At its rated operating point it draws from a 3AC 400 V bus, delivers Pn=2.5 kW at Nn=2000 rpm, with a stall torque M0=15 Nm and rated torque MN=11.9 Nm — the stall/rated torque spread is what tells the integrator how much headroom the motor has for acceleration peaks before the drive hits its torque limit. ## Mechanical and encoder build The motor carries a shaft-height-90 mm frame, an angle plug for the power and feedback cabling, a feather key on the shaft, and a holding brake fitted at the factory — the brake is what locks the axis when the drive is de-energised, so any retrofit on a vertical or held-load axis must keep the brake option matched. Feedback is an incremental encoder at 2500 increments per revolution, output through the angle plug — incremental rather than absolute, so the drive needs to run the homing sequence on every power-up before the axis is allowed to move. ## Environmental rating and panel integration The housing is rated IP65 with the sealing ring fitted, which means the motor tolerates splash and dust on a machine envelope but is not rated for high-pressure washdown — adequate for typical machine-tool and light assembly environments, but a food-and-bev line would push beyond this rating. ## Lifecycle and sourcing posture Compliance record carries RoHS conformity since 01-01-18 and a REACH Article 33 candidate-list disclosure obligation — the EU environmental paperwork you would expect to see on a current-generation Siemens motion product is on file.","metaTitle":"Siemens 1FL6090-1AC61-2AB1 Servomotor, 2.5 kW, 15 Nm, IP65","metaDescription":"Siemens 1FL6090-1AC61-2AB1 SIMOTICS S-1FL6 servomotor, 2.5 kW, 15 Nm, 400 V, IP65, NRND lifecycle.
