HIOKI recently announced the launch of the Impulse Winding Tester ST4030, which is the company’s first instrument to provide functionality for testing for defects in motor windings. HIOKI provides a ...

The tips and tricks when testing motor-driver ICs on the lab bench can help engineers reduce time spent on evaluating and prototyping motor systems. The first installment of this two-part article ...

A dynamometer is a testing device that helps engineers collect data for various mechanical loading conditions that a motor or engine might encounter in a particular application. Other than testing the ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

Over on his YouTube channel our hacker [Yuchi] is building an STM32 BLDC motor winding machine. This machine is for winding brushless motors because manual winding is highly labor intensive. The ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

In the first installment of this series, "Calculating a practical hotspot safety margin", we discussed how two-parameter thermal models assume that the entire motor, including windings, exhibits one ...
