Siemens SIMOTICS S Servo Motor with Brake & Absolute Encoder
Siemens SIMOTICS S 1FK7 Servo Motor with Holding Brake
The Siemens 1FK7044-7AF71-1EH2 is a SIMOTICS S synchronous servo motor from the 1FK7 High Dynamic series, offering 4.0 Nm torque, 3000 rpm speed, and 1.1 kW power. It features natural cooling and IM B5 mounting. This model includes a rotatable power/signal connector (270°), an Absolute Encoder ENDAT 2048 P/REV (Encoder A-2048), a plain shaft (tolerance N), and crucially, a holding brake. The degree of protection is IP65, with the flange at IP67. Performance is reduced by 10% due to the absolute encoder.
This servo motor is ideal for applications requiring holding torque when power is off, combined with the precision of an absolute encoder. It is commonly used in vertical axes, robotics, and automated machinery where safety and precise positioning are paramount. The IP65/IP67 rating allows operation in demanding industrial environments.
