What will be the main difference for the motors of the airless paint sprayer?

Electric Piston Airless Sprayers Machines use electrical motor to drive the pump

There are three types of motors available on airless piston sprayers: AC, DC and

Universal. The following chart compares the advantages and disadvantages of

each type of motor.

Advantages Disadvantages
Universal Price is the big advantage of

Universal motors—they are less

expensive to manufacture than

either AC or DC motors.

 Although fan cooled, Universal

motors are not totally enclosed.

They have the shortest life

expectancy because they run at

10,000-20,000 RPM (3-5 times

faster than AC or DC motors).
AC A long life motor when used in

controlled conditions.

 Need constant, continuous power

supply to perform properly.

Long extension cords and

generators often cause overheating

which could permanently damage

the motor.

Maximum length of extension cord

is 100 feet.
DC The DC motor is more forgiving

of power fluctuations because it

can run at variable speeds.

Allows the user to run longer

extension cords (up to 300 feet)

and generators.

 DC motors are heavier and more

expensive.
Brushless

DC

 A long life motor in a variety of

conditions. It is more forgiving

of power fluctuations because it

can run at variable speeds.

Brushless DC motors are

smaller, lighter, more efficient,

and require less maintence over

time than DC motors.

Allows the use of longer

extension cords (up to 300 feet)

and generators.

 A heavier motor than an AC. Most

expensive motor compared to AC

or DC motors.
