Test benches

The test bench presented on this page, are part of the platform “Conversion” at Ampère Lab.

Synchronous machines benches available at Ampère Lab

Our aim at Ampère Lab is to have synchronous machines test benches that meet the trend on the topic following classification proposed in (Moriomoto2007) :

Surface Permanent Magnet Synchronous Motor (SPMSM)

SPMSM are widely used in the industry, thanks to their high power density, high efficiency, ease to manufacture and compact structure. To fully take advantage of the intrinsic characteristics of SPMSMs, vector control is usually implemented. When high speed performance is required, the aforementioned control technique is augmented using ad hoc methods such as flux weakening (FW).

Some current research issues:

Technical specifications:

Nominal characteristics
Nominal Power 170 W
Nominal Speed 6000 rpm
Nominal Torque 0.27 Nm
Nominal current 7.1 A
Nominal Voltage 24 V (Y)
Load motor Identical
Torque meter Magtrol TM304

Interior Permanent Magnet Synchronous Motor (SPMSM)

Midway between SPMSM and SynRM, IPMSM benefits from both magnet torque and reluctance torque. Increasing ratio between d and q inductance also increase the field weakening capacity of such motors. IPMSM are good candidates for mobility application.

Technical specifications:

Nominal characteristics
Nominal Power 7.5kW
Nominal Speed 3000 rpm
Nominal Torque 24 Nm
Nominal current 20 A
Nominal Voltage 310 V (Y)
Load motor Identical
Torque meter Magtrol TM304

Synchronous Reluctance Machine

Synchronous reluctance machines have seen renewed interest in recent years due to the absence of permanent magnets (usually neodymium magnets) and the consequent reduction in the use of rare earths in these electrical machines.

Technical specifications:

Nominal characteristics
Nominal Power 1,5 kW
Nominal Speed 1500 rpm
Nominal Torque 9,5 Nm
Nominal current 4,1 A
Nominal Voltage 400 V (Y)
Load motor PMSM Leroy-Somer 95UMC300HAAAA

Axial Flux Permanent Magnet Generator

Small scale (< 20 kW) Wind Energy Conversion Systems (WECSs) are mainly used for rural electrification in remote areas or residential behind-the-meter grid connected application. Locally Manufactured Small Wind Turbines (LMSWTs) are identified as an adequate technology for sustainable rural electrification.
