When comparing the attributes of a brushless motor with those of its brush motor equivalent, the most notable difference is the reduction in size and weight for the brushless motor offering the same ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has today started to provide engineering samples of a gate driver [1] IC, "TB9084FTG,” for three-phase ...

Toshiba Electronics Europe GmbH has released two sine-wave PWM drive controllers – TC78B043FNG and TC78B043FTG – for three-phase BLDC motors, which can support surface permanent magnet (SPM) and ...

Innovative Swedish boutique carmaker Koenigsegg has revealed a new 6-phase electric motor for its four-seat Gemera supercar that establishes new benchmarks for power density. The Dark Matter motor ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

Section 430.6(A) of the 2023 NEC instructs electricians to size motor connection conductors based on the allowable ampacity tables in Table 310.16. Electricians constructing 3-phase motor circuits “in ...

Somewhere in most engineering educations, there’s a class on induction motors. Students learn about shaded-pole motors, two-phase and three-phase motors, squirrel cage motors, and DC-excited motors.

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...
