Resilient Element Transmission TRIZ Cases
- Nested Harmonic Drive Unit for Narrower Pedelec Cranksets
A harmonic drive nests the electric motor inside the flexspline to cut pedelec drive-unit width while preserving reliable power transfer.
- Pedelec Drive Unit With Nested Wave Gear for Narrow Axial Width
A nested motor-in-wave-gear layout shrinks pedelec drive unit width while preserving torque transmission, comfort, and recuperation.
