Product Description:

Kollmorgen builds the MTC1504A1-E2D1 as part of its MTC Servo Motors series for compact, medium-speed positioning axes in automated machinery. This brushless synchronous motor converts electrical energy into rotational motion that can be commanded by a digital drive, allowing precise velocity and torque regulation in indexing tables, light conveyors, and small robotics. An integral electromagnetic brake powered by 24 VDC keeps the shaft fixed when power is removed, supporting vertical loads and operator safety.

The motor’s permitted top speed is 6000 rpm. This is the highest mechanical output frequency before the rotor and bearings reach their rated limits. During steady operation, it generates up to 0.37 kW of mechanical power while drawing a continuous phase current of 2.93 ARMS. That current produces the rated electromagnetic field because the three-phase windings have 9.3 mH of inductance and 3.77 Ω of resistance. For holding loads at zero speed, the armature develops 0.790 N-m of stall torque at 25 °C, a value slightly reduced to 0.742 N-m at 40 °C as copper temperature rises. The back electromotive force constant is 15.6 VRMS/krpm, so the drive must supply roughly 15.6 V for every 1000 rpm of commanded speed and must not exceed the 250 VRMS line limit. Static friction of 0.0130 N-m means only minimal drive current is required to initiate motion. Thermal resistance of 1.37 °C/W shows how quickly stator heat transfers to the housing.

For short acceleration bursts, the motor can deliver 2.42 N-m of torque when the drive supplies up to 11 ARMS, extending motion capability beyond the continuous region without violating magnetic or thermal limits. The conversion efficiency of current to torque is set by the constant of 0.258 N-m/ARMS, giving the controller a predictable gain for closed-loop tuning. A thermal time constant of 15 min shows how quickly the winding temperature follows load changes, so brief overloads can be tolerated before active cooling or derating are required.
