I’m testing the motor Leopard 5692 730KV. My unit is an older version (from 2 year ago, according with the manufacturer) which have a 6mm shaft. To be honest, I bought this due to lack of clear information from the listing (eBay).
I’m using a Mystery 200A ESC powered (temporary) by a 300W bench power supply (25.9V with 10Amax).
My experience from now, is as below:
- After start up, the motor is running at 2.5A without load.
- After a couple of minutes, the temperature in the surface get ~50C measured with a thermal camera.
Below some pictures during testing:
I’m concern with the temperature. A couple of questions:
- Which test you perform once you received a new motor?
- What is the operational temperature range of your motors (with and without load)?
@pacificmeister show a great picture showing the temperature (with other variables) during one of his testing (Custom Direct drive motor). The graph show ~50C as the maximum temperature with different conditions as mine (with load!).
The circular carton box came broken around the shaft (that could be the reason of the temperature situation).
