[sudo-discuss] Regen braking hub motor for e-bikes

Hi Sudoers: Some of you might be interested in this new e-bike hub motor with regen capability. …”Instead of mounting the disc rotor to the motor’s shell, which has been the go-to method for decades, they mounted the disc rotor to the carrier plate that holds the planet gears in the motor’s internal gearbox. It requires a slightly different shell for the motor – one that lets a mount connect the disc rotor to the gears’ carrier plate. …the disc rotor now doubles as the user-operable clutch that has always been missing. That means the motor can switch into generator mode, essentially becoming a brake as it loads the motor and converts rotational energy back into electrical energy to charge the battery. The controller and motor continuously communicate with each other, increasing or decreasing braking power according to how hard the user pulls the brake lever.” https://electrek.co/2025/12/23/weve-been-lied-to-electric-bike-motors-can-d… Seasons Greetings, -Peter
