3 phase motor starter wiring diagram

3 Phase Motor starter wiring:

This circuit diagram shows 3 phase motor starter wiring diagram. In this circuit, we use a DP MCB ( Double Pole Minature Circuit Breaker ), a contactor, a motor capacitor, an NC Switch, and an NO Switch. This circuit is very simple and easy to make. If you want to know more about this circuit please check our youtube video below the post. For more learning please stay with us.

Components used to make the Motor wiring of 3 phase:

01. DP MCB

Fig 2: DP MCB

Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

02. Contactor 

Fig 3: Contactor

A magnetic contactor is an electrical device used for load control, automation, and protection. It is much like a magnetic reel. However, relays are generally used for low power and voltage, on the other hand, when we think of high power, these heavy-duty contractors only come to mind. It basically works by switching the load on and off. It has 3 terminals whose inputs are denoted as L1, L2, L3, and outputs as T1, T2, and T3. The circuit of the load is made in automation mode or protection using auxiliary contacts. It has two types of terminals. 1) Normally Open (NO). 2) Normally Closed (NC)

03. NC switch

Fig 4: NC switch

Indicates the contacts of switches or automatic actionable devices. Simply put, the push switches, magnetic contactors, and relays that we use in the factory Normally have Close Contact exists. At this moment the switch will be in normally closed condition. Because already he is sitting close. When turned off the contact will open. To make ladder logic you need to understand NC contact. As already explained. The switch contact is already closed in NC. That is enough to understand.

04. NO Switch

Fig 5: NO Switch

The operator switch has its contact in Normally Open condition. To make Ladder Logic you need to understand NO contact. A Classic Switch has one Input And one Output. In "No Switch," YoungBoy Raps About Ammunition, Murder, Firearms, and Firearm Attachments Such as a Switch. The contact of the switch whose contact is already open is NO. That is enough to understand. no switch in a circuit, then the circuit will not function as intended. to write a program such that when the red light is on, This switch is now in normally open condition. When you push the switch it will close and the red light will turn on.

05. Capacitor  

Fig 6: Capacitor

The purpose of the starting capacitor is to provide sufficient torque to start the motor and disconnect from the circuit after the motor reaches a predetermined speed. When voltage is applied to the motor without the start capacitor, the motor will make a humming sound. A start capacitor's capacitance range is between 70 and 120 microfarads. The Start Capacitor Increases The Motor Starting Torque and Allows The Motor to Cycle and run Faster. The Start Capacitor is Designed in Such a Way That it is Used for a Short Time. They cannot stay strong for long.

06. 3 Phase Motor

Fig 7: 3 Phase Motor

A Three-Phase Motor is an Electric Motor That Typically Receives its Power From a Three-Phase System (three-phase current) This can be realized via a Three-Phase Mains Supply or a Frequency Inverter. Three-Phase Motors are Available as Synchronous and Asynchronous Motors. Three Phase Alternating Current Power Motor is Economical to Supply Power to the data Center Since it Requires Less Conductor Material to Supply Electricity. This Explains Why 3 Phase Alternating Current Motor is Used in Electric Transmission, Generation, and Distribution in Most Countries Worldwide.
