Document Type and Number:
Japanese Patent JP6815470
Kind Code:
B2
Abstract:
To obtain a motor driver capable of realizing air volume control corresponding to single-phase instantaneous power pulsation, when realizing air volume control for a single-phase PM motor.SOLUTION: A motor driver 100 for driving a motor blower including a single-phase PM motor 3 includes a single-phase inverter 2 for rotating the rotor of the single-phase PM motor 3 by applying an AC voltage to the single-phase PM motor 3, a motor current detector 5 outputting a signal according to a motor current flowing through the single-phase PM motor 3, a DC power supply voltage detector 6 for detecting the voltage of a DC power supply 1 supplying power to the single-phase inverter 2 and an inverter control section 4 receiving the motor current and outputting a drive signal to switching elements 211-214 of the single-phase inverter 2, where the single-phase inverter 2 increases and decreases effective power or wattless power supplied to the single-phase PM motor 3, and changes the number of revolution of the single-phase PM motor 3 by increasing and decreasing effective power or wattless power.SELECTED DRAWING: Figure 1
