It is designed for a 600 V DC link and features IP64 protection with an anthracite finish. At the optimum operating point it delivers 0.8 kW, with a rated speed of 3,000 rpm and rated torque of 2.6 Nm at 1.9 A (stall current 2.2 A), while a maximum torque of 10.5 Nm is possible under higher load; maximum mechanical speed is 9,000 rpm and inverter speed up to 6,500 rpm. The holding brake operates at DC 24 V (±10%) with a 0.5 A coil current, opening time about 70 ms and closing time about 30 ms, providing a holding torque of 4.0 Nm and up to 150 J of braking work. This motor is compatible with standard SIMOTICS drive ecosystems and is well suited for precision positioning, CNC tasks, and automated packaging where reliable torque, braking, and encoder feedback are essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268013543658,"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-1fk7042-5af71-1eh3-3-phase-servo-motor","provider":"GTG Hardware","version":"1.0","type":"link"}
