AC vs DC Motor Comparisons
Speed Control:Speed can be controlled in both types of motor. AC motor velocity
is controlled by the frequency of the power source. AC motors run
directly off the power source and in most countries would be
designed to produce a rated speed based on an input frequency of 60
Hz. However, to vary the frequency to the motor, many applications
utilize specialized electronics (Variable Frequency Drives) to
provide adjustable speed control. DC motor speeds can be simply
controlled by varying the available DC voltage to the motor. Many
control solutions exist to provide precision speed control for
applications such as robotics.
Efficiency:Three phase induction motors tend to offer improved efficiencies at
higher power levels and rated speeds. Brushless DC motors offer
better efficiencies across a broader range of performance and
provide better performance at lower speeds and lighter loads.
Brushed DC motors, however, have added components (brushes and
commutator) that introduce some inefficiencies.
Maintenance:AC motors and Brushless DC motors are preferred in most
manufacturing settings since these motors require less maintenance
and have longer life spans in comparison to brush DC motors, which
need to be serviced more often to replace brushes or to refurbish
commutator surfaces.
Cost:AC motors are often the most cost-effective solution for large
power applications and applications with constant speed and load
requirements. Higher precision and increased load variations
introduce more sophisticated control requirements. While brushless
DC motors with higher efficiencies and additional control
complexities may have higher initial costs, their lifetime costs
are comparable to AC motors.
Starting Torque:Induction motors have minimal starting torque compared with DC
Motors that can be overcome with starting devices. DC motors offer
higher starting torques that translate to quick accelerations. Many
applications that require fast indexing and quick move and settle
times require high acceleration capabilities.
Applications:AC motors make up a large volume of electric motors sold worldwide
and are used in many applications such as household appliances,
pumps, fans, HVAC systems, and other industrial machinery. DC
motors are popular for mobile applications in electric vehicles,
automated guided vehicles, and submersible ROV’s. They are also
found in robotics, conveyor systems, packaging machinery, and many types of
precision equipment.
In recent years, advancements in motor technology have led to more
efficient and versatile options for both AC and DC motors that
sometimes blur the lines between their traditional differences.
