... TOSHIBA CMOS Integrated Circuit Silicon Monolithic PWM Sensorless Controller for 3-Phase Full-Wave BLDC Motors The TB6575FNG provides sensorless commutation and PWM current control for 3-phase full-wave BLDC motors. It controls rotation speed by changing a PWM duty cycle by analog voltage. Features • 3-phase full-wave sensorless drive • ...

... DC excitation mode and then the rotation is started in forced commutation mode. An external capacitor sets the times that the TB6575FNG stays in DC excitation and forced commutation modes. Those times vary depending on the motor type and motor loading. Thus, they must be adjusted experimentally ...

... SC Signal Delay in Rotational Speed Control (V The V input is used to control the motor speed; the TB6575FNG allows the motor to start, stop and SP change the speed according to the voltage at V the voltage applied to the SC input. The voltage at the SC input equals the charging voltage of the capacitor C1, which depends on its charging and discharging times ...

... Motor position detection error A position detection is synchronized with the PWM signal generated in the IC. Thus, a position detection error relative to the PWM signal frequency may occur. Keep this in mind especially when the TB6575FNG is used for a high-speed motor. A detection is performed on the falling edge of the PWM signal. An error is recognized when the pin voltage exceeds the reference voltage. Detection error time < ...

... OUT_WN 10. Overlap commutation When SEL_LAP = high, the TB6575FNG is configured to allow for 120° commutation. When SEL_LAP = low configured to allow for overlap commutation. In overlap commutation, there is an overlap period during which both the outgoing transistor and incoming transistor are conducting (as shown in the shaded areas) ...
