Hey All
I have a Bartech Focus Device, but no working motor. I am looking to buy a used motor, and I understand that I can use any of the following...

Palomar Engineering: M-One. M-One .5 Focus

Heden: M26P, M26PT, M28VP*, M28VPT*, M32P, M32PT, M21VP*
* requires a no-cost modification to the BFD for optimum performance

Stanton: Right angle motor (requires a no-cost modification to the BFD to prevent motor damage)

Cinema Products: ZB-100, SLD-100

SPF: FMG-6

But which? Can anyone suggest a standout amongst these?

Thanks!

I use the Stanton RA motor with my BFD. Works perfect and is fairly quite.

Skip the following FMG-6, anything Cinema Products and the Stanton

Buy either the M-One or a Heden

Bottom line is ONLY purchase something that is Current, Has good service and is common to your market. Buy Quality once, don't delude yourself into the false economy of buying the "Cheaper" motor, because it WILL break, you WON'T get service and then you WILL buy the higher priced higher quality motor.

Fairly quiet doesn't work when you're shooting a closeup and the motor is Whiring away

Thanks Guys! I'll be on the hunt for a M-One for sure. That was my gut instinct, anyway.

One thing about the Stanton motor BFD mod, although reversable, it "breaks" compatibility with other motors. So if your motor goes down, you may not be able to borrow a compatible backup. That said, the Stanton motors are cheap enough maybe you could buy a backup. But as Eric pointed out, they are noisy and so are very limited for wireless FF applications.

What is the modification for some of the Heden motors?

The Heden M28VP is another nice motor to consider. Not as powerful as the M-One but a good solid motor.

The servo loop gain must be increased due to the different performance characteristics of the M28VP or M21VP motors. The older M26P motors are just fine. The modification requires changing 4 resistors. I charge $25 in labor for existing units and include it at no charge on new units.

Jim,

Did I correctly state the situation with the Stanton motors?

I have the M28VPT motor, and BFD which I believe you verified had been previously modified. How does this mod affect compatibility to other motors (M-One, M26PT, etc)?
