Product Description
Modular
induction motors type AMI are engineered for high reliability and
availability in the toughest and most demanding applications. Built from
the motor industry's most successful modular platform, they are tailor
made to meet the needs of each customer and each application, matching a
broad variety of demanding requirements while offering the flexibility
to be adapted to highly specific configurations.
AMI
modular induction motors comply with all relevant international
standards. Versions are available for both direct on line (DOL) and
variable speed drive (VSD) operation. The motors feature a welded steel
frame and are available with the following cooling methods and
protection types as standard: IC01 / IP24W, IC611 / IP55, and IC81W /
IP55. Standard shaft heights range from 400 to 630 mm, and the motors
can be mounted horizontally or vertically.
While
this catalog shows technical data at 50 Hz only, these motors operate
at both 50 Hz and 60 Hz with synchronous speeds from 500 to 3600 rpm.
Output powers covered in this catalogue are up to 8000 kW, while the
complete range extends up to 23000 kW.
Mounting Arrangements
Standard mounting arrangements for AMI motors are as follows. Other mountings are available on request.
-
Code I: IMB3 / Code II: IM1001 — Horizontal foot mounted
-
Code I: IMV1 / Code II: IM4011 — Vertical flange mounted (free shaft end facing downwards)
Enclosure and Cooling
IC01 / IP24
This
weather protected motor has a shaft mounted cooling fan inside the
housing. The design 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 heavier particles to settle. 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.
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 with Asymmetric Inside Air Circulation
A variant of the IC01 cooling method featuring asymmetric internal air circulation for optimized thermal performance.
Packaging
Standard
seaworthy package for export. Plywood package or wooden fumigation
package. Suitable for long distance transportation by sea or land.
Warranty Period
Standard
warranty: 12 months after commissioning, or 18 months after delivery,
whichever comes first. Extended warranty periods are available upon
request. Please contact us for more details.
