ISO 21782‑5 is part five of the multi-series standard on test specification for electric propulsion components, operating load testing of the motor system.
ISO 21782‑5 specifies operating load tests and test criteria for the motor system designed as a voltage class B electric propulsion system for electrically propelled road vehicles.
ISO 21782‑5 on test specification for electric propulsion components-operating load testing of the motor system is applicable to:
ISO 21782‑5 provides test to evaluate and rank the strength for the components – motor shaft key, rotor fixture, shaft tightening part, stator fixtures, power semiconductor chip, and DC bus capacitor – which are affected by mechanical or electrical fatigue. This test will help you increase the durability of the motor system.
ISO 21782‑5 gives test to ensure that the voltage applied to motor input terminal is below the withstand voltage specified by the motor manufacturer in consideration of temperature, humidity, barometric pressure and durability.
ISO 21782‑5 ensures that no control failure occurs in the motor system within the required speed range under operating conditions that exceed the maximum operating speed of the motor system.
