Introduction
In this circuit the single phase ac motor is controlled
manually by the operator.in this circuit the motor is switched by the push
buttons. When the user press the push button then the motor will be off and the
other motor will be on. This circuit is used to change the tools of a machine
and to do other tasks on a work piece.
Apparatus
Fuse (F) 1 No.
2 overload relays (OLR) 2 No.
1 normally closed push button (NC) 1 No.
2 normally open push buttons (NO) 2 No.
2 single phase switches (S1, S2) 2 No.
1 closed switch (S3) 1 No.
2 magnetic contactors (C1, C2) 2 No.
Explanation
This circuit is controlled by the user. This is a manual
circuit. In this circuit, there are the two ways of supply and in this circuit
the user can control the motor by the two ways if the user want to change the
way of supply of the motor then he changes the way easily by pressing the
normally closed push button. This control system is operated by turning on and
off motors, valves and other devices to operate as a function of time.
