Product Description:

The MTC504B2-S1C1 is a brushless servo motor produced by Kollmorgen within the MTC Servo Motors series. This motor is installed in positioning axes, feeders, and packaging stations where closed-loop speed and torque control are required for repeatable motion profiles. Its electromagnetic design converts drive current into rotational force so that automated equipment can accelerate, decelerate, and hold commanded positions with minimal overshoot during repeated production cycles.

The stator current that the windings can carry continuously is 8.6 ARMS, and this value sets the thermal limit for steady operation at rated load. A torque constant of 0.775 N-m/ARMS links that line current to the mechanical torque the drive can generate, which helps relate current demand to output torque during axis setup. Electrical dynamics are influenced by the phase inductance of 10.5 mH, which moderates current rise during fast command changes, and by the phase resistance of 1.18 ohms, which determines copper losses that must be dissipated by the housing. The motor can be connected to amplifiers that supply up to 250 VRMS line-to-line, allowing it to reach full rated output without voltage saturation.

Peak mechanical performance reaches 21.7 N-m for brief overloads such as indexing or punch cycles, while the rotor can spin stably up to 4000 rpm when commanded by the drive. A rotor inertia of 0.00093 kg-m² balances fast acceleration with load matching, aiding motion controllers that demand quick response without excessive current spikes. After power is removed, the winding and iron mass cool toward ambient following a thermal time constant of 40 min, which helps when estimating recovery time between heavy-duty cycles. Additional parameters such as an eight-pole magnetic structure, a stall torque of 6.6 N-m at 40 °C, and a rated power output of 2.4 kW support its use in medium-power industrial axes.
