Winding temperature is often not measured directly due to the challenges associated with placing sensors within the winding itself, which can be intrusive and affect performance. Instead, indirect methods, such as measuring the temperature of the housing or using thermal models, are employed to estimate winding temperature. This approach minimizes disruption and allows for easier monitoring while still providing accurate temperature assessments. Additionally, indirect measurements can help in assessing temperature changes over time without interrupting the operation of the equipment.
The commonly used sensor for measuring motor winding temperature is the thermocouple, specifically type K or J thermocouples. Additionally, resistance temperature detectors (RTDs) and thermistors can also be employed for this purpose due to their accuracy and stability. These sensors provide reliable temperature readings, which are crucial for preventing overheating and ensuring the safe operation of electric motors.
If the series field winding of a motor is connected directly across a 120 V DC supply, the current that flows through the winding would depend on the resistance of the winding itself, as per Ohm's Law (I = V/R). If the resistance of the winding is known, you can calculate the current by dividing the voltage (120 V) by the resistance (R). Without knowing the specific resistance value, the exact current cannot be determined.
An 'armature winding' is the rotor winding, and the 'field winding' is the stator winding.
Winding: To wind the coils into the slots on the stator or rotor and connecting them up to form a winding. Re-winding. Is to remove the old winding and doing what I explained above.
In the case of a capacitor-start/run single-phase induction motor, the main field is provided by the main (running) winding, and the capacitive branch is the auxiliary winding. In the case of a capacitor-start motor, the main winding is the running winding and the auxiliary winding is the starting winding.
A thermometer is a devise for measuring temperature
what are the different skills in measuring temperature
The SI unit for measuring temperature is Kelvinkelvin kelvin
There are no units for measuring the use of temperature.
It depends on the load
Thermal energy in physics can be found by measuring the temperature of an object or substance. This can be done using a thermometer or other temperature measuring devices. The amount of thermal energy present is directly related to the temperature of the object, with higher temperatures indicating higher thermal energy.

measuring temperature the metric system of °C is used.
FALSE. Measuring the ambient temperature of the frozen food compartment does not accurately reflect the temperature of the frozen food products themselves, as the air temperature can differ from the temperature of the food items. It is best to use a thermometer to measure the temperature of the food directly for a more accurate assessment of its safety and quality.
There are three primary systems for measuring temperature: Fahrenheit, Celsius, and Kelvin.
Celsius, Fahrenheit, and Kelvin are three common units for measuring temperature. Each unit has a different scale for measuring temperature.
