Product Description:

The MTC302B1-M2C1 is a brushless servo motor manufactured by Kollmorgen within the MTC Servo Motors series. It is intended for closed-loop industrial automation where commanded current is converted into precise shaft torque and velocity, supporting indexing tables, pick-and-place axes, and other motion stages that demand repeatable positioning. Its brushless design supports responsive motion control and consistent operation in automated axis systems.

During dynamic operation, the motor’s integral holding brake engages at 24 VDC, supplying mechanical restraint whenever power to the drive is removed. At 25 °C, the continuous stall capability reaches 1.35 N·m, which is the torque the shaft can sustain indefinitely without overheating. The stator can draw a steady 4.44 ARMS from the amplifier, while its insulation tolerates up to 250 VRMS line potential for use with standard factory mains. For brief transients, the phase conductors handle 16.5 ARMS, enabling rapid acceleration. The 11.5 mH phase inductance filters current ripple, and the 2.24 Ω DC resistance sets copper losses that must be dissipated by the lamination stack. Electrical feedback to the controller is proportional to rotor speed because the back electromotive force is 17.8 VRMS per kilorevolution. Static friction of 0.030 N·m must be overcome at startup, and the motor supports 3.22 N·m of peak torque for fast indexing moves.

At its rated speed of 6000 rpm, the shaft delivers 0.72 kW of mechanical power while staying within the 1.27 N·m continuous stall limit at 40 °C. The rotor inertia is 0.0000465 kg·m², allowing commanded speed changes with limited kinetic energy storage. A thermal time constant of 22 min shows that the windings warm gradually, which supports short duty-cycle overloads without immediate derating. The torque constant of 0.294 N·m per ampere links commanded current to shaft torque and helps simplify current-loop tuning for tight servo control.
