First, set, rotor core troubleshooting, the rotor is stacked from each other insulated silicon steel is the magnetic circuit part of the motor. Set, the main reason for the rotor core failure are the following. ① bearing a long time, excessive wear and tear, resulting in stator and rotor phase friction, so that the core […]

Ten reasons for motor vibration 1. Rotor, coupler, coupling, transmission wheel (brake wheel) imbalance caused. 2. Iron core frame loose, diagonal keys, pin failure loose, loose rotor banding will result in some imbalance in rotation. 3. linkage part of the shaft misalignment, the center line does not coincide, centering is not correct. The main reason […]

An AB servomotor (MPL-B640F-MJ24AA) was disassembled to check brakes due to customer ignorance. The encoder attached to the rear of the motor was also removed (unmarked) and the encoder was sick. The SRM50-HFA0- K01. After loading the brake no problem, but speed problems. Servo drive error E18 OVER SPEED or E24 velocity error. Emergency zeroing […]

Inverter is a sophisticated electronic equipment, operating conditions have many restrictions, the use of the inverter there are many qualifications. The following summarizes the use of the inverter environment requirements: No corrosive gases, vapors, dust and oily dust, direct sunlight. No floating dust and metal particles place. Ambient humidity 20% ~ 90% RH. Vibration is […]

How to achieve precise servo control: 1) There is a problem of AC zero crossing, so the AC current can be controlled by a half cycle as a pulse. 2) AC motor, a magnetic pole, a phase problem, to the phase group as the unit commutation, phase control can be accurately achieved; 3) DC motor, […]

[Troubleshooting] A surface acoustic wave touch screen system, where the finger touches the screen of the display, cannot normally perform the corresponding operation. [Fault Analysis Processing] This phenomenon may be the sound wave Wei Lun touch screen in use for some time, the reflective stripe around the screen is covered with dust, use a dry […]
