Why carry out electric motor endurance tests?
Endurance tests are used to :
- Test the motor's resistance over extended operating cycles.
- Check performance stability (torque, efficiency, temperature).
- Identify the phenomena of ageing, wear or electrical and mechanical degradation.
- Validate the design and sizing of the cooling system.
- Prepare for certification or series production.
What sectors are involved in these trials?
Electric and hybrid vehicles
Rail
Aerospace and defence
Energy and industrial applications
Our technical resources for endurance testing
The Emitech Group has motorised and instrumented test benches for long-term endurance campaigns:
- Tests under constant or variable load.
- Programmed thermal and mechanical cycling.
- Continuous monitoring of physical quantities: current, voltage, temperature, speed, vibration.
- Operation for up to several thousand hours.
Simulatable test conditions
- Controlled ambient temperature (-30°C to +90°C).
- Dry, humid or air-conditioned environments.
- Simulation of repeated starts, load increases, stop & start cycles.
- Tests with air, liquid or mixed cooling.
What parameters are measured
- Changing motor efficiency.
- Heating of windings, magnets and sensors.
- Insulation resistance.
- Leakage currents.
- Mechanical vibration and noise.
Possible integrations
- Endurance tests can be combined with :
- Climatic tests (temperature, humidity).
- Vibration tests.
- Electrical tests (insulation, overvoltage, short-circuits).
- EMC tests.
