3-Phase Motor Forward-reverse Switch wiring:

3 Phase Forward Reverse Switch Wiring Diagram. The forward reverse 3 phase motor control is used in a system where forward and backward or upward and downward movement in the operation is needed. The motor Forward and Reverse Operation of the motor can be obtained by interchanging any 2 of its 3 terminals.

Components used to make the motor forward reverse Switching:

01. 3-Phase Motor

Fig 2: 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.

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)

02. Overload Protector

Fig 3: Overlod Protector

Overload relays are often used to protect the motor from excessive current flow. Overload relays are used to protect the motor from overheating. Besides some specific faults such as phase to phase, phase to ground, etc. overload relay provides protection to the motor. A thermal overload relay works on the principle of bimetallic strip electro-thermal characteristics. When the bimetallic heats up, the trip function in the overload relay turns on and disconnects the power supply to the contactor coil, thus tripping the overload relay and breaking the motor current and saving the motor.
