What makes a "CIM" motor a "CIM" motor?

[shaneo]

Probably a n00b question, but I'm a n00b, so...

I see there are limits on the number of CIM motors you can use vs. non-CIM motors, automotive motors, mini-CIMs, etc.

But what makes a "CIM" motor a "CIM" motor? What does "CIM" stand for?

Thanks in advance -

or something....

What makes it a CIM is that it's big. Oh and it's the most powerful motor we are allowed to use.

There's a thread about the name here: http://www.chiefdelphi.com/forums/sh...d.php?t=110767

The 775pro would like a word with you.

It really is rampant in the FRC competition

It may not be the most powerful anymore, but it can still put out the highest torque and can stand generating that torque for the longest time before releasing the magic smoke.

As Mr. Forbes noted, it's big. (Not the biggest motor ever used in FRC, but the biggest currently used). There are three sealed black motors (with metal end caps) used in FRC. These motors operate well at low speeds for a pretty good amount of time before overheating.

• CIM, which is 2.5" in diameter and about 4.5" long excluding shaft
• Mini-CIM, which is 2.5" in diameter (same mounting) and about 3.5" long excluding shaft
• BAG wich is about 1.6" in diameter and 2.8" long excluding shaft

Other than the automotive motors, most of the other motors used in FRC are air-cooled, and run much faster (but with lower torque) than their sealed bretheren. Because they are lighter and air-cooled, they do not operate well at low speed for a significant amount of time.

CIMs and the other sealed motors are more likely to be used in slower "heavier" mechanisms such as a drive system or lift arm, whereas fan-cooled motors are more likely to find use powering shooter wheels, fans, high-speed intakes, and such.

I thought CIM stood for Chiaphua Industrial Motor from my browsing.

It's not just acronyms. Any word which takes on a second meaning is subject to this. Did you know that "The La Brea Tar Pits" means "The The Tar Tar Pits?" Going the other way, few are brave enough to use the name "Hawaii" to refer to "The Big Island," and they are usually misunderstood.

CCL Industrial Motor, where CCL stands for Chiaphua Components Limited.
