Introduction
In this article you will know the sequence control of two ac
motors at a time. In this circuit two ac motors are controlled using only one
time relay and with one time operated switch. This circuit is used to change
the tools of a machine and to do other tasks on a work piece etc.
Apparatus
Fuse (F) 1 No
Overload Relays (OLR) 2 No
Normally Closed Push button (NC) 1 No
Normally open push buttons (NO) 1 No
Single phase Switches (S1, S2, S3) 3 No
Magnetic Contactors (C1, C2) 2 No
Time Relay (TR) 1 No
Time Switch (TS) 1 No
Explanation
In this circuit the two single
phase ac motors are controlled using time relay. In this circuit the motor
starts running by pressing the push button. When the motor starts running then
the time relay will start counting and then cut off the current of the motor
according to the time which will set in time relay and then connect the supply
to the other motor to operate the switch.

Uses
The use of this circuit is in manufacturing
industries or manufacturing plants to change the operation, tools to design a material,
shape or to do other operations on work piece.
