直流ファンモ-タの制御装置
Document Type and Number:
Japanese Patent JP4168517
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a controller of a DC fan motor for reducing consumption at stoppage of a DC fan motor. SOLUTION: A controller includes a DC fan motor having desired revolutions by switching a motor drive DC voltage applied to a motor winding 6, a switching circuit 8 for switching the drive DC voltage for the DC motor, a control circuit 9 for controlling the switching circuit 8, a control power supply circuit 1 for operating the control circuit 9, a third smoothing circuit 2e for smoothing the voltage in the control power supply circuit 1, and a first voltage stabilizer 11 for making the output voltage stable from the third smoothing circuit 2e. In addition, a DC fan motor control power feeding means 17 for feeding control power to the DC fan motor control circuit 5 is provided between the third smoothing circuit 2e and the first constant-voltage circuit 11.
