Test overview

■ Purpose

To conduct tests that meet the requirements of the China Regulatory Test (GB/T)

■ Test contents

Example: Vibration test, temperature load test, humidity test, salt spray test, IP test, motor drive test, etc.
(In addition to the above tests, items such as insulation resistance measurement and charge/discharge confirmation are also included.)

■ Test samples

On-board motors and inverters

■ Test period

Approx. 2 months

■ Vibration test 1

EUT : Motor (410 × 780 × 470 mm, 95 kg including fixture)
Conditions: Sinusoidal vibration test (10 to 500 Hz, 8 h/direction), random vibration test (10 to 2000 Hz, 22 h/direction)
Facilities used: K200/SA24HM/H20

■ Vibration test 2 *Test state images are below

EUT: Inverter (200 × 100 × 50 mm, 10 kg including fixture)
Conditions: Sinusoidal vibration test (10 to 500 Hz, 8 h/direction), random vibration test (10 to 1000 Hz, 8 h/direction)
Facilities used: EMK0622/EH

■Temperature load test/Humidity test

EUT: Motor, inverter (Simultaneous testing)
Conditions: ① -40°C × 2 hours ② 85°C × 2 hours ③ 40°C (90%) x 48 hours

*Insulation resistance measurements are carried out before and after each test.
Facilities used: SMS-21

■ Salt spray test

EUT: Motor, inverter (Simultaneous testing)
Conditions:

① Salt spray: 48 hours at a chamber temperature of 35°C and a salt water concentration of 5%

② Drying: 2 hours at a chamber temperature of 30°C

*Insulation resistance measurements are carried out before and after each test.
Facilities used: CYP-200DZ

■ IP test

EUT: Motors and inverters
Conditions: ① IP5X test: dust test ② IPX4 test: waterproof test

*Insulation resistance measurement is conducted before and after the test.
Explanation: IP is a term indicating the degree of protection against solids and liquids external to electronic and mechanical parts, and the test content is defined according to the number that follows (the higher the number, the higher the level of protection), such as IP5X.
*Conducted by an affiliated contractor.

■ Motor drive test

EUT: motor
Conditions *2-hour endurance: Motor speed 2800 r/min, torque 25 Nm, ambient temperature 55°C
Description: This is a test in which a load is continuously applied to a rotating motor. Motor bench facilities used to apply rotation and load to the motor.

*Conducted by affiliated contractor
