Description

HKW-series frameless spindle motor kits are designed for direct integration within the machine mechanics and offer high torque at slow speed and very high speed at constant power. With 400VAC windings, power ratings to 230kW and speeds to 50000 min-1
Product Overview
HKW motors are high performance permanent magnet synchronous servo motors for spindle applications up to 230 kW. Delivered as separate components to be integrated into the mechanical structure of the machine, HKW motors benefit from the use of field weakening, in order to achieve both high torque at slow speed, and very high maximum speed at constant power.

Applications:
• Tooling Machines
