How to Repair Your Servo Motor

Figure 1: The servo motor is used in the industry.

First, you need to do the following things before starting the servo motor. Measure the insulation resistance (for low voltage motor it should not be less than 0.5m). Measure the power supply voltage, check the motor connection, as well as the power supply voltage. Examine whether the starting equipment is in good condition. Check if the fuse is suitable. Inspect whether the motor is grounded and zeroed. Check if the transmission device is defective. Examine the motor environment, and remove inflammable goods and other sundries.

Causes of Overheating of Servo Motor Bearings

The inner and outer ring of the bearing is too tight. The fault of the shape and position tolerance of parts, in which the coaxiality of the frame, end cover, shaft and other parts is not good. Improper selection of bearings. Bearing lubrication is poor or bearing is not clean, and there are sundries in the grease. Axial current. Improper installation of the unit. For instance, the shaft of the motor and the dragging device meets the coaxial requirements. The pulley is pulled too tight. Bearing maintenance is not good, grease is insufficient or over the service life, dry and deteriorated.

Cause of the Three-Phase Current Imbalance

The imbalance of the three-phase voltage. Bad welding or bad contact of a phase branch inside the motor.

HZ-3521A three-phase watt-hour meter field calibrator is specially designed for on-site inspection of high-voltage power grid metering devices and fault detection. The instrument USES high-precision internal transformer and clamp type transformer for sampling, so that operators can quickly, safely and reliably measure meter recording errors and wiring errors. It provides an effective basis for electric power system inspectors to check electric theft and leakage, find out the failure of metering device, measure correctly and recover electric quantity.

Ülkelerin üç fazlı elektrik güçleri

Ülkelerin üç fazlı elektrik güçleri

Tek fazlı güç bugün daha yaygın olmasına rağmen, üç faz hala birçok farklı uygulama tipi için tercih edilen güç olarak seçilmiştir. Elektrik santrallerindeki jeneratörler üç fazlı elektrik sağlıyorlar. Bu, tellerin kalınlığını arttırmak zorunda kalmadan, ikiden sağlanabilecek üç tel boyunca üç kat elektrik tedarik etmenin bir yoludur. Endüstride motorları ve diğer cihazları sürmek için kullanılır.
