Tongmao linear motor to teach you the test method, the linear motor is damaged? How to distinguish it? How to test it out? Are you bothering with this problem too? Do not be afraid, Tongmao linear motor to help you teach you how to tell the linear motor is damaged small way.
To distinguish whether to check the linear motor is damaged, then we need to use a tool, its name is multimeter. Multimeter is the basic tool to measure the quality of linear motor. A multimeter to determine the single-phase or three-phase motor is not burned The method is only applicable to the coil winding DC resistance of more than 1 Euro small motor.
1. Three-phase motor is burned out of the judgment is relatively simple, with a multimeter to test the three-phase winding DC resistance is balanced, if the imbalance can determine the three-phase motor is burned.
2. The single-phase motor start winding DC resistance is greater than the operating winding, the easiest way to determine is;
⑴ first with a multimeter were measured public terminal to run the winding end and the start winding end of the DC resistance
⑵ Then use a multimeter to measure the end of the winding to run the winding DC resistance.
⑶ If the two measurements in ⑴ and ⑵ and the measured value is not equal, then the linear motor must be burned. If the same, it is best to compare with the same type of linear motor, or find the linear motor factory parameters for comparison. To determine the quality of linear motor, add that the amount of single-phase motor should disconnect the capacitor. Single-phase motor is a short circuit you have a normal case of resistance as a reference. Simply use the smell and look at the two methods is good.
