Document Type and Number:
Japanese Patent JP2012016274
Kind Code:
A
Abstract:
To provide a motor drive controller capable of protecting itself from an electromotive force of a motor generated by the rotation of a fan rotated by external wind, increasing the number of turns of a motor coil, and suppressing a motor current.
A motor drive controller, driving a motor 7 for rotating a fan, includes: an inverter circuit 5 that converts a DC voltage to AC voltage and applies it to the motor 7, and control means that controls the inverter circuit 5 and operation of the motor 7. The inverter circuit 5 has a switching element for both terminals of each phase of the coil of the motor 7. The control means controls a switch pattern of the switching element to control operation of the motor 7.
