A brake system is disclosed, including a rotor rigidly connected to a shaft configured to rotate about a central axis. The rotor has a first side opposite from a second side, and the brake system includes a first stator structure on the first side of the rotor and a second stator structure on the second side of the rotor. The brake system further includes a first wobble plate between the first side of the rotor and the first stator structure and a second wobble plate between the second side of the rotor and the second stator structure. Each of the first and second wobble plates is configured to nutate when the first and second stator structures decrease rotation rate compared to the rotation rate of the rotor.
