Description
Product Name: 1785-L20B/E Allen Bradley Programmable controller
Product details:
Allen-Bradley (Rockwell Automation) provides a comprehensive selection of industrial motors and motor control solutions, often focusing on performance, efficiency, and integration with their automation platforms.
1. Product Details & Parameters (General Examples)
Allen-Bradley motors are available in many types, including AC Induction Motors (general purpose and inverter duty) and Permanent Magnet Motors.
| Parameter Category | Common Range/Feature | Notes |
| Power/HP Range | Typically from sub-fractional to several thousand HP | Depends heavily on the motor series (e.g., fractional HP to 20 Hp for some series) |
| Voltage | $230/460 text{V AC}, 575 text{V AC}$ (Common) | Also available in medium voltage (MV) for larger applications. |
| Speed/RPM | $1800 text{rpm}$ (4-pole), $3600 text{rpm}$ (2-pole), etc. | Available for various synchronous and asynchronous speeds. |
| Enclosure | TEFC (Totally Enclosed Fan Cooled), TENV (Totally Enclosed Non-Ventilated), IP44, IP55 | Varies by environment and application (e.g., wet, food processing). |
| Insulation Class | Typically Class F or Class H materials | Indicates thermal endurance and maximum operating temperature. |
| Materials | Cast Iron, Rolled Steel, Stainless Steel | Chosen for durability, corrosion resistance, and specific industry needs. |
| Torque Rating | CT (Constant Torque) $4:1, 20:1, 1000:1$ | Crucial for inverter-duty motors for low-speed operation. |
2. Product Advantages
- High Efficiency: Many designs meet NEMA Premium Efficient standards, leading to lower energy consumption and operational costs.
- Variable Speed Performance: Motors designed for inverter duty (with high CT ratings) are optimized for use with Allen-Bradley PowerFlex Variable Frequency Drives (VFDs), ensuring smooth, precise speed, and torque control.
- Durability & Reliability: Constructed with robust materials (e.g., cast iron, Class F/H insulation) to withstand demanding industrial environments, thermal, and electrical stresses.
- Integrated Solutions: Seamless integration with Rockwell Automation’s Logix controllers and PowerFlex drives via Embedded EtherNet/IP, simplifying configuration, diagnostics, and machine-level control.
- Safety Options: Compatibility with safety features like Safe Torque-Off (STO), which helps simplify wiring and meet standards like SIL 3 / PLe.
3. Precautions (Important Notes)
- Safety Hazards: Always adhere to safety warnings regarding BURN HAZARD (surfaces may reach dangerous temperatures) and ARC FLASH HAZARD. Wear appropriate Personal Protective Equipment (PPE) and follow all regulatory requirements.
- Installation & Maintenance: Installation, wiring, and maintenance activities must be carried out by suitably trained personnel in accordance with all applicable codes, laws, and standards.
- Hazardous Environments: Specific motors and controls are required for hazardous environments to prevent explosions. Always use properly rated equipment.
- Compatibility: When using motors with VFDs (Variable Frequency Drives) or Soft Starters, ensure the motor is rated for the control method (e.g., inverter duty motor for vector control).
- Documentation: Always refer to the specific User Manuals and Programming Manuals for the motor and its associated control device (e.g., PowerFlex drive or SMC Soft Starter) for detailed wiring and operation instructions.
4. Product Applications
Allen-Bradley motors and controls are used across a vast spectrum of industries and applications, including:
- Pumps: Flow and pressure control in water/wastewater, chemical processing, and HVAC systems.
- Fans: Ventilation, dust collection, and HVAC efficiency control.
- Conveyors: Material handling, logistics, and packaging lines requiring smooth speed control.
- Mixers & Agitators: Food & beverage, chemical production requiring consistent torque.
- General Machinery: Presses, extruders, machine tools, and other OEM equipment.
