Siemens servo motor does not rotate

Siemens axis servo motor does not rotate (focusing on motor maintenance for ten years) process: Step 1: First, inquire about the fault phenomenon and on-site situation of the damaged electrical equipment from the user. Step 2: Analyze the causes of such faults based on the user's fault description. Step 3: Thoroughly clean the machine, identify damaged components, and analyze the feasibility of repair and restoration. Step 4: Based on the location of the damaged component, identify the cause of the damage to avoid similar malfunctions in the future. Step 5: Provide a detailed inspection report and repair quotation, and after Party A confirms the quotation, carry out the repair. Step 6: After repair, conduct a load test on the equipment, notify Party A of normal operation, and ship the goods upon payment. Siemens servo motor shaking and not rotating fault handling: 1 Electromagnetic reasons lead to vibration in the power supply: three-phase voltage imbalance and three-phase motor phase loss operation. In terms of stator: the stator core becomes elliptical, eccentric, and loose; The stator winding experiences wire breakage, ground breakdown, turn to turn short circuit, wiring errors, and unbalanced three-phase current in the stator. Rotor malfunction: The rotor iron core has become elliptical, eccentric, and loose. The rotor cage bar is welded to the end ring, the rotor cage bar is broken, the winding is incorrect, and the electric brush contact is poor. 2. The vibration of the motor is often caused by uneven air gap, resulting in unilateral electromagnetic tension, which in turn increases the air gap. This electromechanical mixing effect is manifested as motor vibration. The axial movement of the motor is caused by electromagnetic tension due to the gravity or installation level of the rotor itself, as well as the incorrect magnetic center, resulting in axial movement of the motor and increased vibration of the motor. In severe cases, shaft wear can occur, causing the temperature of the bearing to rise rapidly. >>The gears and couplings connected to the motor are faulty. This type of malfunction is mainly manifested as poor gear meshing, severe tooth wear, poor wheel lubrication, skewed or misaligned couplings, incorrect tooth profile and pitch, excessive clearance or severe wear of gear couplings, all of which can cause certain vibrations. The solutions are: 1. The encoder in the servo controller, 4. If the encoder or encoder cable is damaged, replace it. 5. If the encoder interface of the servo controller is damaged or has poor contact, repair it.

Currently, our company only undertakes the maintenance of Siemens industrial control equipment, because... The sentence is:, Trusting Siemens bed axis servo motor does not rotate (focusing on motor maintenance for ten years), which is commonly used in servo motor applications. However, after a certain period of operation, various faults will occur in servo motors. If we can timely determine the cause of the fault and do some simple troubleshooting, it will be helpful in preventing the fault from expanding. In our work, we have summarized some fault causes and troubleshooting for servo motor users' reference: 1. After power on, the motor cannot rotate, but there is no abnormal noise, odor or smoke. 1. Reason for malfunction: (1) The power supply is not connected (at least two phases are not connected); (2) The fuse is blown (at least two phases are blown); (3) The overcurrent relay is set too small; (4) Control equipment wiring error. 2. Fault handling (1) Check whether there are breakpoints at the power circuit switch, fuse, and junction box, and repair them; (2) Check the fuse model, cause of melting, and replace the fuse with a new one; 1. In order not to damage the electromagnetic separator of the main drive DC motor brake, it is necessary to consistently clean the yoke, armature, friction disc and other components of the DC motor brake separator, and make their speed adjustable. Due to the absence of oil stains and poor suction of electrical components, the temperature rises and the insulation of the collecting coil of the brake electromagnetic separator is prematurely damaged, causing damage. Attention and protection should be taken. Regularly use a brush dipped in gasoline to clean oil stains and other impurities, remove paper wool, dust and other impurities from all electrical components in the DC motor electrical cabinet, in order to facilitate heat dissipation, ventilation and separation of the collector, loss, and red color. UCE extends the service life of electrical components. 2. The speed of the speed regulating DC motor gradually decreases after acceleration, causing it to stop. Observe the changes in the pointer of the ammeter inside the electrical cabinet of the speed regulating DC motor. When the speed of the DC motor is low, it is due to the main DC motor. The task current is small and there will be no gas. It is hoped that the speed will gradually decrease and stop. When the speed of the speed regulating DC motor increases and the power load is high, electrical component failures will occur. 3. In order to flexibly adjust the slip electric balance, the armature and magnetic pole rotor of the main driving DC motor are equipped with counterweight devices. At this time, it is necessary to stop the vehicle for repair, restore the dynamic balance of the armature and magnetic pole rotor, reset the original balance position, and fix it properly to achieve balance. Ensure the main drive DC motor operates normally. 4. The abnormal slip of the DC motor in the main drive will cause vibration during operation, resulting in bearings. In this case, the damaged bearings must be replaced and lubricating grease must be added. Under normal circumstances, all parts of the local mechanism should be cleaned and lubricated to ensure its normal operation. The main drive is a DC motor. 5. The periodic decrease in host speed is mainly caused by mechanical local faults
