Series-wound electric motors ________.

Series-wound electric motors are designed in a way where the field windings are connected in series with the armature windings. This means that the same current flows through both the field and armature, which is a key characteristic of this motor type.

At zero RPM, the motor can produce maximum torque because the field strength is at its maximum since the current flowing through the series windings is the same as that in the armature. As the speed increases, the back electromotive force (EMF) also increases, which reduces the net current in the motor. Thus, while high RPM results in lower torque, at 0 RPM, the motor offers maximal torque capacity due to the high field strength generated by maximum current.

Therefore, it is accurate to say that series-wound electric motors produce maximum power at 0 RPM, as they excel in providing high starting torque, which is particularly useful in applications requiring substantial initial movement.
