I've been searching FF motors for my G25 for months and i can't find one new to buy yet. This happens becouse the FF motors are very specials. They have very low "detent" or "cogging" efect (just try to spin a simple electric motor with your fingers and you will feel that the motor goes in "steps" that's the "cogging" effect and that's affects your FF experience)
I wrote to Jhonsson Electric about acquire new motors for my G25, and they said:
"Dear Sir,
Thank you for visiting our website and inquiring about the availability of one of our products. All of Johnson Electric’s products are custom designed to match the specific requirements of our customers. The final product or model of our customer is in many cases unknown to us, since major global companies utilize the same component across different brands. Unfortunately, since these custom components are made to order, Johnson Electric does not hold inventory for replacement parts.
Johnson Electric manufactures these components in very high quantities for hundreds of global brands, who manage their own warranty programs independently. Our website is designed to feature standard platforms that could be modified to suit an equipment makers performance requirements, the website is not configured for online sales. Johnson Electric also has a distribution network that carries some of the more commonly used items. This distribution channel is also focused on the industrial segment and serves lower volume equipment makers. You may want to check with one of the distributors in your area regarding availability of the part you are looking for. "
Finally, the only way is buy a used motor from a old or broken DFP, or in my case from a G25.
So, if anybody has an extra G25 motor, i'll be pleased to buy it
