Gagaryn I’m not knocking the Niche - a happy owner, but I reckon that price for the motor seems about right, perhaps even less when ordering in the quantities that Niche is.
There is no magic in the motor, it will be ordered to a specific specification which is what people will be referring to when they claim it is custom wound, that’s normal practice.
From the teardowns I’ve seen Niche are sourcing the motors from a variety of Chinese suppliers. I wouldn’t be at all surprised if some of these ended up on Aliexpress, often happens due to supplier overstock and also not unknown for suppliers to dump stuff on AliExpress that was rejected by the intended customers.
Just to correct some speculation.
- The motors don’t cost $5, they are more.
- Normal practice is not custom wound (and other customisations), people generally take what is the standard motors and gear it to suit, or get close to their requirements.
- I believe they work closely with1 supplier to ensure quality and specification. None of the motors for Niche are dumped on Aliexpress, or available to anyone but Niche.
I know this because I specified the exact speed I wanted the Duo motor to run at and the ratios of a planetary box could not achieve that speed with the standard offerings. It required motors running at a specific speed with a specific planetary ratio to not only give the required torque (as you know it will grind 18g of green coffee from a standing start), but also the required burr speed range for 230/240 and 110/120V. This speed required to minimise the burr overpack on grinding to reduce fines. caused by coffee grinding against itself.
All whilst delivering an acceptable grind time!
P.S. The Niche Zero also had to work at 110/120 230/240 and 100V (a side project)
