The Hot Issue of Motor Temperature Ratings | EC&M

In a T frame motor with Class B insulation, the extra 25°C of thermal capacity (Class B compared to Class A) accommodates the higher temperature rise associated with the smaller T frame motors. For example: A standard T frame motor might have a rating of 40°C ambient, 80°C temperature rise, and a 10°C hot spot allowance.

Measuring Vibration with Accelerometers

Measuring Vibration with Accelerometers

2020-7-15 · Vibration is most commonly measured using a ceramic piezoelectric sensor or accelerometer. An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. Accelerometers are full-contact transducers typically mounted directly on high-frequency elements, such as rolling-element bearings, gearboxes, or spinning blades.
