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 ...

Stepper motors contain coil windings that require resistance measurements. Measuring resistance in a production environment often requires some special circuits that minimize errors. Resistance is ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...
