Gear IC has traction

Allegro Microsystems has launched the industry’s first gear-tooth sensor IC to provide incremental position data for traction motors (writes Nick Flaherty). The ATS17501 provides high-speed switching up to 40 kHz to directly measure rotating ferrous gears up to 30,000 rpm, and provides an incremental encoded output...

Wheel motor test platform

Nissan has developed a test vehicle to evaluate the use of electric motors on each wheel (writes Nick Flaherty). It is based on the Leaf e+ platform, with front and rear motors and what Nissan calls a new chassis control system. New control technology being developed by the company integrates its electric propulsion and four-wheeldrive control technologies...

Going everywhere for testing

BorgWarner has converted an Aerial Nomad all-terrain vehicle to all electric operation to test its electric motor technologies and other electric components from suppliers at the system level (writes Nick Flaherty). It is the first high-voltage, all-electric demonstration vehicle to be developed by the company’s Corporate Advanced Engineering group. The new technologies in the test platform include traction inverters...

Scoping out motors/inverters

The accurate analysis of inverter waveforms without interference from switching noise is a key part of evaluating the motor drive circuit, driving the need for a class of test equipment called a ScopeCorder (writes Nick Flaherty). Between 16 and 18% of the total power in an electric car is consumed as losses in the...
