MTC704B1-F1A1 by Kollmorgen

The Kollmorgen MTC704B1-F1A1 servo motor delivers advanced motion control performance in the MTC Servo Motors series, combining high power density with precise torque management for demanding industrial automation tasks. With a peak torque of 62.2 N·m and a continuous torque of 23.5 N·m, this model addresses both dynamic acceleration and sustained load requirements. The motor generates 5.6 HP (4.2 kW) at a rated speed of 2500 / 3000 rpm, enabling rapid positioning and high throughput. Weighing just 24.2 kg, the robust yet compact design simplifies mechanical integration into machine tools, robots, and process control systems.

Rated electrical performance is characterized by a continuous line current of 10.7 A (arms) and a peak line current of 36.7 A (arms), supporting line-to-line voltages up to 400/480 Vrms. The eight-pole rotor design (Number Of Poles: 8) balances smooth torque production with reduced cogging for exceptional low-speed stability. At rated conditions, the motor maintains a thermal time constant of 45 minutes, facilitating predictable temperature rise under continuous operation. The rotor inertia of 0.013 kg·m² (0.0096 lb·ft·s²) enables rapid speed changes and minimizes overshoot during step responses.

Operational features include a static friction torque of 0.237 N·m that ensures minimal holding resistance when stationary, while the low rotor inertia accelerates load transitions with minimal delay. The motor’s speed range from 0 to 3000 rpm covers both fine positioning and high-speed traverse profiles in a single drive solution. Thanks to the robust construction and efficient thermal characteristics, the MTC704B1-F1A1 sustains continuous operation at full load without performance degradation. Vibration and noise levels are managed through precision balancing and high-quality bearings, resulting in reliable duty cycles in harsh industrial environments.

System integration is streamlined through compatibility with Kollmorgen AKD and AKM drive families, supporting fieldbus and EtherCAT communications for synchronized multi-axis control. The motor’s wide voltage tolerance and standardized flange dimensions facilitate retrofits and new installations in CNC machines, packaging lines, automated assembly cells, and robotics platforms. Designed for engineers seeking a high-torque, high-speed solution, the MTC704B1-F1A1 delivers both exceptional dynamic response and robustness for modern industrial automation applications.
