Product Description:

The MT1502A2-R1C1 is a brushless servo motor manufactured by Kollmorgen within the MTC Servo Motors series. As a rotary actuator, the unit couples to industrial machinery where a digital drive controls precise velocity and position loops. By supplying sinusoidal current to the windings, the drive enables the motor to generate controllable shaft torque for packaging equipment, semiconductor handling systems, and light pick-and-place axes.

Under continuous stall conditions, the stator draws 2.21 A RMS and produces 0.466 N·m of torque at 25 °C, providing a thermal reference for steady-duty sizing. The back EMF constant is 12.2 V RMS/krpm, which helps establish the bus voltage required from the inverter at a given operating speed. A phase inductance of 13.2 mH limits current ripple and influences the response of the current control loop. The line-to-line resistance is 6.85 Ω and contributes to copper losses while the motor is operating. Phase-to-phase insulation withstands up to 250 V RMS, establishing the permissible drive output voltage. The eight-pole rotor produces an electrical frequency that is four times the mechanical rotation rate.

The shaft can reach 6000 rpm during short moves, allowing rapid motion on axes with suitable mechanical loads. Transient current can rise to 7.2 A RMS and produce 1.25 N·m of peak torque for acceleration or disturbance rejection. Continuous energy conversion is limited by a rated output of 0.23 kW, while static friction of 0.0072 N·m must be overcome during startup. The torque constant is 0.202 N·m/A RMS, giving the controller a linear relationship between commanded current and generated torque. Heat passes from the winding to the case through a thermal resistance of 1.33 °C/W, and the 12-minute thermal time constant permits brief overloads before the winding reaches its temperature limit. The housing weighs 1.1 kg, which supports compact mounting and limits the additional mass placed on small gantries.
