Embedded linear motor drive for IR camera shutter |
| 摘要 |
An embedded linear motor drive for an IR camera composing linear motor components that integrates into a sliding shutter is disclosed. The linear motor components can be a linear array of magnets, or a series of ridges or gear teeth. A motor drive is aligned with the linear motor components. The drive can be a series of coils connected to a power source that can move the shutter when the coils are energized in series. The drive can also be a pinion shaft with a friction wheel at one end or pinion gear that can connect to the ridges or gear teeth and move the shutter when the shaft is rotated. |
