by Okuma
The Okuma MDUF-15-2844-MA is a high-performance MDU Servo Drives series servo spindle drive unit engineered to meet rigorous Okuma machine tool standards. This multi-axis servo spindle drive supports a Rated Input Voltage of DC 283–325V and delivers a Rated Output Voltage of AC 200V, 3-phase power, ensuring stable operation under demanding conditions. With an Operating Frequency of 50/60 Hz and a robust SCCR rating of 50kA RMS SYM, the MDUF-15-2844-MA provides both dynamic response and safety against short-circuit faults. The unit’s flexible Cooling Method—offering either air or liquid cooling depending on configuration—maintains optimal thermal performance across a variety of industrial environments. Designed, manufactured, and quality-assured by Okuma, this drive strikes an ideal balance of power density and reliability.
Configured with precision in mind, the MDUF-15-2844-MA integrates a high-resolution Feedback Device encoder interface and standard Electrical Connections using modular plug-in servo drive connectors for quick installation and maintenance. Its Overload Capacity of up to 110–120% of rated load accommodates transient torque demands without compromising system stability. The unit’s Input Voltage specification aligns with typical 480V 3-phase AC supplies when configured, while its Rated Power output (refer to datasheet for exact kW/HP rating) matches the performance requirements of modern CNC spindles. The drive’s Unit Type classification as a Servo Spindle Drive Unit underscores its role in precision motion control.
Operational deployment of the MDUF-15-2844-MA is facilitated by its wide Ambient Temperature Range of 0°C to 40°C and adherence to Okuma’s mounting configuration standards, allowing seamless integration into existing machine tool architectures. The drive’s compact Physical Dimensions (length, width, and height per datasheet) and moderate Weight enable installation at elevations up to 1,000 meters with minimal vibration sensitivity. Its advanced cooling options ensure consistent performance under continuous operation, while standard modular connectors simplify wiring for motor phases labeled U, V, W and signal links such as PA, PB, PC, PD, E1A–E2D, and charge/discharge terminals CHG/RES. This attention to detail reduces downtime and streamlines preventive maintenance.
Integration of the MDUF-15-2844-MA into multi-axis CNC systems is straightforward, thanks to its compatibility with Okuma control architectures and industry-standard encoder inputs. Engineers can leverage the drive’s flexible mounting and electrical interface to retrofit existing machinery or design new automation lines with minimal rework. Its configurable Cooling Method and wide Ambient Temperature Range make it suitable for applications ranging from high-speed milling and turning to complex robotic spindles. Whether deployed in machine tools, milling centers, or specialized automation cells, the MDUF-15-2844-MA delivers precise, reliable performance for the most demanding industrial environments.
