Motor small household electrical appliances in the blocking is how a way to protect the protection of the law? This is also a practical problem for some electrical engineers. Then today, from the electronic technology small for everyone to bring a description of the over-current protection strategy of self blocking scheme in motor recovery fuse in small household appliances.
Soybean Milk machine, mixer, everyone is familiar with, contact a lot, to avoid importing things too much, rotating wheel stuck, causing motor stalling and burning motor, the design engineer will usually design temperature or over-current protection measures, now more mature application program is used to do the self recovery fuse protection is the most simple and effective way. Depending on the motor operating current and stuck at the time of the current up to a value to choose the relevant models, you can solve the problem of motor blocked. When the motor blockage, the motor current will be motor working current several times, usually can reach at least 4 times to 5 times or more, so the current flowing through the motor armature, will cause the motor temperature rise sharply, resulting in electric insulation performance decreased significantly, most caused by rotor or stator winding paint the envelope insulation melting caused by short-circuit burning dangerous phenomenon.
Using the self recovery fuse as blocking protection of the motor, when the self recovery fuse current reaches a certain value, self recovery fuse fever to the Curie temperature, we can immediately to the motor protection, there is no current through the fuse and the other is a one-time insurance can not be compared, tage is TG card electronic series resettable fuse, as long as the current work, when the current block, considering the action time of protection, select the appropriate model, is connected in series with the motor, you can.
For more information about the story, the friends of a clear self recovery fuse in the motor small appliances in the blocking of the flow protection program! If you want to select more clearly self recovery problems related to fuse models, can directly contact the Sales Department Manager Zhang tage electronic website in electronic dance.
