One of the problems associated with microwave oven transformers is that, due to core saturation, they take very high magnetising currents and get hot even at low loads. Although the transformer is probably good for 50A with a little air over the secondary winding, I've limited this design to 25A due to the semiconductors available. / Base parts for Maytag UMC5200BAS - AppliancePartsPros. For use with the following LG Electronics models: LRM1260SW, LRM1250B, LRM1250W01, MS1245QR. A microwave oven transformer (MOT) is not (despite the name) an ordinary transformer, it is a specifically designed non-ideal transformer. Microwave Oven Electrical Circuit Requirements. Introduction In this article I am going to present my struggling about rewinding a microwave oven transformer (MOT) in order to make a low voltage (20-30V) but high current (15-30A) transformer. Microwave ovens contain a very powerful high voltage transformer (MOT = microwave oven transformer), see photo.

A given transformer is most likely to saturate when its primary is run overvoltage and there is NO LOAD current drawn from the secondary. this is nice one. It’s possible to download the document as PDF or print. Unlike the classic microwave oven transformers (where one side of the winding is grounded), this means that the secondary must be well insulated from ground on both sides. One of the problems associated with microwave oven transformers is that, due to core saturation, they take very high magnetising currents and get hot even at low loads. The load was a bit more problematic. 6 # 5304461114 Thermal Cut-Out, oven, 170 C 7 5304464198 Lamp, oven light 8 # 5304463785 Lampholder, socket 9 # 5304461119 Motor, fan 10 # 5304470538 Transformer, power 11 # 5304470539 Capacitor, high voltage 12 # 5304480635 Rectifier Assembly, high voltage 13 # 5304501808 Magnetron 14 # 5304498736 Motor, turntable.
