Complete Model Guide for Siemens 1FK7 Series Compact Synchronous Servo Motors

1. Series Overview & Naming Rules

The Siemens 1FK7 series (SIMOTICS S1FK7) are permanent magnet synchronous servo motors, divided into three types: ط م (مدمج), عالية الدقة (High Dynamic), HI (High Inertia).

The following focuses on the full CT Compact models (selfcooled IC410, IMB5 mounting), available in Generation 1 (5A series) and Generation 2 (2A series), with Generation 2 as the current mainstream.

5. Replacement Model Guide
6. Generation replacement: Gen1 5A series → Gen2 2A series (على سبيل المثال, 1FK70815AZ91 → 1FK70812AZ91), mounting dimensions and electrical interfaces remain compatible
7. Power upgrade: Same frame size, different length codes (على سبيل المثال, 081 → 083, power from 12 kW to 16 كيلوواط)
8. Function upgrade: Standard → KUKA dedicated (requires 1ZZ9 mechanical interface and resolver)
9. إرشادات الاختيار
10. Power matching: Calculate required rated power and torque based on load; 20% margin recommended
11. Speed requirement: Confirm maximum speed meets application (معيار 6000 دورة في الدقيقة, some up to 8000 دورة في الدقيقة)
12. Encoder selection: Absolute / تزايدي / resolver based on control system
13. Protection rating: معيار IP65, shaft IP67, مناسبة للبيئات الصناعية القاسية
14. Custom requirements: For KUKA robots and special applications, select dedicated models with 1ZZ9 suffix and Z code
