Ziroth digs into Tesla's motor without rare earth magnets
Ryan Inis Hughes talked to experts and went through Tesla's technical documents, and in two days the result has outrun every other video on his recent shelf.
Why this story? The whole channel is running at 400,210 views a day, 6.6 times a normal day (60,971).
A usual day on Ziroth brings in around 60,000 views. This one brought in more than six times that, and most of the reason is a video about a motor.
"The New Tesla Motor Will Disrupt The Entire Industry" went up on Wednesday and had passed 450,000 views two days later. Its subject is a puzzle Tesla set in 2023, when the company said its next drive unit would use permanent magnets with no rare earth elements at all. That is a bold claim in a field where most electric car motors depend on powerful neodymium magnets.
The video works through it step by step. It starts with the theories circulating online, explains how permanent magnet motors work, then asks in its own chapter title whether Tesla has found "A New Type of Magnet?" The last chapter is called "Dealing with Weak Magnets," which hints at where the answer lies. In the description, Hughes writes that after speaking to experts and reading Tesla's technical documents, he thinks he has found the most likely explanation. The "disrupt the entire industry" part is the title's promise.
It caps a busy run for a channel whose about text describes its focus as projects helping the world reach a zero carbon future. In the last few weeks Hughes has covered an anode-free battery billed at 500 Wh/kg, CATL's 15-year truck battery from inside the factory, and Panthalassa's floating wave energy buoys. The anode-free battery needed about two weeks to collect a few more views than the motor video gathered in two days.
