Abstract: the stepper motor can be divided into stepper generator and stepper motor, the stepper generator and its widely used in large power plant, the optimized application needs for its correct use, otherwise it's easy to fail, and is one of the generator overheating. This paper is to introduce the stepper motor step generator will of overheating and solution. A, not according to technical condition of the stepper motor running step generator required if there is no provision in the practical application of technical conditions of operation, for example: the load current is too large, low frequency, the stator voltage is too high, the low power factor, etc. , this is you need inspection on monitoring instrument, check whether the normal, if not normal you need to carry on the corresponding adjustment. Second, the three-phase unbalanced load currents if unbalanced three-phase load current of generator can also cause of the stepper motor step generator overheating phenomenon, and once this imbalance reached when the situation is serious imbalance, creates negative sequence magnetic field, this will cause the increase of the loss, leading to the ferrule and pole winding parts fever phenomenon. Solution is: adjust the three-phase load, ensure each phase current balance. Three, and blockage of the air duct if stepper generator of stepper motor overheating phenomenon, also may be because of air duct was caused by the dust jam, because blockage can lead to poor ventilation, and will affect the heat dissipation of the generator. The solution: removal of dust, keep the wind clear. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
