Product Description:

The M-105-A-34 is a brushless servo motor produced by Kollmorgen within the M Goldline Servo Motors series. This compact rotary unit is intended for closed-loop industrial drives where speed and torque must be managed dynamically through a motion controller. By integrating a frameless resolver for real-time position data, the motor supports precise indexing, coordinated multi-axis moves, and repeatable cycle times in automated assembly, packaging, and test equipment. Because the resolver supplies continuous position feedback, the paired drive can track rotor motion smoothly across changing speeds and maintain synchronized movement with neighboring axes.

Under continuous load conditions, the motor maintains a 1.55 N-m shaft output without overheating. To support that effort, it requires a steady supply of 3.00 A RMS line current from the drive. At the rated mechanical speed of 5600 RPM, the windings generate a back electromotive force of 31 VRMS/kRPM, which is the voltage the amplifier must overcome during acceleration. The winding inductance is 28.1 mH, and this affects current ripple as well as current-loop response. These electrical values help the motor hold steady velocity under constant process loads and support smooth torque delivery during long production runs.

For short bursts, the rotor can generate 4.38 N-m of torque while the drive supplies up to 9.0 A RMS. The electromechanical design yields 0.90 kW of rated power, balancing output and inertia for medium-speed stations. A torque constant of 0.51 N-m/A RMS links commanded current to produced torque, which helps the drive respond predictably during rapid speed changes. Bayonet connectors with mating plugs allow quick cable attachment, and the metric face mount supports integration with compatible gearheads. The motor also has no front shaft seal, which reduces friction when it is installed in clean, protected enclosures. Its line resistance is 5.30 Ω, completing the electrical profile.
