Which part of an electric motor causes the current to reverse direction?
The split-ring commutator connects the coil to the power supply and means that each time the coil rotates half a turn, the current in the coil reverses direction.
Which part of an electric motor reverses the flow direction of current in the coil after every half rotation?
The function of the commutator rings is to reverse the direction of current flowing through the coil every time the coil just passes the vertical position during a revolution. Hence, the direction of current in the coil changes in every half rotation.
Which part of a DC motor changes direction after every half rotation so that the direction of current is also reversed?
Each half turn of the armature causes the brushes to contact a new split ring, reversing the direction of current flow through the armature windings, which reverses the polarity of the electromagnetism produced in the armature.
Which motor part is responsible for switching the direction of the current every time a DC motor turns through 180 degrees?
brushless motor’s controller
To provide continuous motion, the brushless motor’s controller reverses the direction, or phase, of the current each time the motor rotates 180 degrees, or another fixed amount such as 120 degrees for a 3-phase motor.
Can you make the motor turn to the opposite direction?
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.
Which component in a DC motor reverses the flow of current in a coil?
Answer: So the commutator reverses the current inevery half turn producing a steady torque and thearmature coil rotates in a single direction.

How does a coil of wire spin in a DC motor?
The coil of wire is mounted in the gap between the two magnets. The split rings make electrical contact with the coil and reverse the current every half turn. When an electric current flows through the coil, a force is exerted on the coil, causing it to spin.
Which is part of a DC motor reverses the direction of current?
The part of the DC motor that reverses the direction of the current though the coil is the parts of the commutator that touch the brushes.
How does the current keep an electric motor spinning?
If the current in the coil were constant, the coil would stop in this position. However, to keep it spinning, the commutator breaks contact in this position. So the current stops for an instant. The momentum of the coil keeps it going and the contacts are reconnected.
How does the direction of current in a coil change?
The function of the commutator rings is to reverse the direction of current flowing through the coil every time the coil just passes the vertical position during a revolution. Hence, the direction of current in the coil changes in every half rotation. Answer verified by Toppr Upvote (0)
