What is the role of the hall sensor in a DC motor. A hall effect sensor is a sensor that varies its output based on the presence or absence of a magnetic field. When the rotor spins away, magnet #1 stops affecting the Hall IC. Either way, if the motor has 8 or 9 wires/pins coming out of it on the cable, then it is a hall effect motor. Stepper motors allow precise control of their shaft position, using microstepping you can control this to a fraction of a degree. A Hall-effect sensor (or simply Hall sensor) is a device to measure the magnitude of a magnetic field. Magnetic sensors convert magnetic or magnetically encoded information into electrical signals for processing by electronic circuits, and in the Sensors and Transducers tutorials we looked at inductive proximity sensors and the LDVT as well as solenoid and relay output actuators. This is the job of the Hall effect sensors—to monitor the rotor’s position. Hall effect sensors measure the strength of a nearby magnetic field. In this motor each hall effect sensor has 4 pins: VCC (H+), GND (H-) and two outputs (some sensors come with 3 pins: VCC, GND and output). hall sensor. The Hall sensor is designed to flow 20 milliamps or less. Today we will look at how to use a hall effect sensor with Arduino. The transistor opens, and allows a bigger collector current to flow through the electromagnet. Hall-effect devices are used as proximity sensors and for positioning, speed, and current detection. To electric motors with only one pair of magnetic poles, the space between the electrodes is 180°. Note which wire goes to which leg of the hall sensor as this is important when installing the new sensor.
