Overview

ISO 21782-6:2019 - "Electrically propelled road vehicles - Test specification for electric propulsion components - Part 6: Operating load testing of motor and inverter" specifies operating-load tests and acceptance criteria for motors and inverters designed as a voltage class B electric propulsion system for electrically propelled road vehicles. The standard defines endurance and verification tests that evaluate mechanical and electrical robustness under repeated high-load and transient conditions, and it links to general definitions and test conditions in ISO 21782-1:2019.

Key topics and technical requirements

Scope and linkage

Applies to motor and inverter components of voltage class B propulsion systems.
Normative references include ISO 21782-1 for general test conditions and definitions.

Motor operation endurance tests

High acceleration/deceleration endurance test: evaluates fatigue on bearings, end rings, shaft key, rotor fixture, rotor, and position sensor by repeating intermittent maximum speed cycles. Cycle counts are ranked (C → S) - e.g., C = 100 000 cycles (bidirectional), S = 500 000 (bidirectional); single-direction rankings are higher (C = 200 000, S = 1 000 000). Pre/post-energizing measurements and optional disassembly criteria (back-EMF ±5%, position sensor ±5° electrical, torque ±5%) are specified.
Maximum torque endurance test: stresses components under intermittent maximum torque at constant speed. Ranks and cycle counts are provided (C = 300 000 up to S = 2 000 000). Temperature control to saturation during permissible continuous load is required.

Inverter operation endurance tests

Cyclic test: verifies inverter endurance under repeated load transients (details and test parameters defined in the standard).

Rotor breakdown strength verification

Spin test and other verification methods to confirm rotor mechanical integrity.

Measurements & acceptance criteria

Key measurable criteria include back-EMF, torque–speed characteristics, position sensor waveform, vibration, and post-test physical inspection (bearings, end ring, shaft key, rotor, adhesives).

Test reporting

Test report contents and an informative annex template are included.

Practical applications and users

Who uses it: OEMs, propulsion component suppliers, independent test laboratories, validation and reliability engineers, and procurement teams specifying component durability.

Typical uses: component qualification, supplier benchmarking, durability ranking, validation during design iteration, and contractual verification for motor and inverter acceptance.
