Using models to develop traction motors

With the advancement of EV components, traction motors, in particular, are expected to exert high product performance in terms of low power consumption, high efficiency, high output, low vibration and noise, small size, and low cost. In addition to the performance of the motor alone, it is also necessary to satisfy the requirements and consistency of the inverters, ECU, gearboxes, etc. at the system level and JMAG contributes to the design and verification of these requirements.
One of the requirements for EV traction motors is to achieve high efficiency throughout the entire traction range of the motor in a limited development period. This type of design requires defining many design variables including dimensions and drive conditions, in addition to selecting a motor type. Furthermore, design exploration that extends over a range of individual design variables as wide as possible should be performed at high-speed. JMAG has actual machine level analysis accuracy required in global design exploration at the early design stage, in detailed design and in virtual prototyping and is capable of processing this sequence of design workflow at high-speed.
