Performance testing and tuning of electric motors
Evaluate, calibrate and optimise your electric motors
The Emitech Group offers a comprehensive range of performance and tuning services for electric motors, covering the precise measurement of key characteristics, the calibration of control algorithms and functional validation in simulated or real-world environments.
These tests are essential for the development, certification, benchmarking or mass production of your electric propulsion or drive solutions.
Why carry out performance and tuning tests on electric powertrains?
- Determine the torque and power curves as a function of speed.
- Evaluate the overall efficiency of the motor, either on its own or in combination with its inverter.
- Precisely calibrate the control algorithms (FOC, DTC, vector control, V/f, BLDC, etc.).
- Optimise start-up, inrush current management and speed transitions.
- Verify thermal performance and dynamic behaviour (acceleration, regenerative braking, torque reversal).
- Characterise operating limits (speed range, peak torque, maximum temperature).
- Prepare for type approval or series production.
What sectors are involved in these trials?
Engines for electric and hybrid vehicles
Rail propulsion
Aeronautical propulsion
Industrial, robotic and agricultural drives
Our methodology
1. Installation, instrumentation and characterisation
- Mounting on a dynamometer bench with torque, speed, temperature, voltage and current sensors.
- Determination of electromechanical characteristics (inductance, resistance, rated torque).
- Can be integrated with the customer’s inverter or an Emitech Group power supply.
2. Performance measurements
- Static characterisation tests at different speed or torque levels.
- Dynamic tests: load ramp-up, acceleration/deceleration cycles.
- Efficiency measurements across the entire operating range.
- Mapping of operating ranges (efficiency, heating).
- Peak torque and regenerative braking tests.
3. Control system tuning
- Adjustment of control algorithms (FOC, sinusoidal, BLDC, etc.).
- Tuning of current, speed and position loops.
- Optimisation of start-up and management of speed transitions.

4. Thermal and energy validation
- Simulation of real operating profiles.
- Monitoring of heating (windings, magnets, bearings).
- Analysis of overall motor + inverter efficiency.
5. Tuning in specific environments
- Integration into a climate, vibration or EMC test campaign.
- Verification of performance stability under external stresses.
What parameters are measured
