Features:
- Selectable step resolutions from 200 to 10,000 steps per revolution enable precise positioning with step angles as fine as 0.036°.
- High torque density with 1.5 Nm nominal torque and 1.70 Nm holding torque in a compact 57.2 mm square flange package.
- Flexible voltage compatibility with maximum supply of 230 VAC or 325 VDC and multiple phase current options for optimized performance.
The VRDM 368/50 LNB offers exceptional positioning flexibility with eight selectable step resolutions ranging from 200 to 10,000 steps per revolution. This translates to step angles from 1.8° down to an ultra-fine 0.036°, allowing engineers to balance between speed and positional accuracy based on application requirements.
Despite its compact 57.2 mm square flange, the VRDM 368/50 LNB delivers impressive torque performance with 1.5 Nm nominal torque and 1.70 Nm holding torque. This high torque density makes it suitable for direct-drive applications that would typically require larger motors or gearboxes. The motor achieves this through optimized 3-phase winding configurations, available in HH (5.8 A), N (1.9 A), or H (0.9 A) current ratings.
The VRDM 368/50 LNB accepts a wide range of supply voltages—up to 230 VAC or 325 VDC—enabling seamless integration with various drive platforms. This voltage flexibility allows system designers to optimize power delivery based on speed-torque requirements. For applications requiring higher torque output, the motor can be combined with planetary gearboxes including PLE 40, PLE 60, and PLS 70 series.
The VRDM 368/50 LNB Berger Lahr 3-phase stepping motor may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Industrial Automation and Robotics: Used for conveyor belt control, automated assembly lines, and precise displacement of robot joints.
- Packaging and Printing Equipment: Provides consistent synchronization in labeling, film feeding, or printhead positioning.
- CNC Machining: Used as feed drives for small milling machines or engraving machines.
- Medical Equipment: Used in laboratory analytical instruments requiring high reliability and microstepping control.
- Overheat Protection: The motor is typically equipped with a thermistor (such as a PTC) to monitor winding temperature and prevent motor burnout due to overload.
- Insulation and Protection Rating: Typically has an IP40 or higher protection rating (depending on the specific sub-model), protecting against dust and minor oil contamination.
- Fault Diagnosis: When used with a compatible drive (such as the Twin Line series), faults such as phase loss, short circuit, or stall can be identified.
- Installation Environment: Ensure the motor is installed in a well-ventilated location and use a coupling to ensure the concentricity of the motor shaft and load shaft to reduce bearing wear.
- Wiring Specifications: This model is a three-phase stepper motor. Wiring must strictly follow the driver wiring diagram to avoid incorrect phase connections that could cause motor vibration or reverse rotation.
- Upgrade Path:If the existing system is aging, it is recommended to check the driver's compatibility. Modernization upgrades typically involve replacing the older driver with a Schneider Electric Lexium series driver to obtain more advanced bus control (such as EtherCAT or CANopen).
- Spare Parts Replacement: When replacing an older model, ensure that the flange dimensions, shaft diameter, and encoder interface are consistent.
