USAGED-13A21SE belongs to Yaskawa legacy USAGED fully enclosed natural cooling AC permanent magnet servo series with rated 1.3kW power rating, factory fitted with built-in DC24V power-off electromagnetic brake and UTOPH-81AWF incremental rotary encoder configuration, final suffix SE stands for special customized cable pin definition and European standard connector layout exclusive for overseas OEM matching CACR-SR series servo amplifier system. This obsolete traditional servo motor targets heavy-load CNC feed axes, vertical spindle automation equipment and high-cycle reciprocating positioning machinery requiring reliable power-off shaft holding performance.

USAGED represents totally enclosed self-cooling base servo series; numeric 13 denotes 1.3kW rated power grade; letter A means standard stator winding layout and universal internal mechanical structure; digit 2 refers to solid keyed output shaft design; next digit 1 indicates dual separated rear round connectors for independent power cable and encoder wiring; suffix S marks customized encoder pin assignment, trailing E stands for EU specification structural and wiring modification compared to standard domestic S variant.

This motor accepts three-phase AC 200V~230V, 50/60Hz industrial standard input power supply. Continuous rated output power is 1.3kW with full-load rated operating current reaching 11.7A, fixed synchronous rated rotating speed at 1500rpm and continuous rated torque of 8.28Nm; instantaneous peak overload torque can achieve three times rated torque to handle heavy startup acceleration and sudden load shock conditions.Independent DC24V powered built-in electromagnetic brake releases shaft when coil gets energized and mechanically locks output shaft immediately upon brake power cut to prevent vertical axis free falling under gravity load. Equipped UTOPH-81AWF differential line driver incremental encoder with fixed pulse resolution and exclusive SE-version pinout definition which matches designated CACR-SR driver without wire rearrangement. Stator winding adopts Class F insulation grade with embedded winding temperature sensing circuit transmitting overheat signal to matched servo drive for automatic thermal protection, internal surge absorption components are integrated inside terminal wiring compartment to improve anti-interference against industrial power surge and electromagnetic field disturbance.

Complete motor housing is fully sealed with IP50 protection grade adopting natural casing convection heat dissipation without auxiliary cooling fan; drive end solid output shaft comes with standard built-in parallel keyway for rigid coupling connection with ball screw or speed reducer, integrated rear brake housing increases overall axial body length versus non-brake models, net motor weight is approximately 6.3kg with standard flange mounting dimension conforming to original factory installation standard.Normal continuous working ambient temperature range covers 0℃ to +40℃, permissible long-term storage temperature spans -20℃ to +70℃; applicable working relative humidity keeps between 5%RH~80%RH under non-condensation surrounding environment. When installation altitude exceeds 1000 meters above sea level, users need to derate continuous output load properly to compensate deteriorated natural heat dissipation efficiency at high elevation. The motor withstands 10Hz~55Hz regular industrial vibration amplitude; installation locations with corrosive chemical gas, continuous liquid splash and dense conductive dust accumulation are strictly prohibited.

USAGED-13A21SE is originally designated to pair Yaskawa CACR-SR large frame servo amplifier series including standard and E-version customized EU firmware drivers, supporting two mainstream external command input types: ±10VDC analog voltage speed instruction and differential pulse position command transmitted from upper CNC controller or PLC unit to realize continuous speed regulation and high-precision repeated positioning operation. Thanks to integrated power-off brake structure, vertical mounting equipment saves extra external mechanical locking fixture for anti-drop protection during unexpected total power failure.

Cooperation between built-in motor sensors and matched servo drive realizes multi-layer safety protection mechanism. Winding over-temperature triggers driver overload protection stop; encoder wire open-circuit or poor contact will trigger dedicated encoder error alarm on servo panel; stator winding short-circuit and input abnormal overcurrent activate hardware overcurrent shutdown protection. Abnormal open/short circuit of built-in brake coil will trigger auxiliary warning signal on corresponding driver fault display, all internal circuit components are designed with noise suppression structure to resist on-site industrial electromagnetic interference.

Direct equipment replacement requires identical original USAGED-13A21SE spare part; standard S-version 13A21S or non-brake variant motors cannot substitute directly unless servo drive completes full parameter reset and connector wiring modification. Before disassembling for bearing replacement, brake overhaul or encoder maintenance work, users must fully disconnect main three-phase power and brake DC power supply and wait minimum 15 minutes for complete discharge of servo internal DC bus capacitor to avoid residual high voltage electric shock risk.Regular maintenance items include tightening power and encoder connector terminal screws every three months, replenishing high temperature resistant bearing grease after accumulated 8000 running hours and cleaning casing surface accumulated dust every half year to retain original heat dissipation performance. Random modification on encoder pin definition or brake wiring layout will lead to out-of-control motor running and permanent servo drive fault locking status.

The servo motor is widely deployed for heavy-load X/Y/Z feed axes of medium-large CNC lathes, vertical machining centers, automated vertical feeding machinery and rotary indexing equipment of assembly production lines, especially suitable for vertically installed driving positions with frequent start-stop cyclic operation and strict power-off anti-falling positioning requirement under medium to heavy load working condition.
