IV. Structure and Core Features
- High-voltage brushless design
- DC 280 V high-voltage power supply, which features lower current and reduced line losses compared to low-voltage motors, is better suited to the high-power requirements of industrial applications and delivers higher long-term operational efficiency.
- Hollow shaft output structure
- Special hollow‑shaft design allows cables and shafts to pass through, accommodating the unique installation layouts of automated equipment (such as winding machines and rotary worktables).
- Integrated Drive System
- When paired with a dedicated driver, it supports PWM speed control, forward/reverse operation, and closed-loop control, achieving a speed regulation ratio of 1:100 or greater with high control accuracy.
- Low noise, high reliability
- Brushless electronic commutation, with operating noise ≤55 dB and minimal vibration; utilizes rare-earth permanent magnet materials, offering stable performance and strong anti-interference capabilities, making it suitable for continuous industrial operation.
V. Typical Application Scenarios
- Industrial Automation: Winding Machines, Rotary Worktables, and Spindles for Small Machine Tools
- Textile machinery: high-speed spinning machines, knitting equipment
- Packaging equipment: high-speed labeler, slitter
- Medical equipment: precision testing instruments, automated medical devices
VI. Usage and Selection Recommendations
- Drive Matching : Requires a compatible high-voltage DC brushless driver (supports a 280 V DC input and Hall‑effect/encoder feedback); the black unit shown in the diagram is the matching driver.
- Safety Precautions : For the high-voltage version, ensure proper insulation protection to prevent electric shock; wiring and commissioning must be performed by qualified personnel.
- Load matching The motor’s rated power must be at least 1.2 times the load’s required power to prevent prolonged operation under overload conditions.
- Installation method : Standard flange mounting; for hollow‑shaft versions, ensure proper shaft concentricity to prevent vibration.
