hello everyone
A few manufactures have changed from the conventional a/c case evaparator fan motors.
Ive found that the prefered motor is a fixed blade 230v DC motor ,
The advantages are :
1)2 speed (night operation).
2)programming interface for setting of motor speeds (off line).
3)protection class 2 no grounding neccesary.
4)plug in connection (included).
5)high life cycle >40.000 hours due to ball bearings.
6)good acoustics due to anti vibration mount .
7)electronics protected against moisture and cleansing agents.
8)reduced power consumption.
I thought this may be of some interest to the readers of this forum.
regards mark
