Compact motor for low power applications with natural cooling
The 1FK7 motors are very compact, permanent-magnet synchronous motors that are available in the High Dynamic, High Inertia and Compact versions. They have a high overload capability and rotatable connectors.
1FK7 CT Compact – for universal applications
1FK7 Compact motors offer high power density within extremely compact dimensions. Because of their short overall length, they are simply predestined to be installed in tight spaces. Their compactness makes them the standard motor used in torque ranges of between 0.18 and 48 Nm. They make Motion
Control axes exceptionally dynamic, thanks to their high overload capability. The motor spectrum comprises 22 types with 7 shaft heights and rated speeds up to 6000 rpm.
1FK7 HD High Dynamic – for maximum acceleration
1FK7 High Dynamic motors are characterized in addition to their high overload capacity by their low moment of inertia. Thereby, they reach an extremely high acceleration capacity. 1FK7 HD motors are especially suited to applications with very short cycle times, e.g. in packaging machines. The spectrum includes 11 types with a torque range from 1.3 to 28 Nm and rated speeds up to 6000 rpm.
1FK7 HI High Inertia – for rugged closed-loop control
1FK7 High Inertia motors, as compared with the Compact version, have a higher rotor moment of inertia. For high load inertias, the increased rotor moment of inertia provides for a comfortable control response. The controller default settings are sufficient to ensure a good surface quality on the workpiece when the motor is employed on feed axes with high or variable load inertia. The motor range includes 6 types with 3 shaft heights with torques from 3 to 20 Nm and rated speeds up to 6000 rpm.
