Kollmorgen NTTRB1-5301-13-A-03-1

Product Name: Kollmorgen NTTRB1 Series Frameless DC Torque Motor

Product Series: NTTRB1 Frameless Torque Motor

Product Type: Frameless Brushless DC Torque Motor

Model Number: NTTRB1-5301-13-A-03-1

Detailed content

Continuous Torque53 Nm (5301 = 53 Nm continuous)

Outer Diameter: 130 mm (13 = 130 mm OD)

Stack Length: Approximately 13 mm (03 = stack length code)

Motor Type: Ironless Core DC Torque Motor

Construction: Frameless design, no housing, no bearings, no shaft. Requires customer-supplied mechanical integration.

Winding Configuration: Custom wound per specification code 03-1

Electrical Characteristics:

  • Voltage Rating: Custom per winding (typically 24V to 480V DC range)
  • Resistance: Low resistance ironless winding for high efficiency
  • Thermal Time Constant: Short due to ironless construction

Material Composition:

  • Stator: Copper windings on ironless core
  • Rotor: Rare-earth permanent magnets (NdFeB)
  • Housing: None — frameless integration

Performance Features:

  • Zero Cogging Torque due to ironless core design
  • Smooth Torque Output across full rotation
  • High Torque-to-Inertia Ratio
  • Excellent Thermal Dissipation via direct mounting to customer heat sink

Operating Principle: Brushless DC commutation. Torque is proportional to current. Rotor position sensed via Hall sensors or external encoder for commutation.

Advantages:

  • Ultra-smooth motion with zero cogging
  • Compact form factor for direct-drive applications
  • High dynamic response
  • Long operational life due to brushless design

Applicable Industries: Semiconductor manufacturing, optical equipment, radar systems, gimbal systems, precision pointing systems, medical imaging equipment.

Installation Requirements:

  • Must be press-fit or bonded into customer mechanical structure
  • Requires external bearing support
  • Requires external encoder for position feedback (if not using Hall sensors only)
  • Thermal path must be provided to external heat sink

Precautions:

  • Do not exceed rated continuous current
  • Ensure adequate thermal management
  • Handle with ESD precautions due to permanent magnet rotor
