UAKB-07BK011

 The UAKB‑07BK011 is a high-performance servo motor manufactured by YASKAWA, widely used in industrial automation scenarios requiring precise position control, such as feeding systems, packaging equipment, machine tools and robotics. As a member of YASKAWA’s UAKB series, this model features a rated power of 7 kW and, when paired with a dedicated reducer, delivers high torque output and rapid response.

Key Technical Specifications

• Rated Power: approx. 7 kW
• Rated Speed: approx. 3000 r/min (varies by selected reduction ratio)
• Rated Torque: approx. 30 Nm (higher torque achievable with reducer)
• Power Supply Voltage: 3-phase 200 V - 240 V (380 V optional)
• Feedback Device: Built-in incremental encoder with common resolution of 500 ppr – 1000 ppr
• Protection Class: IP65 (dustproof and waterproof)
• Mounting Method: Flange or base mounting, compatible with standard reducers (e.g., UAKB‑07BK011‑01)
• Weight: approx. 12 kg (including reducer)

Product Features

1. High Rigidity & High TorqueAdopting a permanent magnet synchronous motor structure, it provides high torque and fast acceleration/deceleration capabilities.
2. Compact & LightweightIts small overall size and light weight facilitate installation in space-constrained equipment.
3. High-Precision ControlEquipped with a built-in high-resolution encoder, it achieves ±0.01° position accuracy when used with YASKAWA servo drives (e.g., Σ‑7 series).
4. Reliable ProtectionWith IP65 protection class, it is suitable for humid or dusty industrial environments.
5. Easy MaintenanceThe modular design allows quick separation of the motor and reducer, enabling convenient inspection and replacement.

Structure & Components

• Motor Body: Permanent magnet synchronous rotor, stator windings and heat sink.
• Reducer: Planetary/cycloidal reduction mechanism (UAKB‑07BK011‑01 is the commonly used model) with reduction ratio ranging from 5 to 30.
• Encoder: Built-in incremental encoder that provides speed and position feedback.
• Flange/Base: Used for mechanical connection, compatible with standard machine tools or conveying systems.
• Terminal Block: Interfaces for 3-phase power supply, encoder signals, brake circuit, etc.

Typical Application Fields

• Packaging Machinery: High-speed feeding, counting and sorting.
• Machine Tools: Spindles or feed axes of CNC lathes and milling machines.
• Automated Assembly Lines: Screw tightening and transfer arms.
• Robotics: Joint drive and end effectors.
• Textile & Printing: Tension control and winding systems.

Installation & Maintenance Guidelines

1. Pre-installation InspectionVerify the matching dimensions of the motor and reducer, flange hole positions and power supply voltage compatibility.
2. Fixing MethodSecurely fasten the flange or base to the frame with bolts and ensure accurate axis alignment.
3. Electrical WiringFollow the wiring diagram of YASKAWA servo drives. Correctly connect the 3-phase power supply, grounding and encoder signals.
4. Lubrication & MaintenanceRegularly fill the reducer with special lubricating oil (every 2000 hours or according to operating conditions) and check the oil level and quality.
5. Heat Dissipation InspectionEnsure no dust accumulation on the heat sink; clean it or install an additional fan if necessary.
6. TroubleshootingUse the diagnostic function of YASKAWA drives to read error codes. Common faults include overcurrent, overheating and encoder signal loss.
7. Regular CalibrationCalibrate the encoder zero point every six months to maintain position accuracy.
