Servomotors offer stall torque of 85.0, 120.0 Nm

Heidenhain Corp. has introduced the QSY 260B and QSY 260C EcoDyn series of servomotors with stall torque of 85.0 and 120.0 Nm, respectively. The motors provide low torque ripple for high-speed stability and positioning accuracy, the company reports.

A high rotor moment of inertia provides for high maximum acceleration and high load inertia. Common applications for these motor types include large boring mills and other heavy-load machining.

Maximum permissible rated speed is 3,000 min–1. The motors come equipped with incremental or absolute rotary encoders.
