Product Description

Encoders in the SimpleBGC project
Using encoders with SimpleBGC board gives the following advantages:
1. Prevents motors from losing synchronization and skipping steps.
2. Provides the information about frame angle and angle of the camera relative to the frame, that can be
important for some kind of applications.
3. Can significantly decrease power consumption by using field-oriented control strategy to drive
4. Increases instant torque in 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 the camera position by hands.
7. Increase the precision of stabilization by applying for FOC-specific compensations.
Despite the implementation of some new features is still in progress, encoders now give completely new
feel of operating the system, and recommended to use in the professional-grade products.
List of supported encoders
AMT203 – absolute (capacitive technology) 12bit, SPI communication
AS5048A, B – absolute (magnetic) 14bit, PWM, I2C or SPI communication, not assembled.
MA3 – absolute (magnetic) 10-12bit, assembled. PWM communication.
Analog – potentiometer or any other type where the analog output is proportional to the angle
AS5600** – absolute magnetic encoder with Analog, PWM or I2C interface
SBGC32_I2C_Drv expansion board – acts as an external motor driver combined with encoder interface,
controlled by an I2C bus. See for details.
Type of encoder can be selected during the tuning process in the GUI.
There is no big difference between 12bit and 14bit resolution because encoders are not used in the
closed-loop PID controller, so high resolution is not strictly required. But ABSOLUTE angular error should
be as low as possible, especially with the big number of poles.

The AS5048 is an easy-to-use 360° angle position sensor with a 14-bit high-resolution output. The maximum system accuracy is 0.05° assuming linearization and averaging is done by the external microcontroller. The IC measures the absolute position of the magnet’s rotation angle and consists of Hall sensors, the analog-digital converter, and digital signal processing. The zero position can be programmed via SPI or IC command. Therefore no programmer is needed anymore. This simplifies the assembly of the complete system because the zero position of the magnet does not need to be mechanically aligned. This helps developers to shorten their developing time. The sensor tolerates misalignment, air gap variations, temperature variations and as well as external magnetic fields. This robustness and wide temperature range (-40°C up to +150°C) of the AS5048 makes the IC ideal for rotation angle sensing in harsh industrial and medical environments. Several AS5048 ICs can be connected in the daisy chain for serial data read out. The absolute position information of the magnet is directly accessible over a PWM output and can be read out over a standard SPI or a high-speed IC interface. Version AS5048A comes with SPI and PWM Interface. Version AS5048B is configured with the IC interface and has also a PWM output. An internal voltage regulator allows the AS5048 to operate at either 3.3 V or 5 V supplies.

It is specially designed for iPower Motor GBM5208 GBM6208 GBM6212 GBM8017 GBM8028 GBM8108 GBM110 Motor, Please note that there should be screw holes on the gimbal motor to fit the metal mounting plate, otherwise you'll need to DIY to mount. The dimension of the aluminum alloy part is shown below.
