iCARe® Speed

Description

Properties

The iCARe® Speed product family comes with guaranted losses at 400Hz and indicative maximum values at 700Hz. These values are representative of the steel’s behaviour at high frequencies.

Advantages

The Speed grades provide an excellent compromise between mechanical properties and losses.

Applications

Speed has been developed for very high speed rotors. This enables manufacturers to make more compact machines for a given mechanical output.

Recommendations

Speed grades can be used immediately after lamination punching. The effect of punching can be eliminated if a stress relief annealing is applied. This optimises the performance of the Speed grades in applications with fine teeth. It can also provide substantial performance improvements in the lower frequency range. To achieve these effects, a C5 type coating is advised.

Speed stacks can be produced using any existing assembly technique such as interlocking or welding.
