1FK7 – The Most Compact, Cost-Effective, Synchronous Servomotor

Featuring natural cooling and a rugged, maintenance-free design, the 1FK7 synchronous servo motor is ideal for motion control applications where a final position must be reached very quickly with ultimate precision. High Dynamic models have the ability to speed up and slow down very quickly. With high torques of up to 108 Newton meters and a particularly favorable torque-inertia ratio, the 1FK7 motor achieves a very high dynamic response, which means shortened cycles and less wear on the motor, resulting in decreased machine downtime. Servo motors 1FK7 are available in IP ratings 64 to 67 with a high overload capability (up to 3 times rated torque) and rotatable connectors.

Get One in 21 Days!

Siemens Industry, Inc. has introduced a new service for 1FK7 servomotors. Using a configurable options menu to build exactly the motor required, customers can now place an order for any 1FK7 servomotor and have it drop-shipped in three weeks.
