Product Description:

The M-207-B-23-B3 is a brushless servo motor built by Kollmorgen within the M Goldline Servo Motors series. Designed for closed-loop motion axes, the unit converts drive current into controlled rotary torque so automated packaging, machining, and material-handling equipment can position payloads with repeatable accuracy. Its internal permanent magnets and feedback interface let it integrate with Kollmorgen servo amplifiers for responsive speed and torque regulation in industrial automation lines.

Under continuous duty at 40 °C, the motor delivers a steady 6.24 N-m of shaft torque while drawing 5.8 A RMS, a level that matches its torque sensitivity of 1.08 N-m per amp and is resisted by a 2.32-ohm winding impedance. When higher acceleration is required, the drive may command the 19.9 N-m peak torque for short intervals; this draws up to 19.5 A RMS from the inverter, so conductors and fusing must be sized accordingly. Nominal operation occurs at 2800 RPM, and at this speed the motor outputs 1.80 kW of mechanical power, provided the bus supplies no more than the 250 V RMS maximum line voltage. These values keep the three-phase stator within its thermal range while maintaining linear torque production across the operating speed range.

The drive must also account for the motor’s electrical dynamics. A back electromotive force of 65.1 V RMS/kRPM establishes the voltage seen by the controller as speed rises, while the 32 mH phase inductance stores energy that filters current ripple and shapes current-loop bandwidth. Mechanical response is governed by the modest 0.0018 kg-m² rotor inertia, allowing rapid speed changes without excessive regenerative energy. For vertical axes, an integral brake supplies 6.0 N-m of holding torque; it engages at 24 V DC and draws only 1.27 A to secure the load when power is removed. These values affect stopping behavior, regenerative energy, and servo loop tuning during demanding motion profiles.
