Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 15001176 (model MDSKSRS071-03) is a permanent magnet AC synchronous servo motor from the Lenze MDSKS Servo Motors family designed for high-dynamic positioning and motion control applications. Featuring a compact size 071 frame and 6-pole construction, this motor generates a rated torque of 3.0 Nm and a standstill torque of 3.8 Nm at speeds up to 3000 RPM. Built with natural convection cooling, the fan-free design eliminates mechanical fan maintenance while providing quiet operation. An integrated KTY84-130 temperature sensor embedded in the stator windings continuously monitors thermal status to prevent overload, while an IP65 rated enclosure protects internal components against dust and moisture in harsh production environments.
For interface connectivity, the unit utilizes a heavy-duty SpeedTec circular power connector alongside a 12-pin circular feedback interface linked to an internal 2-pole resolver. Integrating a replacement motor into a machine requires drive configuration alignment rather than simple plug-and-play installation. The MDSKSRS071-03 operates with Lenze drive series including the 9300 Servo Inverters, 9400 HighLine Servo Drives, i700 Servo Inverters, and i950 Servo Drives. Commissioning involves transferring motor parameters from the Lenze motor database into software engineering environments such as Lenze Global Drive Control (GDC), EASY Starter, or Drive System Designer (DSD), followed by verifying feedback settings and electronic zero-point alignment. Support from ABC Industrial Parts can assist technical teams in sourcing exact-match replacement units to restore machine operation efficiently.
System diagnostics and troubleshooting focus on verifying electrical integrity across the motor's primary systems. Technicians can measure phase-to-phase winding resistance across terminals U-V, V-W, and W-U using a digital multimeter to verify balanced resistance values across the stator windings. The internal KTY84-130 thermal sensor can be verified across its terminals, where a normal reading ranges between 580 and 600 Ohms at approximately 20°C to confirm the absence of open or short circuits. Resolver excitation and sine/cosine coil resistances can also be checked, along with electronic zero-point verification through connected drive software. When internal winding damage, insulation failure, or physical wear occurs, hardware components cannot be serviced in the field, making a tested replacement or professional repair through ABC Industrial Parts the most effective solution.

Programming and Configuration
Configuring the Lenze 15001176 MDSKSRS071-03 AC servo motor involves integrating motor parameters into Lenze inverter commissioning tools. Software suites such as Lenze Global Drive Control (GDC), EASY Starter, and Drive System Designer (DSD) facilitate exact motor identification by pulling pre-configured data sets from the standard Lenze motor database. Selecting the MDSKSRS071-03 profile populates key parameters including 3.0 Nm rated torque, 3.8 Nm standstill torque, 2.9 A rated current, 3.5 A standstill current, and 6-pole electrical geometry.
Proper setup requires linking the drive parameter profile with the motor's 2-pole resolver and KTY84-130 thermal sensor. During replacement, commissioning engineers must verify that the speed feedback scaling, pole count, and thermal trip thresholds match the installed inverter's parameter set. Executing a zero-point alignment procedure via EASY Starter or GDC confirms accurate phase offset between the resolver feedback signal and the motor's rotor position, ensuring optimal torque delivery and dynamic response across dynamic positioning applications.
Communication and System Integration
The Lenze 15001176 MDSKSRS071-03 motor interfaces physically with industrial power and control networks using standardized industrial circular connectors. Electrical power connections are established via a rugged SpeedTec circular power connector, offering reliable contact resistance and quick-locking mechanical engagement for fast installation. Feedback signals, motor temperature monitoring, and resolver wiring are routed separately through a dedicated 12-pin circular connector.
Signal integration connects the motor's 2-pole resolver feedback and KTY84-130 thermal protection directly to compatible Lenze drive hardware, including the 9300 Servo Inverter, 9400 HighLine, i700, and i950 servo drive platforms. The 12-pin feedback interface delivers precise sine and cosine analog feedback signals back to the drive's encoder evaluation circuit, enabling accurate closed-loop speed and position control in packaging machinery, material handling systems, and automated assembly lines.
Diagnostics and Status Indication
Diagnostic evaluation of the Lenze 15001176 MDSKSRS071-03 AC servo motor relies on direct electrical measurements across the power, thermal, and resolver circuits. Checking winding resistance phase-to-phase (U-V, V-W, W-U) using a digital multimeter allows maintenance personnel to verify balance across all stator coils, where inconsistent readings indicate localized short circuits or phase breakdown.
Thermal circuit testing requires measuring resistance across the KTY84-130 sensor terminals. At an ambient temperature of approximately 20°C, intact sensor resistance measures between 580 and 600 Ohms, where infinite resistance or short circuit values highlight a damaged sensor loop. Feedback integrity is evaluated by checking excitation and sine/cosine rotor coil resistances on the 12-pin connector and running electronic zero-point calibration routines within drive software tools.
Replacement and Spare Part Considerations
When replacing a Lenze 15001176 MDSKSRS071-03 motor, service personnel must ensure complete hardware and electrical parameter compatibility. As part of the legacy Lenze MDSKS series, this unit features a compact size 071 frame design, natural convection cooling, and IP65 enclosure protection. Although newer installations may utilize current Lenze MCS or m500 series motors, maintaining existing machinery with an identical 15001176 unit avoids mechanical mounting modifications, bracket adjustments, or cabling redesigns.
To complete a successful replacement, engineers must verify that the replacement motor matches the original 2-pole resolver feedback specification and connection pinouts. Before restoring power, drive parameter sets in Lenze 9300, 9400, i700, or i950 inverters should be verified against the motor database in EASY Starter or GDC. Performing a zero-point resolver alignment after mounting ensures smooth angular performance and prevents drive overcurrent trips upon initial power-up.
