Kollmorgen 606-S60600
Product Family: 606 Series DC Servo Motor
Product Overview:
The 606-S60600 is a brush-type DC servo motor from Kollmorgen’s legacy 606 product line. The “S60600” suffix designates the specific winding and mechanical configuration. This motor uses brush commutation with an integrated tachometer for velocity feedback.

Material Composition:
- Housing: Aluminum alloy (anodized)
- Shaft: Hardened stainless steel
- Brushes: Carbon-graphite composite
- Magnets: Samarium Cobalt (SmCo) — high temperature stability
- Windings: Class H insulation (180°C rated)
Structural Features:
- Compact cylindrical body with rear-mounted connector
- Integral tachometer mounted on rear end bell
- Precision ball bearings (front and rear)
- Keyed shaft for positive coupling
Working Principle:
DC current flows through the armature windings via carbon brushes and a mechanical commutator. The interaction between the armature current and the permanent magnetic field produces torque. The tachometer generates a voltage proportional to shaft speed, providing closed-loop velocity feedback.
Advantages:
- Simple drive electronics required (brush commutation)
- High torque-to-inertia ratio
- Cost-effective for moderate-performance applications
- SmCo magnets provide stable performance at elevated temperatures
Applicable Industries:
Legacy machine tools, lab equipment, valve actuators, small robotic joints, antenna positioning, medical device actuators
Installation Requirements:
- Mount with flexible coupling to minimize shaft loading
- Align shaft concentricity within 0.05 mm
- Ensure adequate ventilation — forced air cooling recommended at continuous rating
- Brush life: approximately 2000 hours at rated load — plan for replacement
Usage Notes:
- Brush wear is normal — monitor tachometer signal for commutation noise
- Do not operate without tachometer feedback in closed-loop mode
- Replace brushes when sparking exceeds 2 mm at commutator surface
- Maximum ambient temperature: 40°C continuous, 55°C intermittent
