Tech Tips: From desktop simulation to motor drive testing 

By Dr.-Ing. Christoph Hahn, Head of Technical Marketing, Speedgoat GmbH

Designing electric motor controls and testing embedded controllers for motor drives is time-consuming, and tests with rotating components and under high-voltage conditions are potentially dangerous. Testing intelligently using digital twins allows for a safe testing environment that not only prevents equipment damage but also personal injury. Furthermore, it provides a continuous workflow across all test phases within a single platform. Development thus becomes faster and more innovative, and errors can be detected early on. […]

X-Division Spreads Helix e-Propulsion to More Markets & OEMs 

Designers of high-performance products for e-mobility are getting to know the Helix brand, launched in 2022 to spread the electric propulsion technology of Integral Powertrain Ltd of the UK to more automotive and motorcycle OEMs while also positioning into aviation, marine and aerospace markets. From its roots in designing propulsion systems for motorsports, Helix has emerged as an established series manufacturer of the power-dense motors, inverters and e-powertrains that it develops. 

Its hallmark Scaleable Core Technology (SCT) platform has three product levels — stock, configured and custom. But its X-Division, focused on developmental projects in automotive, motorsport, aerospace and marine applications, leads the push into new electric powertrain designs. In two recent projects, Helix has designed a direct drive scaleable aerospace electric propulsion demonstrator and developed a revolutionary 650kW continuous output low-inductance motor for a new hypercar project. Both are based upon the company’s core technology in radial-flux motor topology and specialized inverters. […]

Total Performance In-Line Validation for Electric Vehicle Motors 

The motor of an electric vehicle (EV) must follow a thorough validation process. Improper assembly, insulation or alignment of these parts will damage the motor, rendering the car unusable and becoming a liability. To protect their customers as well as their brand, our client needed to develop a multi-bench validation line for a smarter solution through this shift in electric automotive technology.  […]

Inductive Couplers from Premo Sniff for Problems in EV High-Voltage Systems 

Electric vehicles present unique challenges when it comes to monitoring their high-voltage systems. This is where sniffing applications come in. Sniffing involves the use of inductive couplers to measure the current and voltage signals on high-voltage cables without the need for direct contact with the cables themselves. The non-intrusive method of monitoring can be critical for ensuring the safe and efficient operation of EVs.  […]
