A small 0.75 horsepower, 4-pole, 460 V, Class F AC motor (Figure 1) was chosen for the model rewind. This motor was selected as it is compact in size and has lightweight dimensions to allow easy ...

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 ...

Since it is essential to design an aircraft engine nozzle to achieve IR signature suppression, an S-shaped nozzle (double serpentine nozzle) is applied so that the high temperature part of the engine ...

Electrical angle alignment of brushless dc (BLDC) motors is the process of determining how to apply electric current to the motor. In essence, it is determining where the magnets are with respect to ...

(Nanowerk News) Lappeenranta University of Technology (LUT) in Finland has constructed the world’s first prototype electrical motor using carbon nanotube yarn in the motor windings. The new technology ...

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 ...

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 ...

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 ...

Combined with productivity and associated reliability costs, a motor circuit analysis program can justify itself immediately. In recent years methods for controlling energy costs have evolved from a ...
