IntelliFlo ® VS Drive Assembly and Control Panel
The IntelliFlo drive assembly consists of an operator control panel and the system electronics that
drive the motor. The drive microprocessor controls the motor by changing the frequency of the
current it receives together with changing the voltage to control the rotational speed.
IntelliFlo ® VS Motor Assembly
The IntelliFlo ® three-phase six-pole motor operates at 3400 RPM (at 92% efficiency) and 1000 RPM
(at 90%). The motor assembly is continually cooled by an external fan. Dual seals on the motor shaft
and at the fan assembly seal the entire motor from any moisture from entering the motor assembly.
For added protection, a slinger located in front of the main shaft seal assists in slinging water away
from the shaft opening in the flange.
