Functional Description
1.
Basic Operation
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.
Basic Operation Flow
*: A refresh operation is not performed.
<Rotation Speed for Drive-Signal Switching>
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)
Tu
= 6 Hz, N = Number of motor poles
Example) When using a 8-pole motor
R
= 60 × 6 × 2/8 = 90 (rpm)
Thus,
Sensorless square-wave drive: From start to 90 rpm
Sensorless sine-wave drive: 90 rpm

Drive Control with Operation Instruction Input (VSP)
Control the commutation output with VSP input voltage.
(1)
Voltage instruction input: 0 V
≤ VSP < 2.1 V
Disables (Low) the commutation output
(2)
Voltage instruction input: 2.1 V
≤ VSP ≤ 8.5 V
Controls the motor drive.
(3)
Voltage instruction input: 9.5 V
≤ VSP ≤ 11 V (Test mode)
Automatic lead-angle correction feature is disabled.
A mode switching occurs when VSP = 9.0 V (typ.).
