1 How to Select a DC Motor: Coreless and Iron Core Brushed DC Motors (June 2017)

DC motors possess linear relationships that allow for very predictable operation. For instance, if enough voltage is applied across the terminals of a DC motor, the output shaft will spin at a rate proportional to that applied voltage. You can take the ratio of the applied voltage over the rated voltage and multiply that number by the no load speed and get the running speed.

2 Pushing the Envelope(s) (September 2015)

With advances in modern technology reducing demand for envelopes, manufacturers are finding it increasingly hard to justify investment.

3 Various Coil Configurations Used in Coreless Motors (September 2020)

Three-dimensional finite element analysis (FEA) simulation and research from published information is used to compare the features of various coil configurations.

4 Reducing Core Loss of Segmented Laminations (June 2009)

The recent trend toward using segmented laminations as a means to increase slot fill and facilitate automated fabrication of electric machines comes with a penalty of increased core loss at the segment joints.

5 Shielding Sensors (March 2020)

Dust, lubricants, extreme weather. No matter what environment your sensors operate in, there are bound to be elements you have to protect them from. Here's how Heidenhain designs their encoders to specifically meet those challenges.

6 Coupling Connection (August 2017)

Couplings and harsh environment use

7 Planning Ahead (April 2019)

Navigating Clutch/Brake Operation in Harsh Environmental Conditions: Chemicals, saltwater, food particles, heat, dust, and electrical corrosion are just a few of the many issues that can cause clutches and brakes to fail prematurely.
