Abstract
- Wheel drive electronics is a brushless direct current motor control module attached to the reaction wheel used to control the satellites' attitude. At the development stage, this module needs to be verified at the component level. However, with the many electronics system factors in this module, the measurements are conducted partially, which implies increasing the testing time consumption. For this reason, an automatic measurement system was developed. One part of it is the data acquisition hardware. This data acquisition is used to retrieve data from sensors, convert analog signals to digital, and send data to computers to store, manipulate, and display data. This data acquisition hardware mainly uses Arduino DUE based on Atmel SAM3x8E ARM Cortex M3 and ADS1256 as an analog to digital converter with 24-bit resolution. This device is modular and integrated. Modular means that it can be replaced easily due to damaged or for obtaining better performance. Integrated means that it comprises various sensors that support the automatic measurement method. This device is also equipped with a relay to protect it from the excess current flowing into this module. After that, the obtained sensor data will be sent parallelly to the computer through a format data that contains measured information, sensors data, and sampling time. These data are used to compare and check the wheel drive electronics system's properties, such as stator current, motor speed, power consumption, temperature, and voltage, especially back-EMF. From the results, the stator current error is ±4.6%, the back-EMF voltage error is ±0.1775%, the power consumption error is ±4.61%, the temperature error is ±1°C, and the motor speed resolution is ±0.05 RPM.
