Product Description:
The MTB504B1-9191-010 is a brushless servo motor produced by Kollmorgen for the MTC Servo Motors series. It serves as the rotary actuator in automation cells that demand precise speed and torque regulation, converting controlled three-phase voltage from a drive into accurate shaft motion for indexing tables, gantry axes, and similar equipment. With the factory-installed brake, the overall housing length reaches 255.3 mm, allowing integration into compact mechanical envelopes.
The motor has a rated output of 2.4 kW at a nominal speed of 4000 rpm. At that operating point, it draws a continuous line current of 8.6 A RMS, and when the shaft is locked at 25 °C, it can hold a load with 7.03 N·m of stall torque. A torque constant of 0.775 N·m/A RMS relates drive current to mechanical output. A DC resistance of 1.18 Ω and an inductance of 10.5 mH indicate the electrical time constants that influence current regulation. The winding insulation tolerates a maximum line-to-line voltage of 250 V RMS, matching common medium-voltage servo amplifiers.
Short-duration demands are supported by a peak line current of 34.7 A RMS, which produces up to 21.7 N·m of torque for rapid acceleration or disturbance rejection. Rotor inertia is 0.00093 kg·m², providing a balance between quick response and load smoothing. A thermal time constant of 40 minutes indicates how slowly the stator temperature rises under overload. The continuous stall torque is 6.6 N·m at 40 °C, indicating sustained capability in warmer enclosures. The integrated brake engages at 90 V DC to secure vertical axes when holding force is required. A back-EMF constant of 46.9 V RMS/krpm helps determine the drive voltage needed for field weakening at high speeds.
