It is rated for 0.94 kW of continuous power at 600 V DC, with a rated speed of 6,000 rpm and a continuous torque of 1.5 Nm at the 100K rating, along with a stall torque of 3 Nm and a maximum torque of 10.5 Nm for short bursts. The unit weighs about 5.1 kg (5.8 kg with a brake) and uses a natural‑convection IMB5 enclosure with flange 1 and a rotatable power connector for flexible installation. It includes a rotatable absolute encoder; CG0 variants employ a 24‑bit single‑turn encoder plus a 12‑bit multi‑turn memory (AM24DQI) accessed via DRIVE‑CLiQ, enabling reliable position feedback across power cycles. Electrical data list winding resistance around 1.145 Ω and inductance about 8.6 mH, with an electrical time constant near 7.5 ms and a mechanical time constant around 3.8 ms, supporting quick dynamic response in closed‑loop control. In typical SINAMICS drive configurations, the motor has a rated inverter current of 5 A and a maximum inverter current of 10 A, providing a scalable range from precise micro‑positioning to higher‑torque operation. This SIMOTICS S motor is commonly used in automation, robotics, packaging, and machine tooling where repeatable motion, stable torque, and accurate feedback are essential for reliable, high‑performance operation.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268013281514,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-016.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-1fk7042-3bk71-1cg0-simotics-servo-motor","provider":"GTG Hardware","version":"1.0","type":"link"}
