I have a RS-555SH Motor and downloaded the datasheet for it and see it comes in a number of voltages. The one I have is either 12V or 24V. How can I know which voltage it is? Besides the one page datasheet, this is what I know: It runs on 5V slow and weak and obviously not the right voltage. 12V decent speed and power. 24V fast and powerful. This is going to be used for a fan, so the more power the better. Thank You! |

Spin the motor at a known RPM, eg, with an electric hand drill, and measure the voltage at the terminals. Both types have an rpm of ~6400 at nominal voltage (12 or 24 V). Example: If your hand drill has an RPM of 1500, the generated voltage will be either 1500/6400 x 12 V (~2.8 V) or 1500/6400 x 24 V (~5.6 V). |

Brilliant! I have something that measures rpms. I can use a ESP32 to adjust (using PWM) the rpms. This makes so much sense that I failed to see it. Thanks so much! |
| Benta:
I didn't mean drive the motor electrically I meant spin it mechanically with another motor, eg, power drill. |
| vidarr:
Yeah, I understood that. I have another motor I am going to hook to the RS-555SH Motor to drive it. Thanks! |
