Two-parameter motor models assume that the entire motor exhibits one dynamic temperature. Four-parameter thermal models are just as easy to use, but far more accurate — and better for calculating ...

Increasingly, equipment designers who use dc servomotors find that they need customized motor windings to match specific applications. For example, in a retrofit use, the motor’s envelope and ...

For safe, long-term use of a compressor, the motor winding temperature must be kept below certain limits, in all conditions in which the appliance may operate. For example, compressors from AC ...

Chestnut Ridge, NY. Teledyne LeCroy has introduced a new harmonics calculation option for the MDA800 motor drive analyzer series. This optional software package enhances the standard capabilities of ...

The operation of an electric motor is typically simple and reliable, making it possible to overlook during day-to-day maintenance practices. Having a checklist makes it easy to know exactly what to ...

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 ...

[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its ...
