Motor winding heating
Nettet25. jul. 2024 · Discussion Starter · #1 · Jul 20, 2024. After 34 years of doing industrial work I am beginning to work on synchronous motors. The motors that I work on are 40's vintage 2400 volt . To heat the motors in the off cycle they have a low voltage high current transformer that feeds a bridge rectifier that feeds DC to the stator winding of the motor. NettetA little known aspect of preheating is that it relieves the mechanical stress cracks, termed “crazing,” on the magnet wire insulation coating that occur during coil winding and insertion. Epoxy B-stage materials can be set by preheating, provided the preheating time and temperature meet the epoxy’s curing requirements.

Nettet10. sep. 2013 · If the ambient temperature is 35 C (95 F), the winding total temperature would be: 65 + 35 = 100 C. If motor is so constructed that its surface is about 20 C cooler than the winding, the surface temperature would be: 100 – 20 = 80 C (176 F)—i.e., much too hot to touch safely! Remember that this is a conservative design, so the surface ... Nettetmedium and high voltage induction motor protection RTD are commonly used. A virtual model has been represented to simulate the temperature sensor thermal time constant under different thermal conductivity and thickness of winding magnet wire insulation. Key words: induction motor, protection, temperature sensor, thermal time constant, heating.
