Nettet33. Motors may also be started by variable frequency as covered in the chapter on VFD's. Common insulation systems today are classes A, B, F and H having temperature limits of 90, 130, 155 and 180 °C respectively. Motor insulation life is generally considered to be halved for every 10° C rise up to these limits. NettetDetecting Insulation Failures with MCA. Winding Insulation. Motor Circuit Analysis (MCA™) injects low voltage AC & DC voltage to exercise the winding insulation system, while the motor is deenergized. When the insulation system begins to undergo chemical changes, it affects the capacitance (C), and inductance (L) of the coil system.
Nettet10. sep. 2013 · With Class F insulation, the maximum allowable temperature rise ranges from 105 to 115 C for the motor’s winding insulation, depending on how the motor is configured. For example, if the motor that was reported to be “running hot” has a 1.15 service factor, its maximum temperature rise would be 115 C plus the 40 C ambient.
