Electric Motors, Inverters and Electric Drives

Electric Motors Development
According to your wishes, we develop any type of electric motor for electric and hybrid vehicles. You will receive from us a complete comparison of all influencing factors, such as the number of pole pairs or the number of slots and layers in the stator. Our main focus is to develop the electric motors in such a way that they can be produced in large volumes in a fully automated and, above all, cost-effective way.
Our services:
- Electromagnetic design of electric motors
- Calculation of characteristic curves and maps
- Electromagnetic simulation 2D and 3D
- Verification of electric motor design
- Efficiency optimization
- Maximization of continuous power
- Design of rotor, shaft and bearings
- Structural analysis of shaft, bearing and housing
- Thermal simulation of the electric motor
- Design of motor cooling and dimensioning
- Software optimization of drive and control
- Acoustic optimization and NVH analysis (noise, vibration)
- Series design and manufacturing optimization
Electric Motor Consulting
We help you to find out which type of electric motor is the best for your electric vehicle. We provide you with a crystal clear comparison of the influencing factors, such as length, diameter and number of magnets. Since we already know the biggest problems of electric motors, we can help you quickly with “out-of-the-box” solutions within two weeks.
Our services:
- Electric motor selection and comparison
- Create, analyze and derive requirements
- Feasibility studies & concept comparisons
- Cost optimization of rotor and stator
- Industrialization and manufacturing strategy
- Patent research of new electric motor types
- Problem analysis of electric motors and solutions


Inverter Consulting
We do not develop hardware for inverters, but we support you in the selection and optimization of suitable power electronics or an inverter. For this we create requirements, as well as a hardware and software architecture for the inverter, which we derive from the requirements of your electric motor. In order for your electric motor to reach its full performance potential, we develop software functions to maximize efficiency.
Our services:
- Selection and comparison of inverters
- Create and derive requirements
- Create a hardware and software architecture
- Software functions for controlling electric motors
- Functions to process current and position sensors
- Thermal simulation of MOSFETs and IGBTs
- Design and simulation of DC link capacitors
Electric Drive Development
Based on your requirements for the drive system, we determine the optimum combination between gear ratio and the characteristic curve of the electric motor for you. This also includes the selection of the right type of electric motor and its torque characteristic, as the necessary cooling for your drive system.
Our services:
- Selection of electric motor, inverter and gearbox
- Optimization of electric motor and gearbox ratio
- Cost optimization and industrialization
- Requirements analysis of motor, inverter and gearbox
- System architecture of electric drives
- Vibration compensation of electric drives
- Risk analysis of axis drives
- Concept comparison of electric drives
- Patent research of novel axle drives


Electric Vehicle Development
For your electric vehicle, we find the best possible combination of electric drives to achieve maximum range with the smallest possible battery capacity. We analyze for you which power class the electric drive of your hybrid vehicle must have in order to have the highest possible fuel savings at the lowest cost.
Our services:
- Selection of the drive architecture
- Drive cycle simulation of WLTP and NEDC
- Calculation of the characteristic curves of the electric drive
- Selection of the right electric drive
- Maximizing the range of the electric vehicle
- Increasing peak and continuous power
- Requirements analysis for the electric drive
- Linking the vehicle requirements to the drive
- Drive concept comparisons and feasibility studies
- Cost optimization between battery and electric drive
- Drive selection, comparison and benchmarking
