The output voltage

Of the output voltage is on-board host on-board power amplifier output audio signal voltage,usually under 10 v.On-board host in the car audio system similar to the original function of DVD home theater,but inside the car space is precious,so integration is very demanding.In order to satisfy ac induction motor the space requirements,many car the host with the function of the power amplifier,can be connected directly to the ac electric motor speaker.But a host of power amplifier sometimes can't satisfy people's needs,so a lot of host electricalmotor1.blogspot.com (but not all of the host) can connect independent power amplifier.Unlike home theater VCD,a prerequisite for the host output voltage is higher,so the different host to the requirement of diesel generators prices the power amplifier,when the choose and buy should pay attention to collocation.If you choose the car amplifiers,had better choose lead high output current host,currently in power output is preferred.

Three-phase no-load current of 2.5 0.75 KW motor,what reason be

Two 0.75 KW..Grade 4...380 v...The motor..No-load current is between 2.3 to 2.6...Work environment textile factory..'a lot...Rated current of the motor is only 2.2...Normal no-load current is around 1.6..Time machine completely under ac electric motor the condition of no load over current...Due to the current big.So high temperature sharply born..Will soon..Overheating damage..Do not say the reason...thank you Problem complement: I thank two answer first..Disease,and together,the two are not normal before..In a few years later.You'll find the bad one current is increased.[.Repair of the motor are friends.Eliminate offline ribbon..] ...Until now,with or without load..

Motor current wholesalemotor.blogspot.com is bigger...Last year when the motor current in 2.0 A..Now 2.4-2.5 A...Motor shaft sleeve inside and outside in good condition...Have not completed...Don't go...Only electricity pilot time to run the old hot..Often the temperature in the 60-80 degrees...Wiring is right...Are the normal installation... There is a reason,is you pick the wrong wiring.380 v y connection.You make into 380 v delta connection.So,motor heat quickly.This is one magnetic generator of them.In addition,the machine is idle for a long time,must have certain load.If it is in use for a period of time after the scenario (excluding intervention had gone wrong),should be the result of mechanical failure.1 bearing damage increase torque resistance.Run 2 bearing outer ring,which leads to the bearing wear gaps (cover),the rotor eccentricity running and friction with the stator (boring),increase the electric motor 12v 500w torque resistance.What type of your motor,then measure the core size,what are you friends with line,around a few laps? I help you check it.Is estimated to be between winding insulation damage,it is recommended that you access the winding.
