iCARe® Torque

Properties

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

Advantages

Torque grades assist flux generation, allowing the motor to develop more mechanical output. If mechanical output is not an issue, permanent magnet or copper winding can be reduced to save on costs.

Applications

Torque grades are suitable for machines which need high torque at low speeds. They provide the fast acceleration required by hybrid and electric vehicles.

Recommendations for use

Torque 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 Torque 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.

Torque stacks can be produced using existing assembly techniques such as interlocking or welding.
