Hi everyone I am trying to control two same brushless motors with ODRIVE v3.6 by following the user manual. During the initial calibration, I have problems with phase resistance and induction values. As a result, I can’t control the rotation, all attempts fail.

The motors don`t have specifications. The exact number of pole pairs, KV and other values are unknown. Info for the KYI-5T-3P from the marketplace:

Voltage:33V MAX

Max current: 13.7A

Nominal power: 450W

Max thrust: 8.1kg

prop diameter：80mm

Weight:756g

**Test date:** forward thrust

12V: current: 2.7A, thrust: 1.5kg;

14V: current: 4.3A, thrust: 1.9kg;

16V: current: 5.2A, thrust: 2.4kg;

24V: current:9.3A, thrust: 5.1kg;

30V: current: 12A, thrust: 7.0kg;

33V: current: 13.7A, thrust: 8.1kg;

**Test date:** reverse thrust

12V: current: 3.0A, thrust: 1.2kg;

14V: current: 3.7A, thrust: 1.5kg;

16V: current: 4.5A, thrust: 2.1kg;

24V: current: 7.9A, thrust: 4.2kg;

30V: current: 10.3A, thrust: 5.8kg;

33V: current: 11.7A, thrust: 7.0kg;

Perhaps some of you have already set up a similar motor or know the number of pole pairs and KV value. Or perhaps you can direct me where to find the specification for this motor. The seller couldn`t help in any way. Thanks!
