Blower and electric device equipped with the same |
| abstract |
An object of the present invention is to provide a blower device that realizes highly accurate airflow-static pressure characteristics with very little change in airflow even when static pressure such as pressure loss changes without using a DC power supply using a chopper circuit. It is said. A current supplied to an inverter circuit is linearly changed with respect to a reference current value in accordance with an equivalent voltage detected by an equivalent voltage detection means by a correlation instruction means. Since the supply current also increases and the supply current decreases as the rotational speed decreases, the motor characteristics increase the shaft torque at which the rotational speed increases, and the blower 10 has a large air volume even if the pressure loss changes. An air volume-static pressure characteristic that does not change is obtained. [Selection] Figure 1 |
