They are AMT motors made in germany. They dont sell them to individual unless you bulk order. But they are used by sunrise medical, amy systems, handycare powerchairs etc etc. So you look for a chair available locally and order as spare parts. But they are no less or more reliable than any other 4 pole motor. Eg linix, electrocraft, etc.
