How Many Types of Motor Hall Sensors Are There?

[RosalieLee]

There are six types of motor Hall sensors: Brake levers, with two types of electronic brake levers: One is the Hall type, such as OH44E, which is a switch signal, and the other is a micro switch. Normally, when braking, the acceleration motor does not rotate. There is one type in the throttle: It uses a linear Hall sensor, such as OH49E, etc. If the throttle is faulty, it usually does not accelerate or directly accelerates (runaway). The motor has three Hall sensors in total: Upon opening, you will see three Hall sensors on the coil, generally switch Hall sensors, such as: OH44E unipolar switch, OH41 bipolar latch, or OH41F bipolar latch, etc. Whether to use a bipolar latch Hall sensor or a unipolar Hall sensor depends on the motor phase: the motor has a stator (fixed magnets) and a rotor (rotating coil). When the coil is energized (current passes through), it generates a magnetic field (S or N pole) that interacts with the stator, creating an attractive or repulsive force. The motor's power comes from these attractive or repulsive forces. The timing of attraction or repulsion is determined by the Hall sensor providing a signal at the right moment to change the direction of the current in the coil (changing the S or N pole of the coil).
