Motor Hub Unit with Variable-Pitch Propeller Mechanism

Prototype motor hub made with NSK’s angular contact ball bearings, thrust needle bearings, ball screws, and other NSK products. The unit features an NSK ball screw to achieve excellent motion accuracy and high efficiency.
The unit supports the rotation of the propeller and adjusts the tilt of the blades to change the direction of propulsive force quickly.

Motor speed control type flying car designs require greater thrust to maintain flight attitude, and take longer to stabilize.
NSK’s variable pitch design uses less thrust, and allows for highly responsive and stable control of flight attitude.
