Product Description:

The Kollmorgen MT504B1-R1C1 Servo Motor is a compact and high performance motion control solution. It delivers 2.5 HP (1.9 kW) rated power output. Its efficient torque and acceleration characteristics enable consistent operation.

The MT504B1 servo motor from the MTC series offers 4.9 lb-ft stall torque at 40 °C and 5.2 lb-ft at 25 °C. Continuous current rating for the motor is 8.7 Amps RMS while peak torque reaches 15.7 lb-ft. Peak current measures 34.7 Amps RMS. The motor’s maximum operating speed is 3300 RPM. The motor supports a back EMF of 45.8 VRMS/kRPM. The theoretical acceleration is 22733 rad/sec². Torque sensitivity of the servo motor is 0.56 lb-ft/Amp RMS. It has a DC resistance of 1.115 Ohms at 25 °C and an inductance of 10.5 mH. Maximum voltage is 250 Volts RMS. Rotor inertia for the servo motor is measured at 0.00069 lb-ft-sec². The weight of the servo motor without a brake is 17.6 lb. The motor's viscous damping constant is 0.037 lb-ft/kRPM and the static friction torque is 0.085 lb-ft. The servo motor’s thermal time constant is 40 minutes. These specifications ensure reliable performance under various load conditions.

The MT504B1 servo motor integrates a high resolution optical encoder with 8192 pulses per revolution that enables precise position feedback and enhanced motion control accuracy. The encoder's high line count facilitates finer interpolation for improved velocity and position loop performance in servo applications. Mechanical tolerances of the motor shaft exceed typical industry standards with reduced shaft runout, improved perpendicularity and enhanced concentricity. The servo motor is fully compatible with Kollmorgen SERVOSTAR digital servo drives. The servo motor supports seamless integration and optimal control loop performance in closed loop motion systems.
