Product Description:
The TTE-2043-3025-B-38 is a permanent-magnet direct-drive motor manufactured by Kollmorgen for the Inland Direct Drive Motors series. Designed for integration into servo tables and precision machinery, the motor delivers torque directly at the shaft, eliminating intermediate transmissions and reducing positioning error in automated equipment. It is supplied as a frameless stator-rotor set for direct integration into user-designed housings.
At the machine’s continuous operating point, the motor supplies 4.90 N-m while drawing 9.6 Arms from the drive. This torque-to-current relationship is represented by a 0.52 N-m/Arms torque constant, allowing the controller to predict load response from commanded current. When the shaft turns at the rated 2500 rpm, the electromagnetic work produced equates to 1.07 kW of mechanical output, making the motor suitable for modest-power rotary axes. The thermal design sustains a steady rated torque of 4.08 N-m with a 20-minute thermal time constant before the winding reaches thermal equilibrium. Electrical characteristics include a 160 VDC bus rating, a back-EMF constant of 33.2 Vrms per krpm, a phase resistance of 0.74 ohm, and an inductance of 2.90 mH. These parameters influence servo amplifier sizing and current-loop bandwidth.
During rapid indexing or disturbance rejection, the motor can deliver 16.4 N-m for short intervals while the drive supplies 38.4 Arms. These transient ratings provide acceleration headroom without exceeding the winding limits. The maximum speed is 6000 rpm, so feedback devices and couplings must be rated accordingly. A rotor inertia of 2.09 kg-cm² moderates acceleration rates and simplifies tuning when the load inertia is similar. With a total mass of 4.35 kg, the assembly adds minimal load to moving axes while providing enough iron to support magnetic flux and consistent temperature-rise control.
