Product Description:
The MT1506A1-R2C1 is a brushless servo motor produced by Kollmorgen within the MTC Servo Motors series. This compact rotary actuator converts drive current into controlled shaft torque for position, speed, and acceleration loops in automated machinery. Its size and operating characteristics make it suitable for pick-and-place stations, light conveyor axes, and other applications that require controlled rotary motion.
Its rated mechanical output reaches 0.67 kW, allowing the motor to provide continuous shaft power at a rated speed of 6000 rpm. Under stall conditions, the windings can sustain 1.353 N·m without exceeding thermal limits, while the drive must supply 2.89 A RMS to maintain that torque. Short bursts can elevate shaft torque to 4.62 N·m, accommodating momentary load spikes during rapid indexing. The line-to-line resistance is 5.33 Ω, and the insulation voltage is 250 V RMS. These electrical values help determine compatibility with the connected servo drive. A peak line current of 11.4 A RMS is permitted during acceleration, supporting rapid changes in shaft speed when the load remains within the motor’s operating limits. The back EMF constant and phase inductance also affect current-loop response and torque control.
The electrical back EMF constant of 28.8 V RMS/krpm relates shaft speed to generated voltage, so the controller must account for increasing back EMF as velocity rises. Current regulation is also influenced by the phase inductance of 14.9 mH, which limits the rate of current change and helps smooth torque ripple. The motor case has a thermal time constant of 24 min, allowing its temperature to change gradually during sustained operation. Adequate airflow remains necessary when the motor operates in a confined space or near other heat-producing equipment. Mechanical responsiveness benefits from low inertia and a static friction value of 0.024 N·m, which reduces resistance during low-speed movement. The aluminum frame weighs 1.9 kg, reducing the supported mass in vertical-axis and moving-stage installations. The motor can achieve a theoretical acceleration of 145,746 rad/s² when operated within its electrical and mechanical limits, supporting fast indexing movements without adding excessive actuator weight.
