Product Information

Product Family: MDSKS

The Lenze 15001631 MDSKSRS056-33 is a permanent magnet AC synchronous servo motor from the MDSKS series, designed for precise, high-dynamic motion control applications in industrial automation. Built in a compact 056 frame size, this unit delivers a rated power output of 0.26 kW alongside a rated torque of 0.75 Nm and a standstill torque of 0.85 Nm. Operating at a rated speed of 3,300 RPM with maximum speeds up to 6,000 RPM, it provides precise dynamic response in packaging machinery, material handling, and light assembly lines. Thermal energy generated during operational cycles is managed via self-ventilated natural convection cooling, removing the requirement for external fan units.

Interfacing the motor with industrial motion controllers relies on standard plug-and-socket connections for power and signal transfer, alongside an embedded 2-pole resolver feedback system. The MDSKSRS056-33 connects directly to multiple Lenze drive platforms, including Lenze 9300 Servo Drives, Lenze 9400 HighLine Servo Drives, and Lenze i700 Cabinet Servo Inverters. Commissioning a replacement unit requires confirming matching mechanical mounting dimensions and shaft geometry while aligning drive-side parameter profiles and resolver feedback settings. When restoring operation on an active machine line, ABC Industrial Parts can assist with sourcing and technical verification of replacement units.

Diagnostic tracking and thermal protection are maintained through internal PTC thermistor or KTY temperature sensors embedded directly in the motor windings. Signals from these sensors route straight to the connected drive amplifier, which evaluates thermal thresholds alongside resolver signal integrity and phase current levels. Initial troubleshooting on the machine floor should focus on checking wiring connections, plug seating, and cable integrity between the drive and motor terminals. Internal winding faults or resolver hardware damage require off-line refurbishment or complete motor exchange, where ABC Industrial Parts provides tested replacement units to restore production uptime.

Communication and System Integration

The Lenze 15001631 MDSKSRS056-33 servo motor utilizes standard plug-and-socket connection technology for motor power leads and feedback signal lines. Position control and rotor angle detection are provided by an integrated 2-pole resolver, which delivers continuous feedback signals resistant to mechanical vibration and ambient temperature fluctuations.

System integration covers direct compatibility with Lenze drive architectures, including the 9300 Servo Drive, 9400 HighLine Servo Drive, and i700 Cabinet Servo Inverter series. The drive interface evaluates the resolver signal directly for closed-loop motion control, while monitoring internal motor temperature via integrated thermal sensor connections.

Diagnostics and Status Indication

Continuous thermal monitoring of the MDSKSRS056-33 motor is performed via internal PTC thermistor or KTY temperature sensors embedded in the stator windings. The connected Lenze servo drive evaluates these sensor inputs in real time to prevent thermal overload and protect motor insulation.

Because the physical motor casing features no external status LEDs or displays, fault detection is handled entirely at the drive level. Drive alarms indicate potential issues such as overtemperature conditions, loss of resolver feedback continuity, phase imbalances, or overcurrent states during operation.

Replacement and Spare Part Considerations

The Lenze MDSKS motor family, including model MDSKSRS056-33 (part number 15001631), has been discontinued by the manufacturer. Installing an identical direct replacement model avoids mechanical modifications to mounting plates, shaft couplings, and motor cables on existing machinery.

When commissioning a replacement motor, confirm that frame size 056 dimensions, shaft orientation, and 2-pole resolver specifications match the original unit. Drive parameters for current limits (0.9 A rated, 1.0 A standstill) and resolver feedback settings must be verified on the connected Lenze 9300, 9400, or i700 drive before returning the system to full operation.
