Electric Motor

iPSM

Prototype available to order

Ironless Stator Design

Patented air coil design eliminates iron losses and electromagnetic drag losses

Modularity

Modularity brings versatility and cost-efficiency, making the motor more adaptable to evolving needs and requirements

Reduced Material Use

Vaionic iPSM requires no electrical steel and uses significantly lower copper and heavy rare earth content compared to conventional PSMs

Recyclability

Active materials can be easily extracted and reused, further reducing lifecycle CO2 emissions

Possible applications

Thanks to the ironless stator concept, the frequency-dependent iron losses are eliminated. As a result, the machine can be designed without field weakening if required and the torque can be kept almost constant up to the maximum speed.

Gen2 iPSM (1 Stator Module)

Our in-house designed stator ironless PSM is the backbone of our powertrain solutions. The iPSM can be operated with and without field weakening due to the elimination of iron losses.

Use-Case Examples

A/B-Segment BEV

Primary drives

With increasing demand for affordable BEVs, almost every high volume OEM will launch such a vehicle on the market within the next three years.

The cost of the drive system is therefore the most important factor. The iPSM with its low active part weight and low production costs with sufficiently high torque in the simplest design with one stator module is therefore ideally suited for use in this segment.

C-Segment BEV

Secondary drives

Due to the fact that the electrification of traction drives means that an additional axle can be powered with relatively little effort, there are also more and more AWD BEVs in the mid-range segment.

Torque and power requirements are significantly lower compared to the primary drive and can therefore be served very well with iPSM technology.

Genuine Cost-Efficiency & Eco-Desing

From words to action. Vaionic iPSM has been designed with sustainability in mind. Significantly reduced active material usage means not only lower BoM costs, but also production costs.
