Description:
The D061A-22-1210 is a compact brushless servo motor from Kollmorgen’s D Series. Model decode: D061A (61 mm frame, variant A), 22 (high-speed winding), 12 (keyed shaft), 10 (single-turn optical encoder).

Key Specifications:

• Frame Size: 61 mm (approx. 2.4 inches diameter)
• Motor Length: A — Shortest Variant
• Winding Type: 22 — High-Speed Winding
• Shaft: With Keyway, D-Cut, 8 mm Diameter
• Encoder: 10 — Single-Turn Optical, 1024 Lines/Rev (4096 Counts/Rev with ×4 Decoding)
• Rated Continuous Torque: 0.65 Nm
• Peak Torque: 1.95 Nm (3× rated)
• Rated Speed: 4,000 RPM
• Maximum Speed: 6,000 RPM
• Voltage Rating: 48 VDC
• Phase Resistance: ~4.2 Ω
• Phase Inductance: ~1.8 mH
• Thermal Class: B (130°C)
• IP Rating: IP40 (open frame)
• Weight: ~0.45 kg

Structural Characteristics:

• Stator: Laminated silicon steel with concentrated windings
• Rotor: NdFeB Magnets, 4-Pole
• Shaft: Stainless Steel, 8 mm Diameter with Keyway
• Housing: Aluminum Alloy, Black Anodized
• Bearing: Sealed Ball Bearings

Working Principle:
Three-phase brushless commutation. The drive switches phase currents based on rotor position from the encoder (sinusoidal commutation) or Hall sensors (trapezoidal commutation), producing continuous rotary torque.

Advantages:

• Very compact form factor — highest power density in class
• Low voltage operation (48 VDC) for safer installations
• Smooth sinusoidal commutation
• Fast electrical response time: <5 ms

Applicable Industries: Medical devices, laboratory automation, small robotics, semiconductor handling, optical equipment, drone actuators, gimbal systems

Installation Requirements:

• Mount via 4× M4 threaded holes on front flange
• Shaft coupling alignment: maximum 0.03 mm TIR
• Keep encoder cable away from power cables (minimum 100 mm separation)
• Operate at 48 VDC ±10%

Usage Notes:

• Do not exceed 6,000 RPM continuous speed
• Ensure adequate ventilation — motor is naturally convection cooled
• Encoder cable maximum length: 5 m (use differential line driver for longer runs)
