A couple of years ago, I bought an Ezee Original geared from Grin during a clearance sale.
Being busy, I never tried it out til now.
When I first tried it out with a sensor only controller, nothing
I haVe since tried it with two different sensorless controllers(one a Grin\Infineon) and it stumbles and studders, won't lock up.
here's what Grin says about running the Ezee sensorless:
I would contact Lyen and ask him, but he seems to be out of business.
Any ideas?
Thanx
EDIT: Well, I didn't have to search far to get some answers.
Appearantly, Lyen controllers won't work.
Looks like I will have to replace the Halls.
I have heard of some "high-speed" controllers, but have no idea what they are. Kelly controllers maybe?

Does the sensorless mode work on geared motors?
The answer to this is that it depends on the particular motor. In sensorless mode, the controllers have a safe upper commutation frequency limit of about 13000 electrical RPM. So with geared motors like the Outrider hubs that have 50 or fewer commutations per revolution they work OK, but those like the eZee, MAC, and BMC with 80 commutations per revolution are prone to loosing lock and may require sensored mode.
