Optimised design for asynchronous IE3 engines

692

The design of its proven IE3 asynchronous engines has been optimized by NORD. The maintenance model refers to various specifics that further improve the function, installation and operation of electric motors.

The facelift of the NORD DRIVESYSTEMS IE3 asynchronous motors does not require improvements in electrical details and exterior measurements. For NORD IE3 generators, they can be used conveniently without alteration in any current application.The optimised cooling fin shape, an assembly-optimised fan and a new modern fan cowl enable a better heat dissipation and assembly.

The fan cowl can be simply assembled in case a motor mounted frequency inverter is used. The new cooling fins design enables an unhindered airflow around the terminal box. The revised terminal box is without sharp edges and corners and has reinforced feet for a better motor stability. Another important detail is the optimised incremental encoder mounting.

Due to the fan cowl, the encoder is fully shock-resistant and not within the airflow, which further improves the cooling power. Because of a plug-on tube, retrofit installation is also feasible.
