Product Description:

The MT702B1-F1A1 is a servo motor manufactured by Kollmorgen for the MTC Servo Motors series. Intended for precise velocity and position regulation in automated machinery, it converts drive current into controlled mechanical rotation for pick-and-place modules, web-handling lines, and gantry axes. A 174 mm square flange provides straightforward face mounting, while an integral shaft seal protects the internal bearings from coolant spray commonly found inside industrial enclosures.

During continuous operation, the motor draws 25.2 A RMS, permitting it to sustain a stall torque of 22.0 N·m at 40 °C without thermal overload. At the nominal shaft speed of 3000 rpm, the electromagnetic design delivers 4.6 kW of mechanical power, a rating suitable for mid-range conveyor drives and indexing tables. Copper losses are moderated by a phase resistance of 0.222 Ω, so heat rise stays manageable when the drive regulates current during demanding duty cycles. For rapid acceleration, the winding can produce up to 56.0 N·m of torque in short bursts to overcome inertia or process friction. An inductance of 6.2 mH helps the current loop filter switching harmonics and maintain stable servo bandwidth.

The motor has a torque constant of 0.87 N·m/A RMS, giving the controller a predictable torque increase for each ampere of current. Back electromotive force measures 52.9 VRMS/kRPM, which helps determine the required DC-bus margin when regenerative energy returns during deceleration. Dynamic response is aided by a rotor inertia of 0.00515 kg·m², balancing load matching with fast indexing moves. When full machine throughput is required, the windings tolerate a peak line current of 78.3 A RMS. A 10 mm key and 35 mm shaft diameter provide secure transmission of surge torque without mechanical slip. An 8192-PPR incremental encoder supplies high-resolution feedback, allowing the servo loops to maintain accurate position and velocity control at high speeds.
