Overview
The 72 Series is an advanced, application-specific drive inverter engineered to integrate seamlessly with 72-frame shaded pole motors in compressor systems. This innovative solution transforms a simple fixed-speed shaded pole motor into a variable-speed drive, enabling precise control over compressor output, significant energy savings, and enhanced system performance for refrigeration, air conditioning, and specialized cooling applications.
Key Features & Advantages
Enables Variable Speed Control: Unlocks the ability to precisely modulate the speed (and thus the output) of a traditionally fixed-speed shaded pole motor compressor. This allows the system to match cooling capacity exactly to the real-time thermal load, eliminating the inefficient on/off cycling of conventional systems.
Significant Energy Efficiency Gains: By avoiding frequent high-current startups and allowing the compressor to run at its most efficient partial-load speeds, this inverter can reduce overall system energy consumption by 20-40% compared to standard fixed-speed shaded pole compressor operation.
Soft Start & Smooth Operation: Provides a controlled, ramped voltage/frequency start for the motor. This drastically reduces inrush current (by up to 80%), minimizes mechanical stress on pistons and bearings, and extends the overall lifespan of the compressor.
Optimized for Shaded Pole Motor Characteristics: The inverter's control algorithms are specifically tuned for the unique torque-speed profile and starting characteristics of shaded pole motors, ensuring reliable start-up under pressure and stable operation across the entire speed range.
Integrated Protection & Diagnostics: Features comprehensive protection against over-current, over-voltage, under-voltage, motor overload, and over-temperature. Provides fault codes and operational data (speed, current, run time) for easy system monitoring and troubleshooting.
Compact & Environmentally Robust Design: The 72 Series housing is designed to withstand the challenging environments near compressors, with protection against vibration, moisture, and wide ambient temperature ranges. Its compact form factor allows for flexible mounting inside or adjacent to the compressor unit.
Easy Retrofit & OEM Integration: Designed for both new installations and as a retrofit solution to upgrade existing 72-frame shaded pole compressor systems. Features plug-and-play compatible connectors and straightforward parameterization.
Typical Specifications
Compatible Motor: 72 Frame Single-Phase AC Shaded Pole Motors (for compressors).
Input Power: Single-Phase AC, 100-120V / 200-240V, 50/60 Hz.
Output to Motor: Variable Frequency, Variable Voltage, Single-Phase AC.
Output Frequency Range: Typically 30 Hz to 70 Hz (adjustable), allowing motor speed variation from approximately 50% to 120% of base speed.
Control Interface: Simple analog (0-10V / 4-20mA) or digital (PWM) input for speed command from a thermostat or system controller. Status relay outputs.
Protection Rating: IP20 (enclosed) or higher for protected installations.
Communication: Optional RS-485 Modbus RTU for advanced system integration and data logging.
Key Protections: Motor Overload, Short Circuit, Over/Under Voltage, Overheating.
Application Benefits for Compressor Systems
Precise Temperature Control: Maintains tighter temperature bands by modulating cooling capacity, improving product preservation in refrigeration.
Reduced Mechanical Wear: Eliminates the damaging electrical and mechanical shocks of direct-on-line starting.
Lower Peak Electrical Demand: Reduces startup current, which can lower utility demand charges and allow operation on smaller generators or circuits.
Quieter System Operation: Operates the compressor at lower, quieter speeds during partial load conditions.
Ideal For
Retrofitting existing refrigeration compressors, ice makers, or dehumidifiers using 72-frame shaded pole motors.
New OEM designs for small refrigerators, beverage coolers, medical storage devices, and residential dehumidifiers where variable capacity and efficiency are desired.
Specialized cooling systems requiring precise thermal management.
Why Choose the 72 Series Drive Inverter?
This inverter is a game-changing upgrade for shaded pole motor compressor systems. It bridges the gap between the simplicity and low cost of a shaded pole motor and the efficiency and control of a fully variable-speed system. By investing in this drive, you are not just adding a controller—you are fundamentally enhancing system intelligence, slashing energy costs, and extending equipment life, delivering a rapid return on investment and a superior end-user experience.
Note: Successful application requires verifying the compatibility of the specific shaded pole motor with variable frequency operation, as not all are designed for it. Proper thermal management of both the motor and inverter is essential. Consult the technical manual for detailed wiring, parameter settings, and derating guidelines.
