The principle of Hall switch in servo motor: Hall switch plays a steering role in servo motor. There are multiple magnets inside the motor, and they are placed alternately. Before the control signal is sent, the rotor is in a stationary state. When the magnet senses the Hall element, the Hall outputs a high-low level signal conversion, and the speed starts accordingly. This can accurately control the direction of the motor and is widely used by major motor manufacturers.
Usually, bipolar latch Hall switch elements are used inside servo motors. This is related to the alternating arrangement of magnets inside the motor. The signal sent by the motor can be more accurately controlled. In addition, bipolar latch Hall switches are widely used and have a long market application cycle, which has been widely verified.
Recommended model: Bipolar latch high-voltage and high-temperature Hall switch HS41F
HS41F high-temperature bipolar latch Hall effect position sensor is a magnetic sensing circuit composed of an internal voltage regulator unit, a Hall voltage generator, a differential amplifier, a temperature compensation unit, a Schmitt trigger and an open collector output stage. Its input is magnetic induction intensity and its output is a digital voltage signal.
It is a dual-pole magnetic sensing circuit suitable for working under rectangular or cylindrical magnets.
The operating temperature range can be from -40℃ to 150℃, the power supply voltage range is from 3.8V to 30V, and the load current capacity can reach up to 40mA.
The package form is SIP3L (TO92S).
