Product description
The integrated permanent-magnet holding brake of the Siemens 1FT7105-1AC71-1BH1 provides 85 Nm holding torque and operates at 24 V DC. It is a defining feature of this compact SIMOTICS S synchronous servomotor from the 1FT7 series. The motor delivers 38.0 Nm rated torque at 2,000 min⁻¹ and reaches 8.0 kW at its optimum operating point. Standstill torque at 100 K is 50.0 Nm, while maximum torque is 200.0 Nm. This version uses natural cooling without an external fan or water circuit. IP65 protection, vibration grade A and IM B5 mounting with a conventional 1FT6 flange define the basic mechanical arrangement. A plain shaft and rotatable power connector are also part of this order number. The AS24DQI absolute singleturn encoder has 24-bit resolution and transmits feedback through DRIVE-CLiQ and an RJ45 signal connection. A Pt1000 sensor provides continuous motor temperature monitoring. The maximum mechanically permissible speed is 6,000 min⁻¹; the inverter limit is 3,350 min⁻¹. The 50.4 kg net weight refers to this motor configuration. Brake, encoder, shaft and connector arrangement vary across the 1FT7105 family, making the complete order number essential for variant identification. Rotor inertia is 206.00 kgcm².
