How to Reverse Your DC Motor. Your DC motor can be configured to turn in either direction by simply inverting the polarity of the applied voltage. The change in the flow of current switches the direction of the spinning force, causing the motor’s shaft to begin turning in the opposite direction.
How does a motor go in reverse?
In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation.
What happens if you turn a DC motor backwards?
If you try to stop or reverse it manually, then it will try to draw whatever current is needed to continue running at that speed. The high current could heat the motor to the point of damage, unless the power supply limits the current.
How do you change the direction of a DC motor?
The direction of rotation of DC series motor may be reversed by changing the polarity of either field or the armature winding.
What are Interpoles in a DC motor?
An auxiliary set of field poles carrying armature current to reduce the field flux caused by armature reaction in a d-c motor. Interpoles – Are coils that are placed between the field coils that generate a field that is used to prevent excessive sparking of the brushes.
How do you make a motor go forward and reverse?
Remove power from the motor. Hook the battery positive wire to the negative terminal and hook the battery negative wire to the positive terminal for a simple DC motor. Install a double pole double throw changeover switch between the battery and the motor. The motor will now have a forward, reverse and an off position.
Which DC motor is reverse current?
Answer: So the commutator reverses the current inevery half turn producing a steady torque and thearmature coil rotates in a single direction.
