Panasonic MSM, MDM, and MHM series servo motors are mid-tier Japanese-OEM brushless AC servo motors stocked by Flextech Industrial Supplies for Malaysian machine builders requiring 23-bit absolute encoder servo capability, three-inertia-class motor flexibility within a single MINAS A6 drive platform, and Panasonic ecosystem integration across PLC, servo drive, and servo motor.
Panasonic servo motors occupy the mid tier in the Malaysian servo motor market – competitive with Delta ECM-B3 on absolute encoder resolution (both 23-bit) while providing a broader inertia-class selection (MSM/MDM/MHM within a single MINAS A6 drive platform), Panasonic Industrial Malaysia direct OEM technical support, and single-vendor integration with Panasonic FP-series PLCs and MINAS A6 drives through Flextech’s Puchong facility. Quotations are provided within 24-48 hours with same-day Klang Valley dispatch on standard MSM and MDM models.
About Panasonic MINAS Servo Motors: Three-Inertia-Class Architecture
Panasonic Industry's MSM, MDM, and MHM servo motor series are engineered as matched-inertia-class components for the MINAS A6 servo drive platform - three distinct mechanical frame designs optimised for different load-to-motor inertia ratios, all sharing the same 23-bit absolute encoder interface and MINAS A6 amplifier parameter architecture.
The three-inertia-class architecture provides Malaysian machine builders a unique mechanical design tool: the same MINAS A6 servo drive hardware controls all three motor inertia classes by updating frame-specific parameter tables, without changing the servo amplifier. A machine builder can switch from MSM (fast-acceleration labelling axis) to MHM (high-torque index table drive) by specifying a different motor frame - not a different drive. This flexibility reduces Flextech's stocking complexity and simplifies Malaysian machine builder spare drive inventory.
Panasonic Servo Motor Series Comparison
| Series | Class | Power Range | Speed | Inertia | Best Application |
| MSM | Low inertia | 50W-5 kW | 2,000-3,000 rpm | Minimal | Fast-acceleration, light load |
| MDM | Medium inertia | 100W-15 kW | 2,000-3,000 rpm | Medium | General machine tool, packaging |
| MHM | Medium inertia, high torque | 400W-7.5 kW | 2,000-3,000 rpm | Medium | Heavy load, rotary index |
Panasonic MSM series (Minimal inertia, Small frame) are the fastest-accelerating Panasonic servo motors - minimal rotor inertia enables maximum acceleration rate at a given servo drive peak torque. MSM motors are the correct specification for Malaysian high-speed insertion machine axes, high-speed labelling servo drives, and PCB component pick-and-place axes where settle time after each positioning move is the production cycle time bottleneck. MSM covers 50W (50 watts) to 5 kW - the widest power range of the three series.
Panasonic MDM series (Medium inertia, Dynamic) are the general-purpose Panasonic servo motor for the majority of Malaysian machine builder applications - packaging line registration drives, CNC feed axes, conveyor indexing, and assembly station positioning. MDM balances speed capability and torque delivery across a wide range of mechanical loads, covering 100W to 15 kW (the full MINAS A6 power range at the high end). MDM is the default specification when application-specific inertia matching has not been performed.
Panasonic MHM series (Medium inertia, High torque/Moment of inertia) provides higher continuous torque density than MDM in an equivalent frame size - the correct specification for applications where the mechanical load demands maximum sustained torque at lower speed: robotic joint drives, rotary index table drives, press brake back gauge drives, and heavy material handler axes in Malaysian automotive and metalworking plants. MHM covers 400W to 7.5 kW.
Technical Specifications
Encoder: 23-bit absolute multi-turn encoder standard across all MSM, MDM, and MHM models. 8,388,608 counts per revolution. Multi-turn capability retains absolute position across multiple shaft revolutions - suitable for applications with extended travel requiring multi-turn position tracking without mechanical stops.
Absolute position retention: Encoder battery backup retains position data across power cycles. Machine power-up proceeds without homing sequence - the drive reads absolute encoder position directly after power-on. Standard for Malaysian machines where power interruption must not require machine re-zeroing before production can resume.
Peak torque: 300% of rated continuous torque, 3-second duration. MSM low-inertia motors achieve the fastest torque rise rate at given peak current - relevant for applications where acceleration time is the primary servo performance metric.
IP protection: IP65 standard across MSM, MDM, and MHM series. Dust-tight and water-jet resistant per IEC 60529. IP67 variants available on select models for Malaysian F&B applications requiring temporary submersion protection during floor cleaning. Specify at order.
Brake option: Holding brake (24 VDC release) available as factory option on most MSM, MDM, and MHM frame sizes. Brake holds motor shaft when servo is powered off - required for vertical axes and gravity-loaded applications in Malaysian machines where back-drive under gravity creates safety or positioning hazard on power loss.
Three-Inertia-Class Selection: Practical Guide for Malaysian Machine Builders
Selecting between MSM, MDM, and MHM requires a load inertia calculation - comparing the mechanical load inertia (referred to the motor shaft) against the motor rotor inertia.
Load-to-motor inertia ratio below 3:1 - specify MSM (lowest rotor inertia). The load inertia is small relative to the motor - servo response is fast and stable with standard MINAS A6 gain settings.
Load-to-motor inertia ratio 3:1 to 10:1 - specify MDM (medium inertia). Load inertia is moderate - MINAS A6 auto-tuning manages gain adjustment within the standard tunable range.
Load-to-motor inertia ratio above 10:1, high torque demand - specify MHM (high torque) or add a gearbox to reduce the load inertia ratio. Malaysian heavy material handling and rotary index table applications typically exceed 10:1 ratio on direct-drive motor configurations.
When the ratio cannot be calculated - specify MDM as the safe default, enable MINAS A6 Real-Time Auto Tuning (RTAT), and observe servo response during commissioning. RTAT's adaptive gain adjustment can compensate for moderate inertia mismatch - typically within 5:1 to 15:1 ratio without manual intervention.
Applications in Malaysian Manufacturing
High-speed semiconductor handler (Penang OSAT) - MSM low-inertia motors on die-to-tray transfer axes in IC handler machines where move-and-settle time below 150 ms per cycle is required at high production throughput.
Packaging machinery (Malaysia-wide) - MDM medium-inertia motors on form-fill-seal registration drives, labelling servo axes, and cartoning index drives where balanced speed-torque performance and 23-bit absolute encoder eliminate production restart delays after power loss.
Robotic welding positioners (Selangor, Johor) - MHM high-torque motors on rotary positioner table drives in automotive robotic welding cells, where sustained high torque at low speed during welding operations is the primary motor performance requirement.
Panasonic FP PLC ecosystem - Malaysian plants running Panasonic FP7 PLCs specify MSM/MDM/MHM motors paired with MINAS A6 drives for complete Panasonic ecosystem continuity: single-vendor PLC + servo drive + servo motor supply from Flextech on one quotation.
