California Linear Devices, Carlsbad, Calif., uses high-response windings to gain tight control and accuracy in their motors. They use series windings rather than a series-parallel wound coil. This ...

It ‘s worth noting that back EMF plays a critical role as a natural current limiter during normal motor operation. When motor ...

To achieve EV potential by squeezing more functionality into a given volume, and delivering value at a compelling price point ...

SAIC Motor has been granted a patent for an innovative electric motor winding structure. This design features a multi-phase winding arrangement using hairpin conductors in a grooved iron core, ...

Not all inverter-duty motors are built the same—do you know how insulation quality impacts performance and lifespan?

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 ...

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 ...
