Rexroth VMA 035 BR 001-D Hydraulic Motor / Supply Module

 

 

Product Overview

The Bosch Rexroth VMA 035 BR 001-D is NOT a hydraulic motor. It is actually a Servodyn VM series power supply / DC link module used in Rexroth Indramat servo drive systems.

It is typically used in:

• Indramat Servodyn systems
• Multi-axis servo drive cabinets
• CNC and industrial motion control systems

Function Principle

This module works as a central power unit in servo systems:

• Converts AC input → stable DC link (≈670V)
• Feeds multiple servo drive amplifiers
• Supports energy recovery (regenerative braking)
• Stabilizes motion system power supply

It is a system-level power backbone, not a motor.

Advantages & Features

• Stable DC bus power for multi-axis servo systems
• Supports regenerative energy feedback
• Compact rack module design (100 mm width)
• High reliability for continuous industrial operation
• Designed for CNC and automation systems
• Modular integration in Indramat drive cabinets

Applications

• CNC machine tools
• Industrial automation systems
• Servo multi-axis control cabinets
• Robotics systems
• Printing and packaging machinery
• Legacy Indramat / Rexroth Servodyn systems

Precautions

• Must be used only in Rexroth Servodyn / VM system architecture
• Dangerous high voltage (≈670V DC bus)
• Incorrect wiring may damage entire drive system
• Requires proper cooling and cabinet ventilation
• Not compatible with modern standalone VFD systems
• Installation only by qualified engineers
