| Lowest electrical noise type of motor for low speed applications |

Hi, what type of DC motor (up to 12V) has the lowest inherent electrical noise (both transmission and emission)? I mean by design (i.e. without considering any shielding or filtering I might add later). Ideally I am looking for a direct drive at a speed from 1 RPM to 200 RPM which I can control via a micro or a pot. If that's too low then I can use a gearbox. Load/torque is very minimal and not a concern and the same for acceleration/deceleration. I just need to rotate a light plastic plate. Thank you |

If you have AC available, I'd say a shaded pole motor. |

Would a clockwork motor be acceptable? They don't generally have much in the way of electrical noise |

These are 'clockwork' in British English. A shaded-pole, or synchronous, AC motor would be OK, but you still have the possibility of mains-borne interference. |
