Fuji Electric 6MBP100NA060-01: An Integrated Power Module for Compact Motor Drives
Introduction and Key Highlights
The Fuji Electric 6MBP100NA060-01 is a highly integrated Power Integrated Module (PIM) that streamlines the design of low-power AC motor drives and servo systems. It combines a three-phase IGBT inverter, a brake chopper, and multiple protection features into a single, compact package. Key specifications include 600V collector-emitter voltage and 100A collector current. This integration delivers two primary engineering benefits: simplified system assembly and enhanced operational reliability. By consolidating critical power stages, the module reduces both PCB space and the parasitic inductance that can plague discrete component layouts. For applications requiring a robust, all-in-one solution for motor control up to ~30kW, the 6MBP100NA060-01 offers an optimal balance of performance and design efficiency.
Key Parameter Overview
Decoding the Specs for Integrated Drive Performance
The technical specifications of the 6MBP100NA060-01 are engineered to deliver reliability and efficiency in motor control applications. Each parameter contributes directly to the module's performance within a system, from electrical efficiency to thermal stability.
| Parameter | Value | Engineering Value & Interpretation |
|---|---|---|
| Collector-Emitter Voltage (Vces) | 600V | Provides a safe operating margin for applications running on 200-240V AC lines, protecting against voltage spikes common in industrial environments. |
| Collector Current (Ic) | 100A | Supports sufficient power handling for a wide range of small to medium-sized AC motors, enabling robust torque and speed control. |
| Collector-Emitter Saturation Voltage (Vce(sat)) | 2.2V (Typ) / 2.7V (Max) | This low value signifies minimal voltage drop across the IGBT when it is fully on. It's analogous to low resistance, directly reducing conduction losses and improving the overall energy efficiency of the Variable Frequency Drive (VFD). |
| Topology | IGBT 6-pack + Brake Chopper + NTC Thermistor | This all-in-one configuration is the core value proposition. It simplifies the bill of materials (BOM), reduces assembly complexity, and minimizes potential points of failure compared to a design using discrete components. |
| Overheat Protection Temperature (Tj) | 150°C | The integrated NTC thermistor enables precise monitoring of the module's internal temperature, allowing the system controller to trigger an alarm or shutdown before catastrophic failure occurs, which is a critical feature for system reliability. |

Application Scenarios & Value
Achieving System-Level Benefits in Compact Industrial Automation
The 6MBP100NA060-01 is best suited for low-power motor control systems where space, reliability, and design simplicity are critical decision factors. Its integrated nature provides tangible benefits in applications like conveyor systems, packaging machinery, and small-scale robotics.
Consider the engineering challenge of designing a compact Variable Frequency Drive (VFD) for a multi-axis conveyor system. Using discrete components would require separate IGBTs, freewheeling diodes, a brake chopper circuit for regenerative energy, and a temperature sensor, all demanding significant PCB real estate and complex routing. This complexity introduces parasitic inductance, which can cause voltage overshoots and increase EMI, complicating regulatory compliance. The 6MBP100NA060-01 directly solves this. Its PIM architecture co-packages the 600V / 100A IGBT inverter stage with the brake chopper. This is like having a pre-built power core; it minimizes the electrical path lengths between components, drastically reducing parasitic inductance and simplifying thermal management to a single heatsink interface. The built-in NTC thermistor further enhances value by providing a direct feedback loop for overheat protection, a crucial element for ensuring long-term reliability in demanding start-stop cycles typical of robotic servo drives. While this module is ideal for its current class, for systems demanding higher power handling, the related 6MBP150NA060 offers a higher current rating of 150A within a similar integrated framework.
Technical Deep Dive
A Closer Look at the PIM Architecture for Enhanced Reliability
The design philosophy behind the 6MBP100NA060-01 centers on system-level simplification without compromising performance. The Power Integrated Module (PIM) approach is more than just packaging convenience; it's a strategic design choice that directly impacts electrical and thermal performance. By integrating the three-phase inverter, brake unit, and protection circuits, Fuji Electric has created a component that behaves more predictably than a discrete assembly.
Think of the internal layout of a PIM as a professionally designed city road network, whereas a discrete solution is like a city with roads built ad-hoc over time. The PIM's optimized internal connections ensure that current flows evenly with minimal detours (low parasitic inductance), preventing "traffic jams" (voltage spikes) during high-speed switching events. This inherent electrical stability often simplifies the requirements for external Snubber Circuit design and helps in achieving EMC compliance more easily. Furthermore, mounting all major heat-generating components onto a single, unified substrate ensures more uniform thermal distribution. This prevents localized "hot spots" that can occur in discrete layouts, leading to more effective cooling and ultimately contributing to a longer operational lifespan for the entire power system.
Frequently Asked Questions (FAQ)
What is the primary benefit of the integrated brake chopper in the 6MBP100NA060-01?
The integrated brake chopper provides a ready-made solution for dissipating regenerative energy generated when an AC motor decelerates rapidly. This prevents the DC bus voltage from rising to dangerous levels, protecting the module and other components without requiring an external braking circuit.
How does the integrated NTC thermistor improve system safety?
The NTC thermistor allows for real-time monitoring of the IGBT junction temperature. This enables the implementation of a proactive over-temperature protection system, which can trigger an alarm or a controlled shutdown, preventing thermal runaway and catastrophic module failure—a critical feature for unattended industrial equipment.
What does the Vce(sat) of 2.7V (Max) mean for my design?
A low Collector-Emitter Saturation Voltage (Vce(sat)) means less power is wasted as heat during the conduction phase. This directly translates to higher energy efficiency for the motor drive and reduces the size and cost of the required heatsink, enabling a more compact and cost-effective overall system design.
Is this module suitable for a 400V AC line application?
No, the 600V Vces rating is designed for applications on 200-240V AC lines. For 380V/400V AC industrial lines, a module with a Vces rating of 1200V is the standard engineering choice to ensure sufficient safety margin against line transients.
Can I parallel these modules for higher current output?
While IGBT paralleling is a common technique, it is not recommended for PIMs or IPMs like the 6MBP100NA060-01 due to the integrated gate drive and control logic. These modules are designed as self-contained power stages. For higher current requirements, selecting a single module with a higher native current rating, such as the 6MBP150RA060, is the correct design approach.
Engineering Perspective
From an engineer's viewpoint, the 6MBP100NA060-01 is a problem-solver for space-constrained, cost-sensitive motor control projects. It abstracts away much of the complexity associated with power stage layout, thermal balancing, and basic protection. This allows design teams to focus their efforts on higher-level control algorithms and software features, accelerating the development cycle while building on a reliable, pre-validated power foundation from Fuji Electric.
