Spin’s laboratory is equipped with a test bench for electric motors capable of detecting the main electro-mechanical characteristics. Spin test bench is modular and flexible: it’s possible to check different fixing methods, motor size and geometries.
In the area of engine characterization, we are able to perform the following tests:
- Measurement of Back EMF
- Inductance measurements
- DC and AC resistor measurements
- Measuring torque and mechanical power
- Realization of efficiency maps
- Thermal characterization (S1, S2, S3)
- Vibroacoustic tests
Available test benches in our laboratory
Test bench for high speed electric motor
A smaller high speed bech is now available, operating up to 20krmp with torque sensing precision up to 1mNm. This bench has been designed for smaller motors and actuators (eg. Small fans, drone motors, model motors…). Such precision and custom fixtures enables us to do precise cogging measurements.

- Torque sensor with 0.05Nm precision
- High speed up to 20krpm
- For small motors and actuators
- Cogging torque tests available
Test bench for medium electric motor
Medium test bench allows you to easily test motors up to 5kW thanks to its standard B5 interface

- For motors up to 5kW
- Wide range measurable torques
- Big range of torques measurable (from 0.1 Nm up to 100Nm)
- Brakes up to 100Nm
- Low to high speed
Test bench for big electric motor
The biggest bench in the lab has been designed for motors up to 100Kw. High torques are available up to 500Nm. Power supply ranges from 100VDC, up to 1kVDC. Liquid cooling is also available and adjustable from 10 to 90°C.The mechanics are highly customizable, and its heavy and rigid structure has been designed for vibration testing with very strict alignment tolerances.

- Motors up to 100Kw
- Torques up to 500Nm
- Power supply ranges from 100VDC, up to 1kVDC
- Liquid cooling is also available and adjustable from 10 to 90°C.
In addition to the possibility of characterizing electric motors, we are able to drive electric motors with power electronics that comply with the following values:
- Voltage range 12 – 800 V DC
- Max current 200 Arms
Any specific requests will be evaluated separately with the customer.
Types of electric motors tested in Spin
- PM brushless (SPM, IPM)
- Asynchronous motors (IM)
- Brushless
- Synchronous wound motors (WRSM)
- Axial flux motors
- Switched reluctance motors (SRM)
- Linear motors and actuators
The electric motor testing service includes the rental of the laboratory for a day.
The laboratory rental includes
- The possibility of witnessing the testing of electric motors in the laboratory (performances, vibration and energy efficiency analyses or other customer request)
- Reporting of collected data
- Technical meeting with expert from R&D department. We suggest and propose any improvements and optimizations to resolve problems that emerged during the test
Upon taking charge of the activity, the exclusive set up of the test bench for the mechanical coupling and motor control part is defined. Spin will approve any equipment/materials necessary for the test, which alternatively the committee has the right to supply according to the indications received.
