Kollmorgen S71262-NANANA
Product Brief:
The S71262-NANANA is a servo motor from Kollmorgen’s S-Series legacy product line. The “NANANA” suffix indicates a configuration with no special options (N = standard encoder, A = standard winding, N = no brake, A = standard connector, N = no special coating, A = standard shaft). This motor is designed for legacy machine integration where older Kollmorgen drives (如 AKD, AKD-P, AKD-M) are in use. It is a general-purpose frame motor with incremental feedback.

Functional Features:
- Incremental encoder — 2048 pulses/revolution, differential RS422 output
- Shaft-mounted fan — provides forced air cooling at all speeds
- Standard winding — compatible with all Kollmorgen AKD-series drives
- Keyed shaft — standard mechanical connection
- Legacy compatibility — designed to work with older Kollmorgen drives (Goldline, SMC series)
Material Composition:
- Housing: Cast aluminum alloy
- Stator: Grain-oriented silicon steel, 0.35 mm
- Rotor: NdFeB sintered magnets
- Shaft: Hardened carbon steel
- Bearings: Sealed ball bearings (double-shielded)
Structural Features:
- Cylindrical body with mounting flange (4-bolt, 71 mm BCD)
- 14 mm keyed shaft with single lip seal
- M23 connector for encoder (15-pin)
- Screw terminals for U/V/W power connections
- Shaft-mounted cooling fan (plastic, 35 mm diameter)
Operating Principle:
Standard trapezoidal or sinusoidal commutation depending on drive configuration. The servo drive energizes the stator windings in sequence based on encoder position feedback. The permanent magnet rotor produces torque. The shaft-mounted fan ensures adequate cooling at low speeds where natural convection is insufficient.
Advantages:
- Legacy compatibility — drop-in replacement for older Kollmorgen motors
- Shaft-mounted fan — reliable cooling at all speeds including zero speed (with external airflow)
- Robust construction — proven design with long field history
- Wide drive compatibility — works with AKD, AKD-P, AKD-M, and legacy Goldline drives
Applicable Industries:
- Legacy machine upgrades
- Retrofit applications
- General-purpose automation
- Material handling
- Printing equipment
Installation Requirements:
- Mount on 4-bolt flange (71 mm BCD), torque bolts to 5 Nm
- Use flexible coupling, max 0.15 mm misalignment
- Encoder cable: RS422 differential, max 15 m, use shielded twisted pair
- Ensure airflow path is not obstructed — fan requires minimum 10 mm clearance
Usage Notes:
- Homing required after every power cycle (incremental encoder)
- Fan is mounted on shaft — do not remove or modify
- Do not operate above 40°C ambient without derating
- Verify drive parameters match motor ratings before commissioning
