How to service brushless motor everyone know how to repair a brushless motor, if you also have doubts on this question, and see it together. About this problem, we want to know, brushless motor winding is not easy bad, mostly hall element is damaged, then there is damage to motor bearing short of oil. And if it is a hall element damage wouldn't have changed, in brushless controller can be directly, if is the rear wheel bearing problems will have to put the motor the pick, open the cover easily. About how to repair the knowledge of the brushless motor, small make up it said so much, if you have questions, welcome to inquire. Is a way of excitation brushless dc gear motor, brushless dc gear motor in operation is has a certain field, it is divided into the mode of excitation, to specific as follows. , separately excited dc motor excitation winding and armature winding coupling relationship, while the other dc power supply for power supply of dc motor excitation winding called separately excited dc motor, permanent magnet dc motor can also be used as a separately excited or self excited dc motor, generally called for the permanent magnet excitation type directly. Dc motor, shunt shunt excitation winding dc motor in parallel with the armature winding, a shunt generator, is made by the machine itself for exciting winding terminal voltage power supply; As a shunt motor, the field winding and armature sharing the same power, tell from the performance of the same as the separately excited dc motor. Series dc motor, series dc motor excitation winding and armature winding in series, and dc power supply. The excitation current of dc motor's armature current. Compound, the compound dc motor dc motor has two exciting winding shunt and series. If the series and the magnetomotive force produced by winding magnetomotive force produced by the shunt winding in the same direction is called cumulative compound. If two magnetomotive force in the opposite direction, it is called a differential compound. Knowledge about brushless dc gear motor was first introduced to here, still have more knowledge about the product, welcome you to continue browsing, and at the same time, thank you very much for reading. Teach you how to maintain the brushless dc motor when they purchase of brushless dc motor, thought of how to maintain? Small make up to introduce the maintenance method of this motor for you, hope can help for you! 。 Familiar with the structure characteristics of the brushless dc motor and maintenance technical requirements; 。 Detailed check each part of the motor temperature, noise, vibration, etc. , and test the voltage, current, speed, etc. , a record; 。 With compressed air blowing off the dust on the surface of the motor, and the dirt on the surface of the motor to wipe clean; 。 Cut off the power supply, and the dismantling of electrical wiring, choose suitable insulation resistance by megger test motor, and make records. Brushless dc motor has good stability, strong adaptability, repair and maintenance is simple, you have mastered the maintenance methods of the motor, can more skilled use of the motor, prolong the service life of the machine. Brushless motor brushless self-control type inverter motor is adopted in the control type inverter, it is different from general inverter. Adjust its output frequency is not independent, but by installed on the shaft of the synchronous motor rotor position detector control. Whenever the rotor turns must I position (E. g. ° or ° Angle), the position detector to produce the corresponding signal, applied to the corresponding semiconductor components, make the corresponding phase winding electricity, torque is produced. Motor rotor in each turn a pair of poles, semiconductor devices in turn conduction week, inverter output ac change accordingly a cycle. So self-control type inverter output frequency and the rotational speed of the motor is always in sync, there will not be out of step. In the brushless motor, inverter consists of a transistor. Because the transistor has the ability to turn off, as long as its base on the control signal disappears, the transistor will shut off by itself, so it is easier to control. In the brushless dc motor of large capacity, the inverter is composed of thyristor. Thyristor is not the ability to turn off, can't remove the trigger signal so that it is shut off. So when the brushless motor current need to globe, let another common electricity, how to shut off the original forerunner of thyristor, the electric current is transferred to a new phase of thyristor, thyristor converter problem between is the key technology of thyristor motor.
