Product Description:

The MT502A1-T1C1 servo motor is manufactured by Kollmorgen within the MTC Servo Motors series. This brushless unit converts controlled three-phase power into precise rotary motion for axes that need moderate torque and tight velocity regulation in automated assemblies. A 130 mm square mounting face and a 19 mm output shaft allow straightforward integration with gearboxes, timing pulleys, or couplings, while an internal resolver or encoder path enables closed-loop feedback to the drive. The motor serves as the prime mover in packaging machinery, light machine-tool spindles, and indexing tables where repeatable positioning is required.

At a continuous line current of 2.4 A RMS, the motor can produce a continuous stall torque of 3.1 N·m without exceeding its thermal limits. During rated operation, it turns at 2200 rpm and supplies a mechanical output of 0.6 kW, matching many low-power motion axes. The back electromotive force constant is 76.7 V RMS/krpm, indicating the generated voltage per unit of speed and helping the drive maintain proper commutation. Winding resistance is 12.33 Ω, allowing the controller to predict copper losses accurately. The unit accepts up to 250 V RMS of line voltage, which protects the insulation system from excessive electrical stress during dynamic braking events.

Short-term loads can be met with a peak torque of 10.0 N·m when the drive supplies up to 10.4 A RMS. Electrical response is influenced by the phase inductance of 58.0 mH, which filters switching ripple and allows current to rise smoothly during rapid acceleration. The laminated rotor has an inertia of 0.00051 kg·m², so it accelerates quickly while resisting minor load disturbances. The overall mass is 5.9 kg, which eases handling during installation while adding thermal mass. Heat accumulation progresses slowly because the motor has a 34-minute thermal time constant. A 6 mm keyway secures the output shaft to connected mechanical hardware and helps prevent slippage under load.
