Product Description

1. Product Description 
Modular induction motors, type AMI
High reliability and availability
AMI engineered modular induction motors provide reliability and availability in the toughest and most demanding applications.
Engineered modular induction motors are tailor- made to meet the needs of each customer and each application. Built from the motor industry's most successful modular platform, they match a broad variety of demanding application requirements while having the flexibility to be adapted to highly specific configurations.
Modular induction motors comply with all relevant international standards. Versions are available for both direct-on-line (DOL) and variable speed drive (VSD) operation.
AMI modular induction motors have a welded steel frame. They are available with the following cooling methods and protection types as standard: IC01 / IP24W, IC611 / IP55 and IC81W / IP55. The standard shaft heights are 400 to 630 mm. The motors can be mounted horizontally or vertically.
For AMI motors this catalog shows the technical data at 50 Hz only, but these motors are operating at both 50 Hz and 60 Hz, with synchronous speed from 500 to 3600 rpm.
Output powers for AMI motors covered in this catalogue are up to 8,000 kW, while the complete range goes up to 23,000 kW.

2. Mounting arrangements
Standard mounting arrangements for AMI motors. Other mountings available on request.

                                                                                                                            (free shaft end facing downwards)

3. Enclosure and cooling
 

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.
 

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.

4. Packaging
