AC gear motors and DC motors each have their own distinct characteristics, applications and benefits. However, when you need to make a choice between the two, you may find the AC gear motor to be far superior. The following is a look at some of its advantages.

Size: An AC gear motor is generally smaller and lighter in weight.

Cost: DC motors can be more expensive to purchase and maintain.

Durability: AC gear motors are more rugged, particularly in wet, hazardous, potentially explosive and corrosive environments.

Speed: AC motor speeds are more precise and can control multiple motors, reach speeds of up to 10,000 rpm (or 1000:1) and maintain the ongoing horsepower needed at above 150 percent of the base speed.

Drives: AC drives have tight speed regulation, adjust well to fast-changing loads and, in closed-loop systems, can regulate speeds to within 0.01 and less.

Operation: AC gear motor drives can reach full torque upon startup and work well when you need constant ongoing torque below 50 percent of the base speed.

Energy efficiency: Insulated premium-efficient AC gear motors operate at cooler temperatures than DC motors.
