6SP501-9P0CTNN belongs to RELIANCE 6SP series permanent magnet synchronous servo motor. It uses fully sealed metal housing with anti-corrosion outer coating, compact high-density internal winding structure, equipped with built-in high-resolution absolute encoder and standard power-off holding brake. It is specially designed to cooperate with RELIANCE matched servo drivers for high-precision closed-loop motion control, supplied for new machine assembly and industrial equipment maintenance spare replacement.

6SP: Series code of RELIANCE permanent magnet synchronous servo motor.501: Code for motor frame size and basic mechanical dimension specification.9P0: Rated power coding corresponding to 9.0kW rated output power.CTNN: Configuration suffix defining brake configuration, output shaft type, encoder specification and installation standard.

Rated input three-phase AC220V, rated output power 9.0kW, rated continuous torque 43.2Nm, rated rotational speed 2000rpm. Insulation grade is Class F, motor body protection grade IP65. Operating ambient temperature ranges from -10℃ to +40℃, storage temperature -30℃~+70℃, relative humidity 5%RH~90%RH under non-condensing environment. It is fitted with 23-bit absolute encoder and integrated electromagnetic holding brake, energy efficiency reaches IE4 standard and vibration level conforms to industrial N-grade specification.

Independent terminal blocks are reserved for three-phase main power wiring and brake power connection. Special dedicated encoder connector connects supporting servo drive to transmit real-time rotor position, speed and winding temperature feedback signals. No fieldbus communication port is arranged on motor body; all motion data uploads to upper control system via EtherCAT, Modbus or Profinet industrial bus through matched servo drive unit. No extra expandable communication interfaces are reserved.

It converts electric energy into stable precise mechanical rotation under the regulation of supporting servo driver, realizing high-precision positioning, constant-speed operation and constant torque closed-loop control of mechanical loads. Built-in temperature detection component feeds back winding temperature to servo drive to activate overheat protection. The integrated power-off brake locks motor output shaft instantly when power supply is cut off to avoid load falling or shifting. Real-time position feedback from internal encoder ensures fast dynamic response and high positioning precision of the whole servo control system.

It is widely used for heavy-load feed axes of large CNC machine tools, automatic packaging production lines, textile spinning and weaving equipment, new energy lithium battery forming equipment, automatic cutting and welding devices, and heavy-load transmission of multi-axis manipulators in automobile component processing workshops.

Fully cut off input power of matched servo drive before disassembly or regular maintenance, wait more than 15 minutes to release residual capacitance energy inside drive circuit. Conduct quarterly maintenance to remove dust and oil contamination on motor casing, check connection tightness and ageing condition of power cable and encoder cable terminals. When abnormal noise, excessive temperature rise or positioning deviation appears during operation, check mechanical jamming and wire damage preferentially before motor replacement. Unauthorized disassembly of stator, rotor and internal winding modification are strictly prohibited; replace complete original motor after professional inspection confirms permanent mechanical or winding damage.
