Application Information
1. SYSTEM BLOCK DIAGRAM
The figure 1 shows concept of soft switching for 3-phase output with a hall sensor.
Figure 1.
Peak detector
Generates clock pulses at the peak points of the hall signal.
Stair wave generator
Generates 3 stair wave signals 120 degree apart from the clock pulses.
3-phase motor drive circuit
Controls output currents to operate 3-phase motor using the vol
tage difference between the 3 stair wave signals and FG hall signal.
2. STRUCTURE OF BLDC MOTOR
Consists of main and sub magnets. For every main magnet there are 3 submagnets as shown in Fig 2.
Sub-magnet takes hall signal and goes through 6 gradual filtering steps purifying in order to operate 3-phase motor with one
hall sensor.
