Kollmorgen’s E33NRFB-LNN-NS-00 step motor is among the 3 rotor stack series designed for extra efficiency and high torque. During operation, this motor’s connection can fall in either of the following categories: parallel, unipolar, or series. The E33NRFB-LNN-NS-00 step motor is 2 phased and its estimated holding torque is 4.69 Nm to 6.55 Nm. The rated current stands at 2.7 to 5.5 Amps DC while its phase resistance is estimated to range between 0.55 to 2.17 Ohms. The unit’s thermal resistance is 2.0⁰C/Watt while the phase inductance stands at 5.7 mH to 22.9 mH and its detent torque is estimated to be 0.45 Nm. The motor’s rotor moment of inertia stands at 0.176kgm²X10^-3and the net weight is estimated to be 3.45 kgs.

When you want to estimate the thermal resistance of this unit, you need to do it while the motor is unmounted and still hanging on still air. Also, the windings/lead designation on the model number of your unit is what determines whether you use series, unipolar or parallel connection.
