AC Brushless Servo Motor – PANASONIC MSMA082A1C
The MSMA082A1C is an AC brushless servo motor rated at 750 W, belonging to the MINAS A series by Panasonic Industrial Devices. The part number decodes as: MSMA family (high-inertia motors, 80 mm frame), 750 W, 200 V AC supply, integrated incremental encoder at 2,500 pulses/rev, and standard mechanical configuration with keyed shaft (suffix “A1C”). It is compatible with Panasonic MSDA and MSD series drives (MINAS A) and is documented on machining centres, CNC milling machines and axis drive systems from various machine-tool builders.
The servo motor is the electromechanical actuator that converts the CNC position or speed reference into real axis movement: it delivers precise, responsive torque thanks to continuous real-time feedback from its built-in encoder. If it fails — due to a winding fault, damaged encoder or worn bearings — the affected axis loses control, the CNC raises a following-error alarm and production stops immediately.
Panasonic Industrial Devices & Solutions (formerly Matsushita Electric Industrial, renamed Panasonic Corporation in 2008) has produced the MINAS servo line since 1991. Current series MINAS A5 and A6 use high-resolution serial encoders (17 bit, 131,072 p/r); the MINAS A (MSMA) series with 2,500 p/r incremental encoder is therefore legacy / discontinued, still widespread in the installed base but available only as used stock, surplus or through specialist repair.
