Lenze 30034624 MDSKSRS056-33 Synchronous Servo Motor
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 30034624 MDSKSRS056-33 is a compact three-phase AC synchronous servo motor from the Lenze MDSKS series. Designed with a permanent-magnet rotor and a frame size of 056, this self-ventilated convection-cooled motor provides high dynamic response for precise positioning and motion control in space-constrained industrial installations. It operates at a nominal rated speed of 3300 rpm and can reach a maximum mechanical speed of 6000 rpm, delivering a rated power output of 0.26 kW, a rated torque of 0.75 Nm, a standstill torque of 0.85 Nm, and a standstill current of 0.9 A.
Cabling for power, resolver feedback, and thermal monitoring is handled via SpeedTec circular threaded connectors. The unit features an integrated 2-pole resolver mechanism for closed-loop speed and position feedback, as well as an embedded KTY 84-130 thermal sensor for stator temperature protection. Putting a spare motor into service requires pairing with a compatible servo inverter—such as the Lenze 9300 Servo Inverters or Lenze L-force Servo Inverters including the i700, i900, and EVS9300—and loading the correct motor data using Lenze EASY Engineering Tools or L-force Engineer software. When preparing a replacement unit, ABC Industrial Parts can assist with sourcing tested replacement motors to ensure rapid system re-commissioning.
Field troubleshooting relies primarily on drive-based monitoring and basic static testing. Technicians can measure resistance across the KTY 84-130 thermal sensor pins on the feedback connector to confirm stator temperature integrity, or check sine/cosine excitation feedback signals via diagnostic software on the connected servo drive. Internal winding faults or resolver degradation cannot be serviced at the machine level; replacing the faulty motor or securing a tested exchange unit through ABC Industrial Parts provides the fastest route to restoring production line operation.

Programming and Configuration
System configuration for the Lenze 30034624 servo motor is managed through Lenze engineering software suits, specifically Lenze EASY Engineering Tools and L-force Engineer software. These engineering environments allow commissioning engineers to upload motor parameter files, fine-tune speed and position control loops, and assign operational safety thresholds on host drive controllers.
When installing a new or replacement motor with Lenze 9300 Servo Inverters or L-force Servo Inverters (i700, i900, or EVS9300), the drive profile must match the motor's operational specifications. Parameters governing standstill current (0.9 A), rated torque (0.75 Nm), rated speed (3300 rpm), and resolver feedback scaling must be aligned within the drive memory to ensure smooth vector control and accurate thermal monitoring.
Communication and System Integration
The MDSKSRS056-33 features SpeedTec circular threaded connectors that combine power delivery, thermal protection wiring, and resolver feedback into reliable quick-locking interfaces. This circular connector setup helps protect signal wires from interference and prevents loose connections in high-vibration applications such as packaging machines, gantry units, and textile positioning systems.
Feedback communication is driven by an integrated 2-pole resolver ('RS' option) that transmits continuous analog sine and cosine signals to the connected inverter. Concurrently, the embedded KTY 84-130 temperature sensor outputs continuous resistance measurements over feedback lines, enabling host Lenze drives to monitor thermal conditions continuously and trip safely before over-temperature damage occurs.
Diagnostics and Status Indication
Diagnostic routines for the Lenze 30034624 motor involve direct electrical measurements and drive-level feedback analysis. Maintenance technicians can evaluate the condition of the stator winding insulation and temperature sensor by measuring resistance across the KTY 84-130 pins on the feedback connector using a calibrated digital multimeter.
Signal feedback integrity can be verified through the status parameters of the connected Lenze servo drive. Software diagnostics analyze carrier excitation and incoming sine/cosine transformer signals, aiding in the fast detection of cable discontinuities, phase imbalance, or feedback failure.
Replacement and Spare Part Considerations
The Lenze MDSKS motor series is discontinued and succeeded by the Lenze MCS series. When replacing a failed 30034624 motor, using an exact MDSKSRS056-33 replacement unit guarantees direct mechanical drop-in installation, maintaining shaft alignments, mounting hole patterns, and original SpeedTec cable plug compatibility without line modifications.
Prior to putting a replacement motor into active service, technicians should verify that the drive parameter setup matches the motor nameplate values, including the 0.26 kW power rating and 0.85 Nm standstill torque limit. Ensuring that the connected Lenze drive correctly recognizes the 2-pole resolver and KTY 84-130 sensor inputs prevents nuisance trips and ensures precise positioning accuracy upon restart.
