Product Description:
The MT308A1-E1C1 is a permanent-magnet servo unit manufactured by Kollmorgen within the MTC Servo Motors series. It is intended for tightly regulated motion axes where repeatable torque and speed are critical to product quality and throughput. When integrated with a matched drive, the motor provides precise position control for packaging equipment, pick-and-place heads, and light machine-tool feeds in industrial automation.
At 25 °C, the motor delivers a continuous stall torque of 5.10 N·m while drawing a continuous line current of 2.58 A RMS. When the winding temperature rises to 40 °C, the permissible stall torque falls to 4.79 N·m, demonstrating the effect of temperature on torque output. Electrical characteristics include a line-to-line inductance of 80 mH and a copper resistance of 8.45 Ω, which affect the electrical time constant and steady-state losses. The back electromotive force is 114.8 V RMS per krpm, and the windings are designed for a 250 V RMS supply. Under rated operating conditions, the shaft turns at 1500 rpm. For rapid load changes, the drive may impose a peak line current of 12.2 A RMS, enabling short bursts of additional torque. The torque sensitivity is 1.898 N·m per ampere, supporting accurate current-mode control. These electrical properties allow the matched drive to regulate winding current in response to changing speed and load demands.
The motor supports peak torque events up to 18.76 N·m. Combined with a rotor inertia of 0.0001749 kg·m², this torque yields a theoretical acceleration ceiling of 107,278 rad/s² for fast indexing moves. Continuous mechanical output reaches 0.67 kW, delivering useful power from a 5.1 kg frame without an integral brake. A thermal time constant of 33 min indicates how quickly the housing approaches thermal equilibrium, which helps with the selection of cooling airflow and dwell times. The absence of an integral brake means that an external holding device or drive-applied torque is required when a stationary load must remain secured. Its thermal behavior must be considered when repetitive operating cycles combine rapid acceleration, sustained torque, and stationary holding periods.
