Single Phase Auto Reverse Forward Motor Control:

This Diagram Shows A forward/reverse magnetic motor starter is constructed by two regular contractors and installed with a mechanical interlock that prevents both coils from pulling in simultaneously. The Direction of Rotation of a Single-Phase Capacitor run Induction Motor is Reversed by Changing the Direction of the Rotating Magnetic field Produced by the Main and Starter Winding or Auxiliary Winding.

Components used to make the Single Phase Auto Reverse Forward Motor Control :

01. Magnetic Contactor

Fig 2: Magnetic 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. 8-Pin Timer

Fig 3: 8-Pin Timer 

Timer is a specialized type of clock used for measuring specific time intervals.An electromechanical cam timer uses a small synchronous AC motor turning a cam against a comb of switch contacts. This type of timer often has a friction clutch between the gear train and the cam, the cam can be turned to reset the time.A simple example of the first type is an hourglass. Working method timers have two main groups: hardware and software timers.Most timers give an indication that the time interval that had been set has expired.

03. Single Pole Circuit Breaker

Fig 4: Single Pole Circuit Breaker

MCB SP means single pole it protects only one phase switching. MCB (Miniature Circuit Breaker) Curswitch is the most basic general-purpose switch that you use to control a light or another device from one location. These Switches Have Two Brass-Colored Screw Terminals Connected to the hot Power Source Wires. (MCB) For any Distribution Board, the Protection System Must be Used in The Incomer. Phase and Neutral Single Phase Supply to break. 120-volt circuits, 15-20 amp single pole breaker is typically used.

Frequently Asked Questions

How can a single-phase motor be reversed and forward?

Once started, the single-phase induction motor will happily run in either direction. To reverse it, we need to change the direction of the rotating magnetic field produced by the running and starter windings. This could be accomplished by reversing the polarity of the starter winding.

How do you make the electric motor go forward and reverse?

Your DC motor could be configured to turn in either direction by simply inverting the polarity of the applied voltage. The change in the flow of current flow switches the direction of the spinning force and causes the motor's shaft to begin turning in the opposite direction.

What is forward and reverse motor control?

If a motor is to be driven in 2 directions, then it will require a Forward / Reverse motor starter, which has two three-pole horsepower-rated contactors rather than just one as in the conventional starter. Each of the two different motor starters supplies the motor with a different phase rotation.

How do you make a DC motor go forward and reverse Arduino?

To control the direction of the motor, the pins in and in two must be set to opposite values. If in1 is HIGH and in2 is LOW, the motor will spin one way, if, on the other hand, in1 is LOW and in two HIGH then the motor will spin in the opposite direction.

What is the forward direction of a motor?

By the energization of the Forward contactor coil in the control circuit diagram, the Forward contactor in the power circuit diagram got actuated which makes the motor run in the forward (clockwise) direction.
