The SUMOT overfluxing inverter
Delivering more power, when needed
Features of the SUMOT device:
- Innovative overfluxing inverter unit incorporating patented dynamic control
- Continuous power gain by pushing back the flux-weakening limits
(up to +20%) - Peak power boost by leveraging overfluxing technology
(up to +100%) - Solution suitable for all voltage/power levels
(e.g., 48V/10kW – 400V/100kW – 800V/300kW) - Greater flexibility in inverter/motor system sizing
- Technology protected by 3 patents
Motor bench tests
Case study
Downsizing of a high-performance traction motor
Resizing by optimization of a SUMOT system – induction traction motor (225 kW). The objective was to minimize its volume and mass while ensuring peak performance with SUMOT.
Multiphysics modeling of the system (electromagnetic, electrical circuit, transient thermal). Consideration of dynamic heating constraints of the machine.
-43% motor volume
-41% motor mass
+50 to 60% system power density
