Detailed content

Technical Specifications​
Frame size: 37.
Rated speed: 6000 rpm.
Maximum speed: approximately 7500 rpm.
Rated torque: approximately 0.5 Nm.
Peak torque: approximately 1.5 Nm.
Rated power: approximately 0.31 kW.
Brake holding torque: approximately 2 Nm where integrated holding brake is fitted.

Protection class: IP65.
Operating temperature: 0 to 40 °C.
Functional Features​
High-speed winding for rapid spindle or rotor duties.
Integrated holding brake retains load position during power loss where fitted.
High-resolution encoder feedback for accurate speed and position loops.
Low-inertia rotor for fast start-stop cycles.
Sealed industrial construction for coolants, dust and workshop environments.
Application Scenarios​
High-speed pick-and-place systems, robotic axes, packaging machines, indexing tables, light milling or grinding auxiliaries and vertical axes with brake.
Performance Parameters​
Constant high-rpm operation with low torque ripple in selected control mode.
Brake engagement on power removal, release by specified DC supply when fitted.
Encoder resolution configured according to machine accuracy requirement.
Material And Structure​
Anodized aluminum housing.
Rare-earth magnet rotor.
Hardened steel shaft.
High-speed ball bearings.
Rear brake and encoder compartment with industrial connectors.
Working Principle​
The servo amplifier generates variable-frequency three-phase current for the stator. The permanent-magnet rotor follows the rotating field. Encoder signals return position and speed to the controller. The holding brake mechanically locks the shaft when de-energized.
Installation Requirements​
Flange-mount using specified 37-frame pattern.
Couple the shaft with balanced flexible coupling.
Route power, encoder and brake cables separately with shielding.
Connect protective earth and verify brake release voltage before automatic operation.
Usage Precautions​
Do not operate above 6000 rpm rated or 7500 rpm maximum without drive confirmation.
Brake is holding, not primary stopping device, for many high-inertia loads.
Avoid sustained overload beyond peak torque and thermal limits.
Keep ambient temperature within 0 to 40 °C for rated performance.
