What is the best type of DC motor for use with DC?

Answer 1

Basically anything that works with batteries usually works with DC motors, i.g. your hard drive, your cellphone vibrator, toys, etc.

Also, even for large motors, the DC motor has the advantage of being easily controlled by input voltage. Induction motors, on the other hand, can use controlled input voltage but they will have to deal wth low torque when the voltage is low.

DC motors are used for those little fans in your computer. Also, CD players also use DC motors to spin the discs. DC motors are important where absolute speed control and feedback are necessary.

For your household appliances, including fan motors, those are AC motors, cheaper for the industrial strength and more efficient.

Answer 2

DC motors are used in applications that the connected load has to have its speed controlled. DC motors are not as prevalent as they used to be with the advent of Variable Frequency Drives. Through the VF Drive, AC motors speed can be regulated even better that DC motors with a lot less control equipment that DC motors need.

Answer 3

I think that separately excited dc motors are best for d.c....
