1. An accelerometer comprising:
- a first stator comprising a first magnet;
a second stator comprising a second magnet;
a proof mass assembly disposed between the first stator and the second stator, the proof mass assembly comprising;
a first coil configured to receive a first amount of current; and
a second coil configured to receive a second, different amount of current; and
a controller configured to distribute the first amount of current to the first coil and the second, different amount of current to the second coil.

Abstract
An accelerometer includes a first stator, a second stator, a proof mass assembly disposed between the first stator and second stator, and a controller. The first stator includes a first magnet and the second stator includes a second magnet. The proof mass assembly includes a first coil configured to receive a first amount of current and a second coil configured to receive a second amount of current. The controller is configured to distribute the first amount of current to the first coil and the second amount of current to the second coil. The first amount of current is different than the second amount of current.
