Regardless of the method used to detect winding temperature, the total, or hot spot, temperature is the real limit; and the lower it is, the better. Don’t let excessive heat kill your motors before their time.
This manual covers horizontal and vertical squirrel-cage induction motors in the 300 to 5,000 horsepower range, low- and medium-voltage. Most of the principles covered apply to other sizes as well. This manual focuses primarily on IEC motors and standards.
This presentation addresses the topic of a various temperature sensing devices including RTDs, thermostats, thermocouples and thermistors. The advantages of each and the proper application will be covered.
Thermistors, derived from the term thermally sensitive resistors, are a very accurate and cost effective method for measuring temperature. Thermistors are usually two-terminal semiconductor devices made from semi-conductor materials that have an electrical resistance that varies non-linearly with temperature. Some materials provide better stability while others have higher resistance ranges and are fabricated into smaller thermistors. Each specificthermistor has its own unique resistance versus temperature characteristic.
This presentation provides an overview of ambient, winding temperature rise, and winding temperature, and addresses detectors for measuring winding temperature, namely thermostats, resistance temperature detectors (RTDs), thermocouples and thermistors.
Often during the rebuild and overhaul of a piece of electrical apparatus, we are faced with the challenge to identify the type of temperature detection devices that need to be replaced. The identification process should start at the beginning of the rebuild when the apparatus starts its way through the service center. Most major manufacturers identify the temperature detection device on a connection plate in the motor terminal box and many have a connection diagram indicating the type of device used. You can also refer to the manufacturer's catalog where they identify the type of temperature detector that has been used. Needless to say, it is usually too late to start identifying the temperature sensor after the winding is reclaimed and the device is now dust. Because that does happen, let's look at the styles and types of winding temperature detectors. Types of temperature detectors discussed include: Resistance Temperature Detectors (RTDs) Thermocouples Thermistors Thermostats
When we mention temperature detectors for motors we usually think of winding temperature detectors. However, temperature detectors can also be used to monitor bearings and airflow. In this article we will describe the more common types of temperature detectors and how they can be applied to windings, bearings and to check ventilation (airflow).
This 40-page booklet provides great advice for obtaining the longest, most efficient and cost-effective operation from general and definite purpose electric motors.
