When using a 3 wire control circuit to control a magnetic motor starter the part that will open the control circuit when an overload occurs will be?
The part that opens the circuit is the overload blocks that are situated below the magnetic starter and before the motor load. The latest addition to the electrical code book states that the "hot" wire goes through the overload contacts first before feeding the 3 wire control system. With the supply voltage in this position the whole circuit becomes de-energized when the motor load trips the circuit. The old standard practice on a 3 wire control system, the neutral was connected to the overload relay contacts. When the overload relay tripped it opened the neutral of the coil circuit and the starter dropped out
How can you include phase failure relay in your star delta motor starter circuit?
The star delta motor starter circuit has to have a control voltage to energize the motor magnetic contractors. A phase failure relay monitors all three phases of the incoming supply lines. The phase failure relay also has auxiliary contacts on it. There are usually two sets of "C" form contacts. The control voltage for the starter circuit must be connected across the normally open (N.O.) contacts of one of these two sets. When the phase monitor is energized these N.O. contacts close supplying the control voltage to the circuitry of the star delta starters. If there is a phase interruption, phase reversal or phase loss, the phase failure relay will de-energize and the N.O. contacts will go back to their de-energized state. If the star delta motor starter is in use at the time, its control circuitry voltage will be lost and the delta motor magnetic contactor will open. The opening of this contactor will disconnect the motor from the failed three phase supply.
Why do you need a motor in a circuit?
to turn electrical potential into mechanical work/motion.
What are examples of a load in a circuit?
Any specific device that draws a current which is connected within the circuit is an example of a circuit load. That may be a resistance and a loudspeaker LED computer and induction motor or whatever which can withdraw the energy from the output.
Can you wire a Dayton electric motor to run backwards?
Yes, just reverse the start winding circuit.
Which is not a type of home circuit?
A three phase motor control circuit.
What are convectional and non convectional methods of speed control of a induction motor?

What is an electric circuit that controls another electric circuit through a relay?
Remote-Control Circuit. Any electrical circuit that controlsany other circuit through a relay or an equivalent device.
What is common methods control speed dc motor?
there are two methods i.e armature control method and field control method....
How do you choose circuit breaker all the control circuit if i have 50kw power of motor?
The breaker should be sized to 250% of the motor's full load amperage.
Why you use cartridge fuse in control circuit of motor?
It is proper "control sense" to fuse the control circuit. It does not have to be just a cartridge fuse, in many cases it is a breaker. Depending on where the control voltage is obtained from, transformer from the incoming motor feed, separate source, or line voltage, there is always a chance that a component of the control circuit could fail, circuit protection would lessen the damage to other equipment in the control circuit. The fuse should be sized as close to the control current as possible.
In what two ways can the speed of a dc motor be varied?
speed of a dc motor can be varied by mainly two methods:- 1)field control method 2)armature control method further , field control method can be divided in 3 parts:- 1)field rhestat control method---speed variation is acomplished by means of a variable resistance inserted in series with shunt field 2)reluctance control method---by changing the reluctance of magnetic circuit by choosing right material.. 3) field voltage control method-requires variable field voltage supply. and armature control method can be divided in 3 parts :- 1)armature resistance control---variable resisitance connected in series with armature 2)shunted armature control. 3)armature voltage control. ------------mrityunjay pandey (kiit university ,btech 2nd year)
