IC01
Standard combinations for AMI motors:
IC01 / IP24
This weather protected motor has a shaft
mounted cooling fan inside the housing.
The design of the motor reduces the ingress
of rain, snow and airborne particles into the
electrical parts. On the air intake path this is
achieved by ensuring that the average velocity
does not exceed 3 m/s, allowing any heavier
particles to settle. The design of the air intake
path includes three acute direction changes
in excess of 90 degrees to further reduce the
flow rate to the optimal level. The motor is
protected against splashing water from any
direction.
IC611 / IP55
This design has an air-to-air heat exchanger
mounted on the motor, which is fully enclosed.
Shaft mounted fans are fitted both inside and
outside of the casing to supply the inside and
outside cooling circuits respectively. The motor
is protected against dust and splashing water
from any direction.
IC81W / IP55
This fully enclosed motor is fitted with an
air-to-water heat exchanger. A shaft mounted fan
is fitted inside the casing to supply the internal
cooling circuit. The motor is protected against
dust and splashing water from any direction.
The terminal boxes have a protection rating of
at least IP55.
IC31 / IP55
This version is fitted with inlet and outlet pipes
to use remote cooling air. Essentially this is
the AMI motor frame without an upper cover.
The motor is protected against dust and
splashing water from any direction.
IC01
IC01 with asymmetric inside air circulation.
