Brushless torque motor QMT series

680Valuminiumhollow-shaft

Overview
The QMT torque motor series is designed for the machine-tooling market, combining mechanical compatibility with a balance of power and precision to improve motion capabilities and the performance of existing machine designs.

Series and subseries
The QMT series comprises two subseries: the LA series and the higher-rotor HA series. The HA subseries features a larger rotor, delivering higher performance and greater power density compared with the LA variants.

Applications

• Cutting
• Grinding
• Metrology
• Rotary indexing tables

Key features and benefits

• Outstanding stall torque in a compact design suitable for heavy-duty tasks in limited spaces
• Direct integration into the machine structure (no additional gearbox or drive train required)
• Large open inner diameter enabling wire and cable feedthrough
• No contact between rotor and stator → no mechanical wear
• Brushless torque motor design removes the need for gearboxes, belts and speed reducers
• Aluminium housing with integrated water-cooling channels as standard to increase maximum performance
• Housing includes bolt holes to simplify mechanical installation
