AC AND DC MOTORS
Assignment Two
Although the AC and DC motors convert electric energy to mechanical energy, they
possess specific differences in certain features. These differences are evident in input power,
magnetic field, speed control, startup mechanism, and performance. Thus, the subsequent
paragraphs will explain the discrepancies in the above features.
•
Input power; AC motors are operated from the bidirectional power source. Thus, they
can be performed using the single-phase power source or the three-phase power source
(Barinov, & Melnichenko, 2019). Conversely, DC motors are driven by a unidirectional
current supplied from a direct current source.
•
Magnetic field: the stator coils in the AC motors are supplied with an alternating current,
which produces a rotating magnetic field (Barinov, & Melnichenko, 2019). In DC
motors, a set of field coils or a permanent magnet make a magnetic field devoid of
rotation.
•
Speed Control: The motors' speed in AC motors is controlled by the input frequency of
the alternating current generated by the stator coils. The speed is directly proportional to
the input frequency (Barinov, & Melnichenko, 2019). Conversely, DC motors' speed is
regulated by the fluctuating current and voltage in the armature coils (Barinov, &
Melnichenko, 2019).
•
Performance: AC motors are highly preferred due to their high variable torque and high
speed. On the other hand, DC motors are preferred where speed control is needed.

Assignment Three
The DC motors operate by converting electrical energy into mechanical energy through
rotation. The physical behavior of electromagnetism influences the high-speed circuit. The
Direct Current motors have inductors which ...
