Product Description:

The M-207-C-23 is a brushless servo motor produced by Kollmorgen within the M Goldline Servo Motors series. It is intended for closed-loop industrial automation where precise speed and position control are required, and it interfaces with matched Kollmorgen servo drives to move packaging, converting, and assembly axes. The housing measures 92 mm in diameter, extends 373.2 mm in length, and weighs 9.5 kg, which helps with machine layout and load calculations.

The electromagnetic profile is anchored by a back-electromotive-force constant of 37.7 Vrms/kRPM, which helps the drive calculate voltage demand at a target speed. Under steady thermal equilibrium, the motor delivers a continuous stall current of 10 Arms, yielding a continuous stall torque of 6.44 N-m at the shaft. These steady-state limits are linked to the torque constant of 0.624 N-m/Arms, which translates phase current into usable torque for position loops. Winding inductance is 11 mH, shaping current ripple and influencing the bandwidth that can be commanded without excessive drive switching losses. Complementary parameters include 0.82 Ω of DC resistance, which contributes to copper losses, and a thermal resistance of 0.62 °C/W; both values factor into drive sizing and cabinet ventilation.

Dynamic events are handled by a peak stall torque of 19.5 N-m that can be applied when rapid acceleration or disturbance rejection is necessary, supported by a peak stall current of 33 Arms. The rotor inertia of 0.0018 kg-m² offers a balance between quick speed changes and stability when following high-resolution command profiles. Heat soak during intermittent overload is moderated by a thermal time constant of 21 min, allowing brief high-power cycles before the windings reach rated temperature. Additional mechanical data include a 14 mm shaft diameter, a 30 mm shaft extension for coupling design, and a motor length-to-diameter ratio that maintains torsional stiffness while keeping overhung load within common bearing limits.
