Motor development and manufacturing

Peter Donaldson details the many processes involved in creating new motor systems. As with any sophisticated industrial process, the development of motor systems for e-mobility is a complex and multi-stage endeavour, subject to rapid change under pressure, both to innovate and ramp up to high production volumes.

Going flat out

The CTO of YASA Motors tells Rory Jackson how his axial-flux ‘pancake’ motors originated from a complex algorithm and a simple question Today, Tim Woolmer is the CTO of axial-flux electric-machine manufacturer (and wholly owned Mercedes-Benz subsidiary) YASA Motors, but his initial entry into the world of e-mobility was something of a happy accident.

Coveme electric motor slot and battery spacer insulation for high-voltage applications

With motor voltages in many e-mobility applications effectively doubling from the 400V region to 800V or more, one of the issues that arises is preventing breakdown of the insulation within the motor slots, the key stressor being partial discharges.

bdtronic’s new machine targets the impregnation of windings

bdtronic’s B8650 impregnation machine enhances electrical component manufacturing, targeting the impregnation of windings in rotors, stators and coils used in electric motors.

Deep Insight

Coil windings

Peter Donaldson takes electric machines apart to examine the inner workings of coil windings. At first glance, electric machines are simple. They have one moving part, the rotor, which either rotates in response to an input of electrical energy or puts out an electric current in response to an input of mechanical energy that rotates it.

Nestech takes rapid prototyping of motor cores to a new level

As electrical machine manufacturers strive to squeeze ever more efficiency out of motors and generators, there is a growing need for rapid prototyping to support tests of new core geometries in hardware form to confirm they perform in the way simulations say they should, writes Peter Donaldson.

Why design-for-manufacture could make Traxial axial flux motors go mainstream

Touted as the future of EV propulsion, axial flux motors are more compact, lighter and offer higher power and torque densities than their radial flux counterparts. Until now, they have been exceedingly hard to build but Traxial, a subsidiary of Magnax, is
