Stepper motor is in use process sometimes encounter unforeseen failure, these faults have a plenty of because of improper use, and more because there is no detailed understanding before using related condition attributes and the matters needing attention. In view of the step progress motor common fault, blog electronics (shenzhen) co. , LTD. Experts to answer one by one to you: 1, why can't a general motors used in plateau area? Elevation of motor temperature rise, the motor capacity (High voltage motor)Have an adverse effect and dc motor of the reversing should pay attention to the following three aspects: a. High altitude, the motor temperature rise, the greater the power output is smaller, but when the temperature decreases with the rise of altitude compensating and the elevation of temperature, the influence of the rated power output of the machine is the same b. When used in the plateau of the high pressure motor to adopt measures to prevent corona c. Altitude against dc motor commutator, pay attention to the material selection of carbon brush 2, why not light load motor operation are caused when the motor light load running: 1)Low motor power factor 2)Motor efficiency is low, will cause the waste of equipment, running economy 3, not the cause of the motor overheating have? 1)Heavy load 2)Lack of item 3)Air duct obstruction (4)Low speed running time is too long. 5)Too much power is glad to wave 4, for a long time without the motor input before what need to do? 1), measurement of the stator winding and the winding insulation resistance to earth insulation electrical Yin R shall meet the type: R> UN/(1000 + P / 1000)(MΩ)/ / * UN: motor winding rated voltage (V)P: motor power (千瓦)Under the UN = 380 v motor R> 0. 38 MΩSuch as the low insulation resistance, can be: a. Motor no-load running 2 & ndash; 3 h drying b. With 30% rated voltage of the low voltage ac electric flux into the winding or the three-phase winding in series with direct current (dc) after baking, keep c in 50% of the rated current. With fan into the hot air or heating element (2)Clean the fan (3)Replace the bearing grease 5, why does not start any motor in cold environment? Motor in the low temperature environment is too long will: 1)Motor insulation cracking 2)Bearing grease is frozen 3)Lead solder powder generation red joint motor should be kept heating in cold environment, therefore, in dealing with the winding and bearings operation ticket 6, what are the cause of the unbalanced three-phase current motor 1)Three-phase voltage imbalance 2)Motor phase within a certain branch welding is bad or contact 3)Motor winding interturn short circuit or to ground and short circuit (4)Connection error for more details please visit: WWW. bohongmotor。 Com 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.
