IEC 61855 Hair Dryer Air Blockage Test Machine For Airflow Blockage And Motor Stall Testing
Advanced testing equipment with PLC intelligent control and 7-inch HMI touch screen for 50% and 100% adjustable airflow blockage testing of hair dryers and styling appliances.
Product Overview
The Air Blockage Test Machine is engineered for comprehensive airflow blockage and motor stall testing of hair dryers and hot-air hair styling appliances. By simulating partial and complete airflow obstruction scenarios, the system rigorously evaluates thermal safety performance, motor overload protection capabilities, and over-temperature response mechanisms to ensure full compliance with international safety standards including GB/T 23106-2024, QB/T 1876-2023, and IEC 61855:2022.
Applicable Products
Handheld hair dryers
Heated hair styling appliances
Testing Purpose & Methodology
Testing Objectives
Air blockage performance evaluation (50% / 100% obstruction)
Motor stall overload protection verification
Temperature rise assessment of critical components
Safety device response validation
Testing Principles
Motor Stall Simulation
When the motor rotor is mechanically locked:
Motor current increases to 3-8 times normal operating values
System evaluates motor burnout risk and winding conditions
Assesses accuracy and response time of thermal protection devices
Airflow Blockage Simulation
Through mechanical blockage of air inlet/outlet:
Simulates 50% and 100% airflow blockage conditions
Evaluates surface temperature rise at critical locations
Tests effectiveness of thermal cut-off safety devices
