To prevent a motor from burning up, you must provide a means of protecting it from overcurrent (overload, short circuit, or ground fault). If you can remember not to confuse motor protection with ...
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 ...
Megohmmeters (meggers) are electrical meters used to check the resistance and condition of the motor windings and the condition of the refrigeration and oil environment around the motor windings. A ...
AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed without complex ...
Medium-voltage motors are critical to a facility’s power system. Not only are they expensive, but their failure can have crippling, long-lasting impacts on a plant’s operation. As such, properly ...
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, ...
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 ...
