Thank you to those who provided input on categories in my Survey #1 thread. I have collected those and made a list.
I now ask that you would copy the following list, paste it into your reply, and then give each category a rating of 1-10, with 10 being absolutely important in deciding, and 1 being "I couldn't care less". (also, multiple categories can have the same numeric value if they have the same importance in your mind).
There are no right or wrong answers here. I am simply looking for what characteristics YOU look for when picking a motor.
Please see the next post below for my example response. .....THANKS!
Accuracy
Closed-Loop Control
Cost (purchase price)
Current Draw
Inductance
Maintenance Cost
Noise
Power Consumption
Reliability
Repeatability
Speed
Torque
Working Lifespan

Ok, Ill bite?? Dunno why, I must be bored :) Hmmm looks like Im an On or Off type thinker. Must have one of those new fangled digital brains... JR

Hmm basicly the same as JRouche. I have been doing calculations for a huge milling machine project, and current/power draw is a big concern.
Accuracy - Agreed with JRouche. See CLC
Closed-Loop Control - 10
Cost (purchase price) - 5
Current Draw - 4
Inductance - 1
Maintenance Cost - 1
Noise - 1
Power Consumption - 4
Reliability - 10
Repeatability - Again CLC
Speed - 8
Torque - 10
Working Lifespan - 10

Thanks for the great input guys! This is really helping me get a sense of what is important to other people (which is the point of the project). I will be using all of these responses in my project, so if anyone else is willing to respond, please do so!
Thanks!
