Generator should be long time need not,(1) cause before delivery contains the remanent magnetization in core,lose excitation coil can't afford to electric vehicle motor build its magnetic field,then a generator under normal,send electric motor cooling fanout electricity,this kind of phenomenon,new long-term unused units or more.(2) the deficiency of another,the magnetization electricity,numerous machine back Old trouble again,this kind of phenomenon cannot effect a radical cure thoroughly Emergency treatment: The former battery copper ring on the magnetization can be (but note polarity),the latter with the following methods 1) equipped with excitation button,click the field button, 2) no excitation button,using battery for its magnetization www.dongfeng- motor.com 3) often pick a light bulb in the load,overdrive for a few seconds,effective,do not prevent try.
