SGMAH is Yaskawa Sigma-II medium inertia permanent magnet AC servo motor series; digit 04 means rated output power 400W; the first letter A represents single/three-phase AC200V input voltage standard specification; digit 1 stands for 16-bit absolute serial encoder with battery-backed absolute position detection; digit 6 defines split dual aviation plug connectors, separate power connector and encoder connector on motor housing; letter C stands for built-in 24VDC electromagnetic holding brake; letter D refers to customized factory special specification for bus matching; suffix -0Y is OEM exclusive customized variant code for special equipment matching.

The motor is designed for AC200V servo driving system, rated continuous power reaches 400W with rated continuous working current of 2.8A, rated continuous torque is 1.27N·m and short-time peak overload torque can reach three times rated torque for rapid acceleration and instant heavy-load startup. Rated operating speed and maximum allowable speed are both fixed at 3000rpm. Equipped with built-in 16-bit absolute serial encoder, it can realize power-off position memory without zero return after power interruption. Motor winding adopts Class B insulation grade, passing 1500VAC one-minute dielectric withstand test and insulation resistance over 10MΩ under 500VDC detection condition. The built-in brake is powered by DC24V, holding torque matches rated motor torque for mechanical locking during power failure.

It uses standard 60mm square flange mounting dimension, output shaft is straight shaft with standard flat keyway and end threaded tapping hole matching code 6 definition; two independent round aviation plugs are separately arranged on motor side casing for power cable and feedback encoder cable respectively, different from ordinary integrated single plug design. The fully closed motor shell achieves IP55 protection grade with natural self-cooling structure without auxiliary cooling fan; overall net weight is approximately 1.45kg due to built-in brake module. Standard shaft oil seal is equipped as customized C option for oil mist and dust prevention in harsh working conditions.

Permitted continuous operation ambient temperature ranges from 0℃ to +40℃, storage temperature for idle powered-off motor is -20℃ ~ +85℃. Working environment relative humidity keeps between 20% and 80% with no surface condensation allowed. Installation location should stay away from corrosive gas, dense dust and oil mist atmosphere; derated operation is mandatory when installation altitude exceeds 1000 meters above sea level. Vibration grade complies with V15 standard for stable low-noise operation.

Matching standard servo driver is SGDM-04ADA series Sigma-II amplifier, D customized code supports bus-type servo driver for fieldbus control system connection, and -0Y OEM version is specially configured for designated automation production equipment. This motor is widely applied to precision indexing fixture, automatic dispensing equipment, PCB processing machinery, small conveying positioning axis and customized special automation production line with brake locking requirement.

Low rotor inertia Sigma-II design realizes fast dynamic response and short positioning settling time; built-in brake improves equipment safety for vertical-axis anti-falling protection; split dual aviation plug structure simplifies on-site wiring, maintenance and later cable replacement; absolute encoder eliminates repetitive origin reset work after equipment power cut, greatly improving production efficiency of automated equipment.
