Functional Features​

High continuous torque relative to 57 mm frame size.

Low cogging for smooth low-speed motion.

Resolver or encoder feedback for position and speed control.

Optional holding brake for vertical or retained-load axes.

Rugged IP65 housing for industrial environments.

Application Scenarios​

Conveyors, material handling, robotic joints, index tables, CNC auxiliary axes, packaging machines and moderate-torque positioning systems.

Performance Parameters​

3 Nm continuous at 3000 rpm with 9 Nm peak for acceleration.

Fast current response governed by winding inductance and drive bandwidth.

Thermal time constant approximately 20 minutes winding, 45 minutes housing.

Material And Structure​

Cast-aluminum IP65 housing.

Neodymium-iron-boron rotor magnets.

Precision bearings, keyed shaft and resolver/encoder compartment.

Terminal or connector power and feedback interface according to suffix.

Working Principle​

Three-phase sinusoidal current creates a rotating stator field. The permanent-magnet rotor follows the field. Resolver or encoder feedback provides position/speed data to the servo amplifier, which adjusts current to maintain the commanded trajectory.

Installation Requirements​

Mount on IEC or Kollmorgen 57 mm square flange.

Align keyed shaft with coupling and avoid excessive shaft loads.

Separate shielded power cables and shielded resolver/encoder twisted pairs.

Connect thermal sensor to drive protection input where fitted.

Supply 24 V DC brake release voltage only when brake option is installed.

Usage Precautions​

Operate within 0 to 40 °C ambient unless formally derated.

Do not exceed 150 N radial and 90 N axial shaft loads.

Size servo amplifier for 9 Nm peak without sustained overheating.

Ensure brake is released before motion; loss of brake voltage re-engages holding brake.
