alternator 72 Series Shaded pole motor compressor

Product Description: 72 Series Alternator-Driven Shaded Pole Motor Compressor System

Overview
The 72 Series represents an integrated, specialized compressor system uniquely designed for off-grid, mobile, or backup applications. This system pairs a robust 72-frame shaded pole motor with a dedicated alternator power module to create a highly reliable, low-maintenance compression solution. It enables the operation of a standard AC compressor motor from a variable-speed DC or mechanical power source (such as a vehicle engine, small gasoline engine, or battery bank), providing critical cooling or air compression where conventional AC grid power is unavailable or unreliable.

Key Features & Advantages

• Off-Grid & Mobile Power Compatibility: The integrated alternator converts variable mechanical input (e.g., from a pulley driven by an engine) or DC input into the stable single-phase AC power required by the shaded pole motor. This enables compressor operation directly from trucks, boats, remote generators, or solar/battery systems.

• Inherent Motor Simplicity & Reliability: The core compressor drive uses a 72-frame shaded pole induction motor—a technology prized for its lack of brushes, capacitors, or centrifugal switches. This ensures exceptional durability, tolerance to voltage fluctuations from the alternator, and minimal failure points in challenging environments.

• Robust System Integration: The alternator and motor are engineered as a matched set or modular unit. The alternator is designed for continuous duty, with voltage regulation circuits that provide clean, motor-friendly AC output, protecting the compressor motor from under/over-voltage damage.

• High Starting Torque Assistance: The system design often incorporates soft-start capabilities or utilizes the inherent high locked-rotor torque of the shaded pole motor, allowing it to start the compressor against head pressure even with the fluctuating power profile of an alternator source.

• Compact & Vibration-Resistant Design: Built for mobile environments, the entire assembly features rugged construction, secure mounting points, and components resistant to vibration, moisture, and wide temperature ranges.

• Low Maintenance & Serviceability: Both the shaded pole motor and the brushless alternator design require minimal routine maintenance. The system is designed for easy access to key components for service in the field.

Typical System Specifications

• Compressor Motor: 72 Frame, Single-Phase AC Shaded Pole Induction Motor.

• Power Source Input to Alternator:

• Mechanical: 12V or 24V vehicle-style pulley drive (e.g., 1/2" keyed shaft).

• Electrical: 12VDC or 24VDC battery input.

• Alternator Output: Stable Single-Phase AC (e.g., 115VAC, 60Hz or 230VAC, 50Hz), optimized for motor load.

• Compressor Application: Typically for low to medium capacity refrigeration or air compression.

• Typical Cooling Duty: Mobile refrigeration units, emergency backup cooling for telecommunications, specialized transport containers.

• Protection Features: Integrated circuit breakers, over-voltage protection, and thermal cut-offs for both the alternator and motor.

Primary Applications
This hybrid system is engineered for scenarios where compression is needed independent of the electrical grid:

• Mobile Refrigeration: Truck & van refrigeration units (for food, pharmaceuticals), ambulance medical storage compartments.

• Emergency & Backup Systems: Cooling for mobile command centers, emergency response equipment, backup battery room cooling.

• Marine & RV: Refrigeration systems on boats and recreational vehicles.

• Remote & Rural Applications: Off-grid vaccine storage, remote site accommodation cooling.

• Specialized Military & Field Equipment.

Why Choose the 72 Series Alternator-Driven System?
This system solves a critical engineering challenge: providing reliable, continuous-duty compression power in the absence of stable grid electricity. It combines the rugged, simple heart of a shaded pole motor with the flexible power generation of an alternator. For OEMs building equipment for the mobile, remote, or emergency sectors, it offers a proven, integrated, and self-contained power-to-cooling solution that maximizes uptime and minimizes complexity in the field.

Note: System performance is dependent on the correct sizing of the alternator to the compressor motor's locked-rotor and running current. The input power source (engine RPM, battery capacity) must be capable of supporting the full system load. This is a specialized integrated system, not a standard component assembly.
