Construction of 400V AC Motor
The construction of a 400V AC motor includes several components. The rated efficiency of the 400V AC motor is significantly lowered by affecting its members. Some of these items are enlisted here briefly.
The Bearing System
All the IEC low voltage motors of Longbank belong to several series having different models. These series are IE2, IVFE2, YBX3, IE3, IE4, etc. All these motors have bearing systems that can be permanently or temporarily (greasing is done in intervals).
These bearings can be free to move, or they can be joined together. In contrast, the floating bearings belong to motors having a frame size of 80-160. The central role of these bearings is to keep a specific distance between stator and armature while providing support to the moving items.
Grease Life and Re-Greasing Interval
Grease life is nothing but a bearing’s lifetime. Both these run side by side. Any variation in the grease composition will drastically affect the bearing’s lifetime. Longbank’s team is highly expert in manufacturing the 400V AC motor by following all the motor specifications. For greasing, different kinds of oils are used.
The lifetime of some motors can be enhanced significantly for re-greaseable motors by oiling them frequently. It shows that the lifetime of the bearing can be controlled. Several factors affect the motor’s uniform functioning, which can drastically change the motor’s efficiency. Herein we have described some of these factors:
- External temperature
- Mounting operations
- Speed f motor
- Bearing size
- Load Size and weight
If the 400V AC motor’s vibration is controlled, you can adjust the rated speed of the motor accordingly. Otherwise, it will exert more radial and axial pressure on the bearing, lowering its lifetime. A hot and cold environment can also affect the maintenance and re-greasing intervals of the 400V AC motor.
Vibration
The motion of the rotor generates the vibration. The rotor can be termed an armature with metals in its structure for generating north and south poles. When an alternating current passes through these metals, magnetism is generated. These rotors are dynamically stabilized using a half key.
Anti-Condensation Heater
In the case of hot summer weather, the temperature can cause the condensation of the windings around the stator. This problem can be resolved by using anti-condensation heaters in the 400V AC motor. The motor and these anti-condensation heaters work alternately.
Rated Output
If you want to achieve the rated output of the 400V AC Motor, then you must keep all the standard operating conditions in mind. These common conditions are temperature and altitude. The temperature should be between -15oC to 40oC, and its height above sea level is 1000m.
Voltage and Frequency
The 400V AC Motors of categories A and B are IEC60034-1 verified. Category A’s voltage and frequency fluctuations are ±5 % and ±2%, respectively. Similarly, the variation in voltage and frequency f of category B are ±10% and +3% / -5%. The temperature of category A motors is 10K higher than category B.
Features of 400V AC Motor
Each motor is constructed according to its structural features, which vary according to the series type. Each series offer various kinds of models of the 400V AC Motor. Some of the features of their quantitative as well as qualitative analysis have been mentioned over here:
- The lifetime for permanent lubrication is higher than 20,000 hours.
- While the lifetime for re-greaseable bearings is more elevated than 40,000 hours.
- If the coolant temperature (CT) is enhanced by 10K, the lifetime of bearings’ grease decreases by one-half.
- The power of the anti-condensation heater of FS80 to FS355 ranges from 0.75kW-2500kW depending upon the type of series and its category.
- The potential difference between FS80 to FS355 is 400V.
- The frame of the motor is sturdy due to cast iron.
- It has a vertical-horizontal radiator structure.
- The 400V AC motor has a beautiful outlook with good mechanical strength.
- Energy losses are maintained by installing various types of laminations.
- The stator and rotor contain an iron core that acts as a magnet.
- The electromagnetic wire is highly insulated to reduce the damage to other components.
- The electrical properties of the stator’s windings are improved by VPI coating.
- For ventilation, the structure of the motor is divided into internal and external air paths.
- Internal heat is forwarded towards the inner warmth, removing a path through the internal fan and rotor air blade.
- When the external heat remover dissipates the heat on the base shell, the internal temperature is controlled.
- The rotor contains aluminum or copper for generating north and south poles.
- The G1.0 level calculates the air gap between the stator and the rotor.
- The axial motion of the fan in the external fan is maintained to dissipate the heat effectively.
- At different frequencies, its rpm is 1800, depending on the model type.
- The external fan can also minimize the ventilation noise.
