Testing Alexmos SimpleBGC with Encoders Firmware 2.44B4

Brushless Gimbal Motor with encoder for Alexmos SimpleBGC

 

Motors with SPI/PWM  Encoders

 

 

New Alexmos Encoder Firmware Upgrade

Using encoders with SimpleBGC board gives the following advantages:

1. Prevents motors from loosing synchronization and skipping steps.

2. Provides the information about frame angle and angle of the camera relative to frame, that can be

important for some kind of applications.

3. Can significantly decrease power consumption by using field-oriented control strategy to drive

motors.

4. Increases instant torque the same way.

5. Provides possibility to get information about the camera balance and makes automatic balancing

(with help of extra DC servomotors and moving counterweights).

6. Option to adjust camera position by hands.

7. Increase the precision of stabilization by applying FOC-specific compensations.
