Das Angle 6 Click Board™ ist eine kompakte Zusatzplatine, die die absolute Winkelposition eines Permanentmagneten erkennt, typischerweise eines diametral magnetisierten Zylinders auf einer rotierenden Welle. Diese Platine verfügt über den MAQ470GQE, einen kontaktlosen 12-Bit-Winkelsensor mit PWM-Ausgang von Monolithic Power Systems. Es unterstützt viele magnetische Feldstärken und räumliche Konfigurationen, wobei sowohl Konfigurationen am Wellenende als auch außerhalb der Achse (Seitenwellenmontage) unterstützt werden. Schnelle Datenerfassung und -verarbeitung ermöglichen genaue Winkelmessungen bei Drehzahlen von 0 bis 60.000 U/min sowie die Erkennung der magnetischen Feldstärke mit programmierbaren Schwellenwerten. Dieses Click Board™ bietet eine äußerst zuverlässige und kontaktlose Methode zum Messen von Winkeln, Positionen und Geschwindigkeiten verschiedener Anwendungen.
Das Angle 6 Click Board™ unterstützt die mikroSDK-kompatible Bibliothek, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ ist ein gründlich getestetes Produkt und kann auf einem System verwendet werden, das mit der mikroBUS™-Buchse ausgestattet ist.
How Does The Angle 6 Click Board™ Work?
The Angle 6 Click Board™ is based on the MAQ470GQE, 12-bit PWM output angle sensor that detects the absolute angular position of a permanent magnet, typically a diametrically magnetised cylinder on a rotating shaft from Monolithic Power Systems. It allows users to read angle position information and detect the speed or direction of magnet rotation. Fast data acquisition and processing provide accurate angle measurement at rates from 0 to 60,000rpm. It supports many magnetic field strengths and spatial configurations, with both end-of-shaft and off-axis (side-shaft mounting), supported configurations.
The MAQ470GQE features magnetic field strength detection with programmable thresholds to allow sensing of the magnet position relative to the sensor to create functions such as sensing axial movements or diagnostics. It can operate over a wide magnetic field range from 30mT to 150mT (60mT typical) with 5mT accuracy. Eight magnetic field thresholds are programmable in approximate 15mT steps allowing detection of changes in the distance between the magnet and the sensor. On-chip non-volatile memory provides storage for configuration parameters, including the reference zero angle position and magnetic field detection thresholds.
The magnetic field is detected with integrated Hall devices located in the sensors' centre. The angle is measured using the Spinaxis™ method, based on phase detection generating a sinusoidal signal with a phase representing the angle of the magnetic field. The angle is then obtained by a time-to-digital converter, representing output from the front-end to the digital conditioning block, which measures the time between the zero-crossing of the sinusoidal signal and the edge of a constant waveform. This output delivers a digital number proportional to the angle of the magnetic field at the rate of 1MHz in a straightforward and open-loop manner.
The Angle 6 Click Board™ communicates with MCU using the standard SPI serial interface for angle reading and register programming, which supports SPI Mode 0 and 3 and operates at clock rates up to 25 MHz. It also has the magnetic flags used to indicate when the sensor position's magnetic field is out of range, defined by the lower and upper magnetic field thresholds, routed on the RST and INT pins of the mikroBUS™ socket labelled as MGH and MGL.
The Angle 6 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
