Gemini Drive

A Gemini Drive compared to a regular vibration motor.

The Gemini Drive is on the left side and a conventional vibration motor is on the right side. The Gemini Drive easily outperforms the conventional vibration motor, capable of changing its vibration amplitude from zero vibration output to full vibration output in just a few milliseconds, and capable of independent control of vibration frequency and amplitude. In comparison, a single ERM can take more than 50 milliseconds to spin up or down, and its vibration amplitude can only be changed by changing its rotational frequency (speed).
