Refrigerator Evaporator Fan Motor

Product Specifications

Technical details and manufacturing context for Refrigerator Evaporator Fan Motor

Definition

This component is a compact electric motor specifically designed to power the fan that circulates cold air across the evaporator coils in domestic refrigerators and freezers. It is critical for maintaining uniform temperature distribution throughout the appliance's storage compartments. The motor operates continuously during cooling cycles to ensure efficient heat exchange and prevent frost buildup. It must balance reliable performance with minimal noise and vibration in household environments.

Typical specifications include a rated voltage of 12 V AC, power consumption between 2 and 5 W, and a rated speed of 2500–3500 RPM. The shaft diameter is 4–6 mm, and the motor weighs 0.3–0.8 kg. It is designed for an operating temperature range of -30 to 70 °C and a non-condensing humidity range of 0–95% RH. The IP rating is IP54, indicating protection against dust and water splashes. The insulation class is B per IEC 60085, and the noise level is 25–35 dB(A) at 1 meter, measured according to ISO 3744. The motor uses ball bearings for longer life and provides airflow of 50–150 m³/h.

Materials typically include copper winding wire, laminated silicon steel, PBT plastic housing, and a stainless steel shaft. These materials are selected for durability and performance in cold, humid environments.

For procurement, verify model-specific values and standards with the legal manufacturer or supplier. The listed parameters are reference ranges and must be confirmed for the actual application. Ensure that the motor's electrical and mechanical interfaces match the refrigerator's design, and check compliance with relevant safety and performance standards.

Working Principle

The motor converts electrical energy into rotational mechanical energy through electromagnetic induction. When AC voltage is applied, current flows through the copper windings, creating a rotating magnetic field. This field interacts with the laminated silicon steel rotor, causing it to spin. The rotor is connected to a stainless steel shaft, which drives the fan blade assembly. The spinning blades create directed airflow across the evaporator coils, facilitating heat exchange. The motor's design minimizes noise and vibration, and its ball bearings support smooth rotation. The speed and torque are matched to the fan load to ensure efficient air circulation.
