Electric Motor Emulator

Testing and development for appropriate control concepts in early stages of development.

The Electric Motor Emulator (KS-EME) enables testing of inverters in an early stage of development, or it can be used as a development platform for corresponding control concepts. The focus of development was achieving maximised dynamic range with a wide performance spectrum. 

Meet the highest demands

The uncompromising use of quality components and a powerful computer architecture allow the highest demands on the simulation of electric machines to be met



• Switching frequency: 10 kHz
• Model update rate: 20 kHz
• Highly dynamic SiC-MosFET output stage
• Modular design
• Machine types FSM, PSM, ASM

Physical Design

Physical Design  of the Electric Motor Emulator

• Transformer for galvanic isolation
• Coupling chokes
• Output contactors can be switches under full load


Machine models

• Non-linear machine model
• Specification of inductances and winding resistances (Ld, Lq, Le, Lf, Lfd, Rs, Rf)
• Parameters can be preset as 3D characteristic diagrams f (id, iq, ie)
• Interpolation at runtime
• Parameters can be changed at runtime (e.g. for mapping thermal effects)

Rotary encoder emulation

Sensor types that can be represented: XMR (AMR/GMR), Sin/Cos, Resolver

Analogue outputs 0–5 V: 10 (z.B. 4 x sin/cos, 2 x Diagnose)

Analogue inputs +/- 10V: 2 (Versorgung/Erregung)

Connection: FC Link (LWL), 24 VDC

Up to 2 rotary encoders can be displayed with one DGE. Phase and offset configurable for each signal.
