Product Description:
Kollmorgen’s MTC302A1-M2C1 is a brushless servo motor in the MTC Servo Motors series. It provides closed-loop speed and position control for conveyors, pick-and-place heads, and other precision axes in factory automation. Coupled to a matching drive, the unit converts regulated current into shaft torque without open-loop slip, giving machine builders a compact rotary actuator for moderate-power tasks. Its brushless design uses electronic commutation rather than mechanical brushes, reducing wear during repetitive motion. The motor can support applications that require controlled acceleration, accurate positioning, and consistent speed under changing loads.
At its rated operating point, the motor delivers 0.59 kW of mechanical output while turning at a rated speed of 4500 rpm. Continuous stall torque reaches 1.37 N-m at 25 °C and is supported by a phase current of 2.44 A RMS, indicating the load that the thermal limits permit continuously. The 7.77 Ω DC resistance and the 35 mH line-to-line inductance affect current rise and voltage demand during rapid transients. A back electromotive-force constant of 32.6 V RMS/krpm relates shaft speed to generated voltage and helps with compatible drive selection. At 40 °C, the allowable continuous stall torque decreases to 1.29 N-m. A torque sensitivity of 0.540 N-m per ampere supports controller gain calculations and helps establish the relationship between commanded current and motor torque.
Dynamic events are supported by a peak torque capacity of 3.23 N-m when the drive permits up to 9.0 A RMS of phase current. The rotor has an inertia of only 0.0000465 kg·m², enabling rapid acceleration and responsive changes in speed. The winding system accepts up to 250 V RMS line-to-line, providing the electrical capacity required for operation with a compatible servo drive. A 24 VDC brake supply energizes the holding brake when braking action is required. The motor has a total weight of 3.6 kg, including the brake assembly. Its maximum operating speed matches the rated speed, allowing the drive to use a single velocity ceiling for motion commands and protective limits.
