Applications and Features
1. Function: Circulates hot air within the reflow oven chamber, forcing hot air convection to ensure uniform PCB surface temperature; a key spare component for reflow oven temperature control.
2. High Temperature Resistance: H-class insulation, capable of continuous operation in the high-temperature environment of the oven; built-in thermal protection, automatically shutting off power in case of overheating.
3. Structure: Integrated flange + extended shaft + aluminum impeller; direct replacement of the entire set for easy assembly and disassembly; original Nidec motors are Heller original parts.
Common Replacement and Spare Parts Information
– Heller Original Part Numbers: 594768 / 595108 (Nidec motors in the same series, but the last two digits differ; check the label)
– Vulnerabilities: High-temperature bearing wear, capacitor degradation, coil aging; Fault symptoms: Abnormal noise, insufficient speed, increased temperature difference in the heating zone, failure to start.
– Distinguishing features: The Heller MK5 motor has a similar appearance, but its power, impeller size, and mounting hole positions are different. The MK7 cannot be directly replaced by the MK5 motor.
