Motor thermal withstand curve
Nettetcurves for a 7000-hp, 900-rpm motor are shown in Fig. 1. The curves represent two initial conditions: the machine ini-tially at ambient temperature and the machine initially at oper-ating temperature. Fig. 1 7000-hp, 900-rpm Motor Thermal Limit Curves The thermal limit curves show only two of the possible condi-tions of a first-order thermal ... NettetThese formulas, known as i2t methods, measure RMS current as it moves through motor windings. i2t is an expression of thermal energy that results from current flow. In fuses, this expression happens in: Melting i2t – The current required to melt a circuit; Arcing i2t – Thermal energy passed by a fuse during arcing.

Nettet1. feb. 2011 · Re: Motor Thermal Curve. 01/31/2011 10:57 AM. There probably is a method to do this but you must consider the legal problem first. The motor manufacturer has probably provided two temperature windows for this motor. One temperature range for the powered operations and one for the unpowered storage. Nettet2 timer siden · That thermal energy increases the temperature of the cell, the increased temperature drives faster kinetics, and more heat is released, further driving up the temperature. Eventually, you can get to a tipping point and, essentially, the cell catches on fire. Thermal propagation occurs when that first cell in thermal runaway causes its …
