Document Type and Number:
Japanese Patent JP2006283691
Kind Code:
A
Abstract:
To provide a multiple blade type blower of power saving, low noise and space saving design providing high gradient curve of small air capacity change at a time of load pressure change with using a direct current brushless motor without changing shape of the multiple blade type blower and establishing rotation speed high.
This blower is provided with the direct current brushless motor as a drive means and a current value limiting means capable of arbitrarily setting a limit value of current used by the same is added on the motor. Also, a control driver for direct current brushless motor control including setting unit monitoring current value and setting current limit value is provided.
