Nidec

From EV motors to humanoid actuators — Nidec drives precision motion

Nidec is a global motor and drive specialist producing brushless and coreless motors, integrated motor controllers, and FLEXWAVE strain-wave gear units relevant to humanoid joint actuation. The company is a long-standing Tesla EV motor supplier now extending its technology into humanoid robot components.

Nidec's breadth spans from tiny precision motors used in consumer electronics to large traction drives for electric vehicles, giving it exceptional manufacturing scale and motor-design expertise applicable across the full range of humanoid joint sizes. Its FLEXWAVE strain-wave gear line directly targets the compact, high-reduction-ratio needs of robot joints, complementing its brushless motor and servo-drive portfolio. The company's established relationship with Tesla as an EV motor supplier creates a credible pathway for its components to appear in Tesla's humanoid Optimus program. Nidec's combination of motor technology, gear technology, and controller integration positions it to supply complete actuator sub-systems rather than discrete parts.
