By changing the supply polarity in field winding or filed supply. Rapidly switching back and forth from forward to reverse can damage your motor.
Sh 9957 Control Forward And Reverse For A Threephase
Forward and reverse electric motor. Motor rotation is essentially created by the manipulation of wires and magnetic fields. Also in same way we can change the direction of dc motor by changing the polarity of the armature winding. A wide variety of forward reverse electric motor options are available to you such as three phase single phase. Connections in a dpdt switch resulting in a motor going forward. Reversing motors that require a lot of power can be unsafe if you dont know what you are doing. This is the main reason why ac motors are difficult to reverse.
If your motor rotates in the opposite direction than you expected or wanted simply reorient the switch in your hand so that lever is facing the bottom and then toggle the lever to the top. Field terminal consist of f1 and f2. They use an internal electronic reversing switch with no moving parts. Instant reverse motors are often used when equipment such as a gate mechanical door or hoist needs to move in two directions with minimal delay in starting. Forward reverse of dc motor. Thus you can often reverse ac motors by switching the wire connections.
When the switch lever is in the top position the motor rotates forward. Instant reverse motors are designed for applications that need instant reversibility with moderate starting force. This is as easy as unhooking and re crimping the designated wires. Note not all ac motors have the ability to be reversed but all of groschopps ac motors can be.
