Product Description:

Kollmorgen manufactures the TTE-2950-1010-C-06 within the Inland Direct Drive Motors series. This frameless brushless motor mounts directly to a load shaft, eliminating belts or gear trains and allowing a control drive to command torque and position without mechanical compliance. This arrangement is suited to semiconductor tooling, compact gantries, and rotary actuators that require high stiffness and minimal inertia while relying on closed-loop servo control for accurate movement.

The motor delivers continuous torque of 2.0 Nm while drawing 8.33 A, and these values indicate the load that can be sustained during steady operation without exceeding the winding temperature limits. The winding has an inductance of 1.8 mH, allowing current to rise quickly while providing enough filtering for smooth commutation. Its phase resistance is 0.712 Ω, which contributes to the copper losses that the cooling path must remove. At rated speed, the back electromotive force increases in proportion to velocity, with a constant of 25.5 V/krpm that supports DC-bus sizing and regeneration planning. A torque constant of 0.244 Nm/A allows the control electronics to convert commanded torque into precise current references across the operating range.

For short dynamic events, the winding can accept up to 90 A and produce 16.3 Nm of torque for rapid indexing or overcoming static friction. The mechanical speed capability reaches 4500 rpm, with the limit based on rotor balance and available voltage headroom. The bus voltage must remain below 115 VDC to prevent dielectric stress while remaining high enough to support operation throughout the intended speed range. These short-term current and torque allowances support brief acceleration and deceleration periods without subjecting the motor to sustained overload conditions.
