discount Synchronous Motor professional motor manufacturers, to provide you with an overview of motor knowledge:
Many people do not know how to judge the performance of servo motors and how to choose servo motors, micro-motors, I will tell you how to judge the performance and selection of servo motors.
Servo motors are divided into stepper motors, DC brushless servo motors, DC brushless servo motors, and AC servo motors according to the usual distinction. With the increasing progress of science and technology, many special servo motors have emerged, such as piezoelectric ceramic Motors, linear Motors, and sound loops. Motor, Here we mainly talk about the selection of servo motors in the usual sense.
We all know that because the electrical current is too large, the voltage of the power supply is too large, the single phase operation, the mechanical injury, the poor manufacturing, etc. caused by the insulation damage, the three-phase motor winding group short-circuit between turns, short-circuit between windings, short-circuit between windings and short circuit between windings. For this phenomenon, we must carry out several inspection methods:(1) External observation method. Observe whether the junction boxes and winding ends are charred, and if the winding is overheated, it leaves dark brown and has a bad smell. (2) Method of temperature examination. The empty load runs for 20 minutes(stop immediately if an anomaly is found), and touch each part of the winding group with the back of the hand if it exceeds the normal temperature. (3) Electricity test method. Measuring with an ammeter, if a phase current is too large, it indicates that the phase has a short circuit.
