Linear guide rail sliding table module factory _ manipulator module _ cross linear module price quotation
motor familiar friends should know that motor generally fall into two categories, one is the servo motor, a stepper planetary gear motor. Servo planetary gear motor is superior to the stepper motor is very much, but because of the price of better than it USES is relative. If it is not too high requirements of precision mechanical products, the general selection step electric opportunity more affordable. As important as the motor and linear module, below small make up, and everyone talk about the cause of the linear module, stepper motor burn out!
1. Linear module, stepper motor for bearing damage, caused by end cover wear, spindle wear, sweep the rotor chamber, line package damage burn is a main reason;
2. Linear module out of step motor load, motor drag equipment abnormal vibration, abnormal external intervention. And artificial increase power can cause motor output is too large, such as current exceed the rating, the winding fever ranks, a little bit longer time can cause enameled wire insulation damage;
3. Linear module, stepper motor be affected with damp be affected with damp, because the insulation of the water or be affected with damp be affected with damp is reduced, is also a common cause of damage to do daily protection. Pay attention to and insulation test on a regular basis. Especially with frequency converter drive motor, more need to be careful this, otherwise can even inverter a damage;
4. Linear module of phase operation: if the stepper motor's noise is very big, and severe fever, this also is the deadly killer of three-phase asynchronous motor, the general running more than ten minutes is burnt out. If the power supply system lack of phase, is likely to cause more damage of electric motor.
5. Other reasons, such as voltage too low or too high, the vibration caused by loose terminal phase fault, pest damage, motor rated voltage and the actual voltage not cooperate; All sorts of decompression starter circuit fault transformation is caused, step electric pilot work time low pressure and so on.
