Document Type and Number:
Japanese Patent JP2002349442
Kind Code:
A
Abstract:
To overcome defects in appearance of an automatic water feed device.
In this automatic feed device wherein a magnetic sensor 181 detects a magnetic pole position of a motor rotor of a DC brushless motor 18 for driving a pump 15 and transmits a detected magnetic pole position as magnetic pole position detection information via a magnetic pole position detecting code 21 to a CPU 191 of a control panel 19 for controlling the pump, and the CPU 191 variably drives the pump on the basis of the magnetic pole position detection information via a cable 22, the magnetic pole position detecting code and a three phase output cable are housed in one cable to connect the pump and the control panel.
