An in-wheel motor with a planetary reducer is the most compact and direct form of electric vehicle propulsion: the motor and gearbox are housed entirely within the wheel hub, driving the wheel directly without any driveshaft, differential, or half-shaft. This...

The electronic continuously variable transmission (ECVT) in a power-split hybrid vehicle is one of the most ingenious applications of planetary gear mechanics in modern engineering. A single planetary gear set — ring gear, sun gear, planet carrier — simultaneously...

The single-speed reducer in an electric vehicle is one of the most elegant applications of planetary gearing: a fixed ratio of 8:1 to 12:1 that matches the motor’s peak torque and peak speed to the vehicle’s traction requirements across the full speed...

Offshore wind turbines represent the most hostile operating environment for any industrial gearbox: salt spray, condensation cycling, high humidity, corrosion from marine atmosphere, inaccessibility for maintenance (weather windows of only 60–100 days per year at many...

The yaw drive on a wind turbine rotates the entire nacelle — gearbox, generator, rotor, and all — around the vertical tower axis to face the wind. A 3 MW turbine nacelle assembly weighs 60–90 tonnes and must rotate smoothly through 360° over the course of a day as...
