In automation setups, the MHD093C-035-PG1-BA acts as the "muscle" of motion systems, converting electrical energy into precise mechanical motion. Its design integrates seamlessly with servo drives, enabling tight synchronization in complex processes like robotic assembly, conveyor indexing, or CNC machining. What sets the MHD093C-035-PG1-BA apart is its balance of power and efficiency: it maintains consistent performance under varying loads, reducing energy waste while ensuring smooth operation—key for minimizing wear on connected equipment.

Technical Specifications

Key Features and Benefits

The MHD093C-035-PG1-BA excels in dynamic performance, with a rapid acceleration capability that ensures quick response to drive commands—essential for high-cycle applications like packaging lines or pick-and-place robots. Its 20-bit absolute encoder eliminates the need for homing cycles after power loss, reducing downtime and simplifying system startup.

Durability is another standout trait. The motor’s robust construction, including a stainless-steel shaft and IP65 protection at the shaft end, resists dust, moisture, and minor fluid exposure—ideal for factory floors where environmental conditions can be harsh. Thermal management is optimized through efficient heat dissipation, allowing the MHD093C-035-PG1-BA to operate continuously at full load without overheating, extending service life.

Integration is streamlined, too. The motor’s standard mounting flange and electrical interfaces align with industry norms, making it easy to retrofit into existing systems or pair with Bosch Rexroth’s IndraDrive series drives. This compatibility reduces setup time and ensures seamless communication between components, enhancing overall system efficiency.

Application Scenarios

The MHD093C-035-PG1-BA thrives in industries demanding precise motion control. In automotive manufacturing, it powers robotic arms for welding and part assembly, where its 3.5 Nm torque and 3000 rpm speed enable consistent, repeatable movements—critical for maintaining weld quality or aligning components with sub-millimeter accuracy.

In packaging machinery, the MHD093C-035-PG1-BA drives conveyor indexing and filling mechanisms. Its rapid response ensures packages are positioned correctly for labeling or sealing, even at high production speeds, reducing waste from misaligned items.

Machine tool applications also benefit: the motor’s smooth speed regulation enhances the precision of CNC lathes and milling machines, producing tighter tolerances on machined parts. For food and beverage processing, its IP54 housing resists dust and splashes, making it suitable for clean-in-place environments where hygiene is paramount.
