2018 Renault ZOE uses new electric motor

Renault’s 2018 ZOE uses a brand new electric motor. The R110 motor is derived from the R90 motor, to which it is identical in both size and weight, but offers increased output of 80 kW. Renault attributed the extra output to a combination of electrical machine- and power electronics-related innovations, but provided no further details…. Read more »

Toyota develops new magnet cutting the use of rare earth element neodymium in electric motors

Scientists at Toyota have developed a new heat-resistant magnet that uses “significantly less” neodymium, a rare earth element commonly used in magnets for electric motors. Neodymium is critical for maintaining magnetization at high temperatures. The amount of neodymium in Toyota’s magnets has been reduced by up to 50 percent, partially replaced with lower-priced rare earths… Read more »

Tesla’s top motor engineer talks about designing a permanent magnet machine for Model 3

Most mainstream EVs from major automakers have used some form of permanent magnet traction motor technology, with two high-profile exceptions: Tesla’s Model S and Model X both use induction motor technology. Internet engineering forums are full of compelling arguments for using both technologies in vehicles, as well as loads of speculation on what drove Tesla… Read more »

MDL’s new Motor-CAD v11 motor design software

Motor-CAD is aimed at motor designers, and is designed to perform quick and easy electromagnetic and thermal performance tests on electric machine designs. Motor-CAD is composed of three main modules: EMag, Therm, and Lab. The EMag module… Read more »

AVID Technology ships first EVO electric motors, secures £50 million in new orders

UK-based AVID Technology has begun shipping its EVO electric motors. AVID took over the design, manufacture and distribution of EVO motors from GKN Hybrid Power last year, and has now completely transferred production to its plant in Cramlington, Northumberland. Since the start of the year, AVID has secured over £50 million in new orders for… Read more »

A closer look at energy consumption in EVs

When it comes to factors that affect energy consumption in EVs, the big kahunas are weight and wind resistance (aka CdA), but there are other factors that can have a surprisingly outsized effect and that tend to be overlooked, such as the use of climate control (AC, of course, but especially heat). Conversely, one factor… Read more »

Groupe PSA and Nidec form JV for automotive traction motors

Groupe PSA, owner of the Peugeot, Citroën, DS, Opel and Vauxhall brands, and Nidec Leroy-Somer, a French manufacturer of small precision motors, plan to form a joint venture to develop a range of traction motors for electrified vehicles. The 50/50 JV will receive an initial investment of €220 million ($262 million). The main components of… Read more »

Finnish manufacturer Visedo has unveiled a new electric motor design optimized for the e-bus market. Visedo says its new S-model PowerDRUM has achieved a 10% increase in power output, as well as better cooling. The company has upgraded its entire PowerDRUM line, which includes motors in 4 different sizes, ranging from 50 to 343 kW…. Read more »

Making a motor: Many automakers rely heavily on third party motor-winding experts like Odawara Engineering

Electric motors are everywhere: in household appliances, in hand tools, in buildings, in consumer electronics, and increasingly in automobiles. Motors are used in windshield wipers, power windows, throttle controllers, and, more and more, in the drivetrains of electrified vehicles. Electric motors abound, and Odawara Engineering knows how to make them. Charged spoke with Odawara’s Chris… Read more »

A closer look at wire in EVs

Wire is not the most glamorous of components, but it is the enabler of our modern society – especially of our even more modern mode of transport, the EV – and a surprising amount of technology and engineering goes into making, selecting and using wire. How wire is made The modern method of manufacturing copper… Read more »
