Product Description:

The MT504B1-R1C1 is a brushless servo motor produced by Kollmorgen within the MTC Servo Motors series. Its eight-pole rotor and rare-earth magnets allow tight velocity and position control in automated packaging lines, material-handling gantries, and indexing machinery. The motor converts supplied electrical power into rotary motion, while the drive regulates its operation through sinusoidal current control. This arrangement gives the motor the dynamic response needed for demanding industrial automation tasks.

The winding is rated for a continuous line current of 8.6 A RMS, so the motor can deliver steady torque without overheating when sized correctly. Thermal energy moves slowly through the frame, as indicated by a thermal time constant of 40 min; this value supports cycle-time calculations and enclosure cooling design. Electrical power output reaches 2.4 kW at the rated operating point, and the shaft can sustain a speed of 4000 rpm under that load. The back electromotive force constant is 46.9 V RMS/krpm, which helps determine the voltage needed at different operating speeds. A DC resistance of 1.18 Ω and a phase inductance of 10.5 mH influence current-loop tuning and drive selection.

The motor can generate a peak torque of 21.7 N-m for rapid acceleration when the drive supplies a peak line current of 34.7 A RMS. The insulation supports a line-to-line voltage of up to 250 V RMS, permitting connection to many 230 V class inverters. The rotor inertia is only 0.00093 kg-m², helping reduce settling times during start-stop duty cycles. A torque sensitivity of 0.775 N-m/A RMS links commanded current to delivered torque for straightforward control scaling. Continuous stall torque is 7.03 N-m at 25 °C and decreases to 6.6 N-m at 40 °C, providing two operating values for load and temperature calculations.
