Working Principle
The working principle of a series excited motor is based on the
principle of electromagnetic induction, which generates torque
through the interaction between the armature and the excitation
winding, thereby achieving the normal operation of the motor.
Series excited motor, also known as single-phase series excited
motor, is a type of AC and DC dual-purpose motor, and its working
principle can be simply summarized as electromagnetic rotation
principle. This type of motor consists of an armature and an
excitation winding, with the armature winding connected to an
external power source and the excitation winding connected to the
armature winding. When an external power source is applied, a
magnetic field is generated inside the armature winding, which
interacts with the magnetic field inside the excitation winding to
generate an electromagnetic torque. This electromagnetic torque can
start the motor to rotate. During the operation of the motor, due
to the rotational motion of the armature winding, its internal
magnetic field will also rotate, and the magnetic field of the
excitation winding is constant. Therefore, relative motion will
occur between these two magnetic fields, resulting in induced
electromotive force. The direction of this induced electromotive
force is opposite to the direction of the current in the armature
winding, thereby reducing the total electromotive force of the
armature winding. This phenomenon is called "back electromotive
force". As the back electromotive force is related to the speed of
the motor, as the speed of the motor increases, the back
electromotive force will also increase correspondingly, and
ultimately equal to the electromotive force of the external power
source. In this case, the total electromotive force of the armature
winding is zero, and the motor is in steady-state operation.
The working principle of a series excited motor is similar to that
of a DC motor, explained by the left-hand and right-hand rules.
When powered by DC power, current enters from the left coil, passes
through the rotor winding, and flows out from the right coil.
According to the magnetic effect of current, the stator winding
will generate a magnetic field in the direction from N to S in the
diagram. At the same time, the rotor winding that receives the
current will be subjected to electromagnetic force, and the
direction of the force can be determined based on the left-hand
rule. The force acting on the coil within the range of N and S
poles is the same, but in different directions, and the
electromagnetic torque will cause the rotor to start rotating. The
combination of electromagnetic force and inertia causes the rotor
to rotate for half a cycle. Due to the presence of a commutator,
the direction of the current flowing into the rotor coil will
change, keeping the direction of the force within the N and S
ranges unchanged, and the rotor will continue to rotate.
In practical applications, series excited motors are widely used in
fields such as electric tools, kitchen supplies, and floor care due
to their advantages of high speed, large starting torque, small
size, and light weight.
