Short description:  

Certain applications for 3-phase AC machines such as indirect control of mixer, require additional levels of control to obtain a desired outcome. This training module will cover issues relating to advanced control AC 3-phase machines in a targeted fashion.

Contents:    

• Contactor circuit for controlling a 3-phase motor.
• Wiring and function of self-holding circuit.
• Problems associated with a reversing contactor circuit.
• Layout of a 3-phase motor for star-delta start startup 230 V/400 V.
• Wiring and function of a timer relay.
• Set-up of a reversing contactor circuit with automatic star-delta start-up.
• Speed control of AC-motors using a frequency convertor.
