ABB 3HAC028954-004/03 Servo Motor Product Introduction
Product Description
The ABB 3HAC028954-004/03 servo motor belongs to ABB's dedicated servo drive series for industrial robots and is a core executive component of industrial robot motion control. Adopting high-precision permanent magnet synchronous technology, this motor features fast dynamic response and stable torque output, which can accurately match the motion requirements of robot joints and achieve millisecond-level position, speed, and torque control. Its integrated design incorporates a high-resolution encoder that can real-time feed back the motor's operating status. When combined with ABB's dedicated servo driver, it can effectively reduce operating noise and energy loss, making it suitable for industrial scenarios with strict requirements for motion accuracy and reliability.
Detailed Parameters
- Motor Type: Permanent magnet synchronous servo motor
- Peak Torque: 14.3N·m (short-term overload)
- Rated Voltage: Three-phase AC 230V
- Encoder Type: 17-bit absolute encoder (resolution 131072 ppr)
- Protection Level: IP65 (motor body), IP54 (connector part)
- Cooling Method: Self-cooling (natural ventilation)
- Insulation Class: Class F
- Mounting Method: Flange mounting (compliant with ISO 9409-1 standard, flange size 65mm)
- Operating Temperature Range: -10℃~+40℃ (operation), -20℃~+60℃ (storage)
- Cable Length: 1.5m (standard configuration, including power cable and signal cable)
- Product Number: 3HAC028954-004/03 (version 03, compatible with subsequent upgraded models of the same series)
Product Advantages and Features
- High-Precision Control: Equipped with a 17-bit absolute encoder, the position control accuracy can reach ±0.001°, meeting the high-precision operation requirements of robot assembly, sorting, etc., and avoiding cumulative errors.
- Strong Dynamic Response: Adopting high magnetic density permanent magnets and optimized motor winding design, the start-up response time is ≤10ms, which can quickly adapt to load changes and reduce the overshoot during robot movement.
- High Reliability and Durability: The IP65 protection level can resist dust and splashing liquids, and the Class F insulation level supports operation at 155℃. The motor bearing life reaches 20,000 hours (under rated working conditions), reducing maintenance frequency.
- Energy Efficiency: The motor efficiency level reaches IE3 (international energy efficiency standard), with an efficiency of ≥92% under rated working conditions. Compared with traditional servo motors, energy consumption is reduced by 8%~12%, which can reduce the enterprise's energy costs in long-term use.
- Strong Compatibility: Designed specifically for ABB industrial robot series such as IRB 4600 and IRB 6700, it can be directly adapted to ABB DSQC series servo drivers without additional parameter debugging, simplifying the installation and replacement process.
- Intelligent Monitoring Function: The encoder has a built-in temperature sensor and speed monitoring module, which can real-time feed back data such as motor temperature and speed to the driver. When abnormalities such as overload and overheating occur, it can trigger a protection mechanism to avoid motor damage.
Application Areas
- Industrial Robot Field: As a joint drive motor for ABB medium and heavy-duty robots such as IRB 4600 (load 60kg) and IRB 6700 (load 150kg), it is used in scenarios such as automobile welding, body handling, and component assembly, providing stable power output and precise motion control.
- Automated Production Line: Adapted to the servo axis drive of automated conveyor lines and precision machine tools. For example, in the automobile parts processing line, it controls the robot arm to complete the collaborative movement of workpiece grabbing, positioning, and processing procedures.
- Electronic Manufacturing Industry: Used in semiconductor wafer handling robots and electronic component sorting equipment. With high-precision control capabilities, it realizes the precise picking and placing of tiny components and avoids component damage.
- Logistics and Warehousing Automation: In the drive system of stackers and AGVs (Automated Guided Vehicles) in intelligent warehouses, it provides fast start-stop response and stable torque output, improving the efficiency of cargo handling and positioning accuracy.
- Medical Equipment Field: Adapted to medical robots (such as surgical auxiliary robots and rehabilitation robots), with low-noise operation (noise ≤65dB at rated speed) and high-precision control, meeting the strict requirements of medical scenarios for equipment stability and safety.
Precautions
- Installation Specifications: Before installation, confirm the flatness of the motor flange and the load connection surface (flatness error ≤0.1mm) to avoid uneven force on the motor bearing due to installation deviation, which shortens the service life; the motor cable should be kept away from high-voltage cables (distance ≥30cm) to prevent electromagnetic interference from affecting the encoder signal.
- Wiring Requirements: Power cables and signal cables should be routed separately. The power cable adopts a copper core cable with a cross-sectional area ≥2.5mm², and the signal cable adopts a shielded twisted pair (shielding layer grounding resistance ≤1Ω) to avoid signal interference leading to reduced control accuracy; during wiring, strictly follow the pin definition in the product manual for connection, wrong connection may cause the motor or driver to burn out.
- Operation and Maintenance: Before the first operation, the encoder zero point must be calibrated through ABB servo debugging software (such as DriveStudio) to ensure position control accuracy; check the motor bearing lubrication status regularly (every 6 months). When abnormal noise or vibration occurs, the bearing should be replaced in time (ABB original bearing is recommended, model 6205-2RS); avoid long-term operation of the motor under working conditions exceeding 1.5 times the rated torque to prevent demagnetization of the permanent magnet.
- Environmental Requirements: Avoid using in environments with high humidity (relative humidity ＞90%, no condensation), corrosive gases (such as hydrogen sulfide, chlorine) or excessive dust concentration (＞10mg/m³). If it is necessary to work in harsh environments, additional protective covers (such as stainless steel dust covers) should be installed; the motor should be stored in a dry and ventilated place to avoid direct sunlight. For long-term storage (more than 6 months), it is necessary to power on once a month (no-load operation for 30 minutes) to prevent bearing rust and encoder data loss.
- Safety Protection: Do not touch the rotating parts when the motor is running, and a safety shield must be installed; before maintenance, cut off the driver power supply and wait for the capacitor to discharge completely (at least 5 minutes) to avoid electric shock risk; when replacing the motor, use the same model product, and it is strictly forbidden to replace it with a motor of other brands to prevent driver failure or abnormal robot operation due to mismatched parameters.
