It would be surprising if the motors wouldn’t be more powerful with more powerful magnets. They make curved neodynium magnets. Seems like a fundraising angle, but performance will speak for itself.
By using a greater mass of magnets, placed farther out on the spinning plates, and spinning those plates at a higher speed than is typical, Conifer has managed to use weaker iron-based magnets
The article mentions that these particular iron-based magnets are weaker, but I wonder if they could use iron nitride magnets, which are apparently on par with rare neodymium magnets.
