Report Survey #1 - Motors (General)

[caleb105]

I'm trying to follow all this. ;-)

I'm trying to make a list of EVERY possible option, so that I can explore the positives and negatives of all of them. From what you all have said, my options are then:

Stepper (open loop)
Stepper (closed loop w/ encoder)
Brush DC Servo
Brushless DC Servo
AC Servo (sinusoidal)
Induction Motor

Is this correct?

Thanks!

The inclusion of Induction motor would generally be for Spindle usage, they would not be selected for either open or closed loop servo use.

Thanks Al!

So, it should look like this:

Stepper (open loop)
Stepper (closed loop w/ encoder)
Brush DC Servo
Brushless DC Servo
AC Servo (sinusoidal)

Last call for any changes!?

You may ce focusing too much on motor types and not enough on drives. the electronics make a huge difference in performance especially with steppers, also tuning is very important with servos as is the chouce of encoder.

Amplexus,

Thanks for the input. Yes, I am focusing only on general motor types right now. Once I have those nailed down, the next step will be the appropriate drivers/encoders for each category.

Thanks!

how about linear motor on that list?
