SanRex PD10M44OH7B06 | Integrated PIM for High-Efficiency, Compact Motor Control
The SanRex PD10M44OH7B06 is an intelligently designed Power Integrated Module (PIM) engineered to streamline the development of low-power motor drives and power conversion systems. By co-packaging a three-phase converter, a three-phase inverter, and a brake chopper into a single, thermally optimized housing, this module addresses the critical engineering challenges of space constraint, assembly complexity, and system reliability.
Application Scenarios & Engineering Value
The true value of the PD10M44OH7B06 is realized when its architecture is mapped to specific application demands. It's not just a component; it's a solution-enabler for modern power electronics.
- Compact Variable Frequency Drives (VFDs): In applications like conveyor belts, pumps, and fans, board space is at a premium. The integrated CIB (Converter-Inverter-Brake) topology of this PIM eliminates the need for multiple discrete components, reducing the overall drive footprint by up to 40% and drastically simplifying PCB layout and assembly.
- HVAC Systems: For residential and commercial air conditioning compressors and air handlers, efficiency and acoustic noise are paramount. The module's optimized internal layout minimizes stray inductance, enabling cleaner switching waveforms. This reduces EMI generation and allows for higher switching frequencies, which can push acoustic noise outside the audible range.
- Robotic Servo Drives: Precision and dynamic response are non-negotiable in robotics. The integrated brake chopper provides robust control over motor deceleration and regenerative energy, ensuring rapid and repeatable positioning. This level of integration is critical for developing the compact, high-performance servo systems needed for articulated robotic arms.

Frequently Asked Questions (FAQ)
Our engineers often encounter the following questions when integrating PIMs like the SanRex PD10M44OH7B06:
- How does a PIM simplify thermal management compared to discrete components?A PIM centralizes all major heat sources onto a single, flat baseplate. This allows for the use of one larger, more efficient heatsink instead of multiple smaller, less effective ones. It guarantees a defined thermal path and simplifies thermal modeling, leading to a more predictable and reliable thermal design.
- What are the key considerations for the gate drive design with this module?While the PIM simplifies the power stage, a robust gate drive is still crucial. Key considerations include ensuring a low-impedance path, providing separate turn-on and turn-off gate resistors for fine-tuning switching speed, and implementing undervoltage lockout (UVLO).
