Product Details

KEB DL4 servo motors are dynamic 8-pole motors as standard with speeds from 1000 rpm to 3,000 rpm (varies by model). They are available in 400V.

For maximum flexibility, KEB servo motors are provided with rotatable connectors.

KEB servo motors utilize neodymium permanent magnets to provide exceptional torque density. Units are rated for maximum torques of at least 300% of the rated continuous stall current.

KEB servos offer up to 11Nm nominal torque and 520Nm peak torque.

Motor coating – Varnishing RAL 9005.
