Product Description:

The M.1300.3487 is a brushless servo motor produced by Kollmorgen as part of the NSM Brushless Servo Motors series. This model is intended for closed-loop industrial axes where compact direct-drive torque and precise velocity control are required. By coupling to a suitable drive, the unit converts three-phase stator power into controlled rotor motion, enabling positioning tasks in packaging, electronics assembly, and material transfer lines.

Under continuous load, the motor delivers 1.8 Nm of shaft torque, and it can maintain this output while spinning at a sustained speed of 4,500 rpm. For short duty cycles, the electromagnetic stack withstands overloads up to 5.7 Nm, supplying extra acceleration force during indexing moves. The permanent-magnet design has a torque constant of 0.41 Nm/A, so the drive must supply approximately 4.4 A to reach the continuous torque rating. The stator windings are configured for a 230 V line-to-line rating, have a resistance of 2.8 Ω, and present an inductance of 11.0 mH. These electrical values affect current ripple and the required pulse-width modulation switching frequency. Heat generated in the copper and iron is transferred through the housing with a thermal resistance of 1.1 °C/W, helping keep the winding temperature within operating limits when ambient cooling air is available.

A spring-applied brake rated at 24 VDC holds the shaft during power loss or emergency-stop events. Position feedback is provided by an optical encoder with a 2,000-line resolution; its electronics require 5 VDC and draw up to 300 mA, permitting direct connection to most motion controllers. Dynamic performance benefits from a low rotor inertia of 0.00024 kg·m², allowing rapid reversals with minimal drive effort. The cast housing and laminated core bring the total mass to 4.7 kg, which aids heat dissipation while keeping installation manageable.
