As is well known, electric rotary stages rely on the rotation of motors for operation. A customer has reported that the motor of the precision electric rotary stage does not rotate and there is a buzzing sound after being powered on. What is the reason? Below, the manufacturer of PDV electric displacement stage will briefly answer this question.
1. Fault caus
① There is an open circuit in the rotor winding (one phase disconnection) or a loss of power in one phase of the power supply;
② The beginning and end of the winding lead are connected incorrectly or the winding is internally connected in reverse;
③ Loose power circuit contacts with high contact resistance;
④ The motor is overloaded or the rotor is stuck;
⑤ The power supply voltage is too low;
⑥ Small motors are assembled too tightly or the grease inside the bearings is too hard;
⑦ The bearing is stuck.
2. Troubleshooting of precision displacement platform
① Identify breakpoints and repair them;
② Check the polarity of the winding; Determine whether the end of the winding is correct;
③ Tighten the loose wiring screws, use a multimeter to determine if each connector is false, and repair it;
④ Reduce load or detect and eliminate mechanical faults,
⑤ Check if the specified surface connection method is mistakenly connected; Is the voltage drop too high due to the thin power wire.
