The 6SP44X-040CTAN is a permanent magnet synchronous servo motor manufactured by RELIANCE. It features fully sealed housing with anti-corrosion surface coating and compact internal winding layout, equipped with built-in high precision absolute encoder and optional power-off electromagnetic brake. Designed to pair with RELIANCE matching servo drives for high-precision motion control, this motor is supplied as original spare part and new configuration component for automated industrial equipment retrofitting and production line building.

6SP denotes RELIANCE standard servo motor series coding for permanent magnet synchronous type.44 indicates motor frame dimension specification.X represents customized mechanical structure variant of shaft and mounting flange.040 stands for rated 4.0kW power grade.CTAN is configuration suffix covering brake assembly, output shaft form, encoder specification and installation dimensional standard.

Rated input is three-phase AC220V, rated output power 4.0kW, rated continuous torque 19.1Nm, rated rotational speed 2000rpm. Insulation grade is Class F, motor body protection rating IP65. Operating ambient temperature ranges from -10℃ to +40℃, storage temperature from -30℃ to +70℃, relative humidity 5%RH~90%RH under non-condensing condition. Integrated 23-bit absolute position encoder, optional holding brake structure, energy efficiency conforms to IE4 high-efficiency grade and vibration complies with industrial N-level acceptance criteria.

Terminal block is arranged for three-phase main power wiring and brake power connection. Dedicated encoder socket links to matching servo drive to transfer real-time rotor position, rotational speed and winding temperature feedback signals. No independent fieldbus communication interface is set on motor body; position information is transmitted via industrial bus including EtherCAT, Modbus and Profinet through the paired servo drive unit. No spare expansion communication terminals are reserved on the motor.

It converts electrical energy into precise mechanical rotary output under the command of matched servo driver to accomplish closed-loop control of positioning, constant-speed operation and constant-torque output for mechanical loads. Embedded temperature sensor feeds winding temperature data back to drive to trigger overheat protection. The optional electromagnetic brake locks motor shaft immediately upon power failure to avoid free sliding of suspended loads. Built-in encoder delivers continuous rotor position feedback to guarantee high response and high precision of whole servo motion control system.

It is widely deployed in CNC machine feeding axes, automatic packaging machinery, textile processing equipment, lithium battery assembly production lines, automatic cutting and welding devices, and multi-axis manipulator transmission structure for automotive parts manufacturing lines.

Cut off the total input power of matched servo drive fully before disassembly or periodic maintenance and wait over 15 minutes to discharge residual stored energy in drive circuit. Perform quarterly maintenance to wipe dust and oil stains on motor outer casing, check connection tightness of power cable and encoder cable terminals and cable ageing status. When abnormal running noise, excessive heating or positioning offset occurs during operation, inspect mechanical stuck fault and wire damage preferentially before motor replacement. Unauthorized disassembly of stator, rotor and internal winding modification are prohibited; replace with brand-new complete original motor after professional inspection confirms permanent mechanical or winding damage.
