The TB6582FG is a sensorless 3-phase hall motor controller driven by the sine wave. It provides a
sensorless square-wave drive with zero-cross detection of the induced voltage, without using position
sensors, such as a Hall-effect element. It also achieves a sensorless sine-wave drive by calculating the
induced voltage waveform using the induced voltage equation.
At startup, the motor operates in sensorless square-wave mode. The operation mode switches to sensorless
sine-wave mode when the rotation speed reaches 90 rpm in the case of an 8-pole motor.

*: A refresh operation is not performed.
Rotation speed is converted from the phase-current frequency Tu. When Tu reaches 6 Hz, the drive signal
is switched between square wave and sine wave.
Rotation speed: R (rpm) = 60 × Tu × (2/N)
