Hall Effect Speed Sensor Working Principle

Hall effect sensors are used for proximity switching positioning speed detection and current sensing applications.

Hall effect speed sensor working principle.

Hall effect sensor operating principle. Door activated led lighting using hall effect sensors. The working principle of hall effect sensor is based on hall effect which states that when a current carrying conductor is placed into a magnetic field a voltage will be generated perpendicular to both the current and the field. A hall effect sensor may primarily comprise of a temperature regulated hall plate along with a comparator stage an active compensation network and an open drain output transistor.

Hall effect sensors consist basically of a thin piece of rectangular p type semiconductor material such as gallium arsenide gaas indium antimonide insb or indium arsenide inas passing a continuous current through itself. Jeremy nash explains what a hall effect sensor does in a brushless motor and how to replace the sensor when it fails. On a thin strip of a conductor electrons flow in a straight line when electricity is applied. It actually consists of a current carrying metal strip when this current carrying metal strip is placed inside any transverse magnetic field then emf is developed across the edges of this current carrying metal strip.

A wheel containing two magnets passing by a hall effect sensor. The principle of hall voltage is used as a working principle of the hall effect sensor. Hall effect sensors are used to detect the presence and strength of a magnetic field. In its simplest form the sensor operates as an analog transducer directly returning a voltage.

A hall effect sensor switch is constructed in form of a small integrated. One speed sensor is called the input shaft speed sensor and the other is the output shaft speed sensor. The clutch connects the input shaft to the engine. When this charged conductor comes in contact with the magnetic field which is in a perpendicular direction to the motion of electrons the electrons get deflected.

When the device is placed within a magnetic field the magnetic flux lines exert a force on the semiconductor material which deflects the charge carriers electrons and. Figure 1 hall effect sensor. The function of the input shaft speed sensor is to keep track of the transmission s input shaft speed. Hall effect sensor operating principles and specification unlike inductive sensors the output signal from a hall effect sensor is not effected by the rate of change of the magnetic field.

Electric bike hub motor how to replace a hall effect sensor. Unlike inductive sensors the output signal from a hall effect sensor is not affected by the rate of change of the magnetic field. To make the ic sense a magnetic field it becomes important that the magnetic lines of flux strike perpendicular to its surface and is not beyond 5mm from the ic. The produced output voltage typically is in the range of mv and is additionally amplified by integrated electronics fitted inside of the sensor housing.

These two sensors work together to relay information back to the engine control unit. Working principle of hall effect sensors.
