Halls Order
Each hall signal is in phase with one of the three phase-phase voltages from the
motor windings. Hall order number defines which hall sensor matches which phase-
phase voltage. Motor phases are usually called R-S-T or U-V-W or A-B-C. Phase-
Phase voltages are called Vrs, Vst, Vtr. Halls are usually called HALL-A, HALL-B,
HALL-C or just Halls 1, 2, 3. A motor’s phase diagram is supplied by motor vendor
and usually can be found in the motor datasheet or by making a request to the motor
manufacturer. A sample phase diagram is shown below.
The Halls Order is obtained as follows:
1. Look at the “R” Output Voltage. Determine which Hall Voltage is lined up
with (or in phase with) this voltage. We can determine which Hall Voltage is
in phase with the R Output Voltage by drawing vertical lines at those points
where it crosses the horizontal line (zero). The dashed lines at the zero
crossings (above) indicate that Hall B output is lined up with (and in phase
with) the R Output Voltage.
2. Look at the “S” Output Voltage. Determine which Hall Voltage is in phase
with this Voltage. As can be seen, Hall C output is in phase with the S
Output Voltage.
3. Look at the “T” Output Voltage. Determine which Hall Voltage is in phase
with this Voltage. As can be seen, Hall A output is in phase with the T Output
Voltage.
Note
If hall sensors are in phase with corresponding phase voltage but
inverted 180 degrees (hall sensor waveform edge aligns with phase-
phase voltage waveform but positive hall sensor cycle matches
negative phase-phase waveform or visa-versa), you must check
“Inverted” check box.
4. The phases that correspond to the Vrs Vst Vtr voltages are Hall B then Hall
C then Hall A or halls number 2 then 3 then 1. Looking at Table 9 we find
that 2-3-1 sequence is Halls Order number 3. We would enter 3 for the Halls
Order field in motor dialog.
