Performance testing for electric motors
Evaluate and optimise the performance of your electric motors
The Emitech Group offers comprehensive performance tests for electric motors, enabling you to measure precisely the key characteristics of your powertrain and validate its behaviour under various operating conditions. These tests are essential for the development, validation, approval or benchmarking of your electric propulsion or drive solutions.

Why carry out performance tests on electric powertrains?
Performance testing aims to :
- Determine the torque and power curve as a function of speed.
- Evaluate the overall efficiency of the motor alone or in a chain with its inverter.
- Check thermal performance at different speeds.
- Characterise the operating limits (speed range, peak torque, maximum temperature, etc.).
- Make comparisons between configurations or technologies.
What sectors are involved in these trials?
Engines for electric and hybrid vehicles
Rail propulsion
Aeronautical propulsion
Industrial, robotic and agricultural drives
Our test methodology
1. Installation and instrumentation
- Mounted on a dynamometer with torque, speed, temperature, voltage and current sensors.
- Can be integrated with customer inverter or Emitech Group power supply.
- Cooling control (air, water, oil, dielectric fluid).
2. Test protocols
- Static characterization test: speed or torque step measurements.
- Dynamic characterization test: load rise, acceleration/deceleration cycles.
- Efficiency measurements over the entire useful operating range.
- Peak torque tests over defined durations.
- Regenerative braking tests (if applicable).
3. Data acquisition and analysis
- Real-time performance display.
- Mapping of operating ranges (efficiency, temperature rise).
- Detailed analysis using AVL Concerto, Matlab, Python and Excel tools as required.
