minus-squareeleitl@lemmy.ziplinkfedilinkEnglisharrow-up3arrow-down1·3 days agoSimplicity, no transmission. As to unsprung weight, designs like these have a ridiculous power density, so add only very little. Advanced suspensions are active anyway, so just part of the wheel robot.
minus-squarelemming741@lemmy.worldlinkfedilinkEnglisharrow-up2·3 days agoThey DO require transmissions! A single speed planetary gear set is still required, same as current EV drives. Find me a hub motor datasheet with quoted power and torque below 1000 rpms. The YASA datasheets are all out to 8000 rpms. Useless at wheel speed. They’re quoting 30 second power numbers and dry weight without a gearbox. They’re fishing for dumb money.
