Product Description:
The M-405-C-A1-E1 is a brushless servo motor produced by Kollmorgen. It belongs to the M Goldline Servo Motors series. Designed for closed-loop motion, it provides direct drive for positioning tables, pick-and-place heads, and packaging axes within automated cells, where precise velocity and torque control support repeatable throughput. Its brushless construction also suits applications with frequent acceleration, deceleration, and reversing cycles. This makes it suitable for compact machine axes that need repeatable starts and stops throughout long production runs.
At a winding temperature of 40 °C, the motor delivers a continuous output of 13.1 N·m. It reaches 5.4 kW at a rated speed of 5000 rpm, giving the servo system a high-speed operating range for dynamic motion. Continuous operation draws 19.8 A RMS, and rapid indexing is supported by a peak current of 55.9 A RMS. The phase inductance is 8.4 mH, which influences current rise time and helps smooth inverter ripple. A torque constant of 0.66 N·m/A RMS links commanded current to shaft torque, while the metric mounting interface supports straightforward integration with ISO gearheads. Screw-thread connectors without plugs are used for power and feedback connections, and an adapter plate is included so an external encoder can be installed when position feedback is required.
Transient loads are handled by a stall torque of 35.3 N·m. The regenerative voltage constant is 40.2 V RMS/krpm, which is useful when evaluating returned energy during deceleration. The winding resistance is 0.34 ohms, and the rotor inertia of 44.6 × 10⁻⁴ kg·m² balances responsive acceleration with stable motion under changing loads. That value also influences heating during sustained operation. Sealing to IP65 blocks dust and low-pressure water jets from reaching internal components. A rear shaft extension is present for auxiliary encoders or brakes, and the connector arrangement works with the encoder-ready adapter plate for added feedback hardware.
