-6. In comparison, a standard
