Lenze MDSKSBS071-13 Synchronous Servo Motor
Product Introduction
The Lenze MDSKSBS071-13 is a high-performance synchronous servo motor. It converts 325V AC into precise rotary motion. Rated power stands at 3.2 kW.
Rated current is 7 A, while peak current reaches 32 A for short overloads. Moreover, this motor achieves a rated speed of 3700 r/min. The Lenze MDSKSBS071-13 suits demanding applications like CNC machines, robotics, and packaging equipment.
Technical Specifications
Electrical ratings are precisely defined. Rated voltage equals 325 V AC at a frequency of 185 Hz. Rated current sits at 7 A. Maximum current reaches 32 A for temporary overloads.
Speed and torque performance is robust. Rated speed is 3700 r/min. The built-in brake delivers 12 Nm holding torque. Brake operation requires 24 V DC at 0.75 A.
Feedback comes from a resolver. This provides reliable position and speed data even in harsh conditions. Cooling is through natural convection, so no external fan is needed.
Mechanical and Environmental Data
Protection rating is IP54 per EN 60529. This means the MDSKSBS071-13 resists dust ingress and water splashes from any direction.
Insulation class is F, allowing temperature rises up to 155°C. Operating ambient temperature ranges from -20°C to +40°C.
Weight of the motor alone is approximately 5.3 kg. For shipping, gross weight is 5.8 kg including packaging.
Built-in Brake Features
The Lenze MDSKSBS071-13 includes an integrated electromagnetic holding brake. Brake torque is 12.0 Nm. Brake current is 0.75 A at 24 V DC.
This brake engages when power is removed. Therefore, it holds the motor shaft safely during power loss or emergency stops. Applications like vertical axes and hoists benefit greatly from this feature.
Installation Guidelines
First, mount the MDSKSBS071-13 on a rigid base using the four flange holes. Ensure the shaft aligns perfectly with the load. Second, connect the power cables to the terminal box. Third, wire the resolver feedback cable with proper shielding.
Furthermore, connect the 24 V DC brake supply separately from the motor power. The brake must open before the motor moves. Finally, ground the motor housing to the system earth.

Frequently Asked Questions (FAQ)
1. What drive works with the MDSKSBS071-13?
The Lenze MDSKSBS071-13 pairs with Lenze 9300 or 9400 series servo drives. Ensure the drive provides 325V AC output and resolver interface.
2. Can I replace the resolver with an encoder?
Technically yes, but the MDSKSBS071-13 ships with a resolver. Conversion requires mechanical adapter and drive parameter changes. Consult Lenze for official modification kits.
3. How do I test the holding brake?
Apply 24 V DC to the brake leads. You should hear a clicking sound. Then manually turn the shaft—it should rotate freely. Remove voltage and confirm the shaft locks.
4. What is the maximum speed of this motor?
Rated speed is 3700 rpm. However, the Lenze MDSKSBS071-13 can run up to 5000 rpm with reduced torque. Exceeding 3700 rpm requires field weakening in the drive.
5. Is this motor suitable for washdown environments?
IP54 offers splash resistance, not full washdown protection. For high-pressure cleaning, choose an IP65 or IP67 motor. The MDSKSBS071-13 works in dusty, damp areas but avoid direct water jets.
