Hall Sensors: 60 vs 120degrees

120deg Hall Effect Sensors
The following diagram shows 120-degree hall-effect sensors. Notice that there is electrically 120 degrees between hall transitions.



60deg Hall Effect Sensors
The following diagram shows 60-degree hall-effect sensors. Notice the Hall 3 signal is inverted (compared to 120-degree hall3) This changes the number of electrical degrees between the rising edge of the hall states.



All of the hall motors Compumotor uses are 120degrees. If we use an inverter on Hall 3 we can change a 60degrees hall state to 120degrees and vise versa.
