Can you explain what a lost motion spring is? When I search for it, I see results about a recall for lost motion springs used in cars, but not about what it actually is or how it works.

I would agree with Allen... It's a gray area, and I would probably pass it (pending any relevant Q&A or rule changes). The rules on automotive motors are rather vague this year. Bring a datasheet that specifies the automotive use for the motor, which I think you already found.

Congrats on finding a really cool off the shelf assembly!

It's a pretty nifty solution, but for that price tag I personally would use something else.

However each team has their own priorities, and two LRIs have weighed in, so good on you.

I have just managed to speak to a tech rep for the actuator and it is indeed an automotive motor. The motor manufactures web site states " These motors are commonly used for RV and truck step lift assemblies, window lift, awning extension, and many other applications". Its listed under wiper systems.

This is the motor -



The motor and actuator are available separately or as an assembled unit.

With that said should we buy them separately and self assemble or does having a data sheet for the motor assembly stating its automotive heritage suffice to meet the rules? This is were experience wins the day!

Thanks again for all your input.

Where you ever able to get the motor part number from the supplier? Then you could look it up and see if there is a datasheet or documentation to show it is used as a window motor.
