AS5047D-ATSM

Encoder is an electromechanical device, which is used to measure the rotational angular positions and rotational speed. It can also measure other linear and angular positions and transmission positions. Generally, an encoder is composed of a sensing element and a rotary position detector. The sensing element consists of a disc, a shaft, a set of optical components, a plastic housing, and some signal processing devices. The purpose of the sensing element is to detect the rotation of the rotor, and convert the angular displacement into a measurable electrical signal or a digital signal.

AS5047D-ATSM is a type of encoder used for angle measurement and rotation speed detection. It is a programmable angular position sensor IC which is capable of measuring positions over a range of 360°. It is a high precision position sensor which can detect the position of a brushless DC (BLDC) motor accurately. It is highly integrated, with a SPI interface and 14-bit resolution. The sensor includes on-chip diagnostic functions, allowing simple commissioning and diagnosis of BLDC motor. It is fully programmable and can be used in a variety of applications, such as automotive, office automation, robotics and industrial.

The working principle of AS5047D-ATSM is based on the use of Hall effect sensors to measure the magnetic fields generated by the rotor. The Hall effect sensor consists of two electrodes with an electrical resistance of the order of 1 ohm. The Hall effect sensor is placed such that the magnetic flux is concentrated around the small contact point between the two electrodes. The resistance of the Hall sensor then changes due to the rotation of the rotor. This variation in resistance is then converted into a digital signal, which is then transmitted to the motor controller for calculations.

The AS5047D-ATSM is designed to provide accurate and reliable angle measurements. It is able to detect angles of up to 360° and offers a resolution of up to 14-bit, meaning that it is able to detect even the slightest changes in angular position. It also offers diagnostics features such as detect slips, track movement, detect failure of motor or power supply, and detect communication errors, which provides high reliability. The AS5047D-ATSM is also able to detect and monitor the speed at which the rotor is rotating, allowing it to be used as a speedometer. The AS5047D-ATSM is a great option for robotic applications, where precise and reliable speed measurements are required.

In summary, AS5047D-ATSM is an encoder which is capable of measuring angular position, speed and rotational direction. It has a wide application, ranging from automotive industries to robotic applications, offering great accuracy and reliability. This encoder is also programmable, which provides great convenience and makes it easy to configure and use. The AS5047D-ATSM is an ideal option for applications which require precision and accuracy in angle measurements and speed measurements.
