Automotive planetary gears are compact and highly efficient gear systems consisting of a central sun gear, multiple orbiting planet gears, and an outer ring gear. They are extensively used in vehicle transmissions, differentials, and electric drive units to provide multiple gear ratios, improved torque distribution, and efficient power transfer. The growing adoption of automatic transmissions and electric vehicles (EVs) has significantly increased the demand for highperformance planetary gear systems.
The global Automotive Planetary Gear market was valued at US$ 3.12 billion in 2024 and is projected to reach US$ 4.04 billion by 2030, growing at a CAGR of 4.4% during the forecast period.
The United States market was valued at US$ 687.5 million in 2024 and is projected to reach US$ 867.3 million by 2030, registering a CAGR of 4.0%. The market's expansion is attributed to the increasing shift toward fuelefficient automatic transmissions and electrification trends in the automotive industry.
