What Are the Key Trade‑Offs of Using Internal Gears for High‑Performance Drivetrain Systems?
External spur and helical gears remain the mainstream industry standard for most transmission projects. Even so, internal gear setups are powering cutting‑edge modern hardware, ranging from electric vehicle hub motors to high‑load robotic joints. Well‑optimized internal gear assemblies can deliver up to 50 % reduction in overall system volume compared with equivalent external‑gear drivetrains, making them […]
