Dc motor can run in a state of long-term, stable weak magnetic
the first: dc motor in a weak magnetic environment that can be, and weak magnetic is to increase the speed of the motor
2: weak magnetic motor speed has increased, the dongguan yuntai motor, but reduces the torque, that is to say, when not given weak motor can drive the 5 tons load to reach the rated current of the motor, when the weak magnetic torque of the motor will decrease, there would be no also can drive 5 tons load, perhaps only to reach the rated current of the motor, drive 4 tons you excitation voltage is lower, the faster the speed of the motor, so the load that can be carried on the lighter.
the third: the excitation voltage weak magnetic voltage of fifty percent of its rated as the best, such as the excitation voltage is 180 v then you will be weak magnetic excitation voltage to 80 -90 v this position is weak magnetic point for the best. Inductive brushless motor excitation voltage is too low, easy to cause the stop don't stop immediately, instead will glide for a period of time to stop, we call this the 'speed', just don't know how do you address the situation.
4: for weak magnetic dc motor, and in what situations suitable for weak magnetic let me explain. If your motor his heavy load, and to the requirement of speed is not so high, so suggest you don't weak magnetic, because I have said, in front of the weak magnetic voltage is too low, but easy to cause the motor does not load. For material is lighter, faster, you can use to further improve weak magnetic motor speed increase in production. The situation of the weak magnetic mainly depending on the actual situation to decide.
the fifth: the current domestic best inner rotor brushless motor is the rc, its quality is very good also, torque is big.
