A VFD or Variable Frequency Drive is a kind of motor control device which helps in driving electric motor. It changes the voltage supplied and frequency of the electric motor to boost its performance. Finding the right VFD can be a difficult task because there are uncountable variables with every system and application. However, suggestions and helpful guidance from trusted Variable Frequency Drive dealers can ease away the purchase. VFD is also known AC drive, inverter or adaptable frequency drive.
Hertz is the unit of frequency, which is directly linked to the speed of the motor or its revolution per minute. To put it differently, the revolution per minute or RMP is directly proportional to the frequency. If a system does not need an electrical motor to work at full speed, the VFD acts as a device for ramping down the voltage and frequency as per the load requirement of the electric motor. When the system’s motor speed requisites changes, the variable frequency drive can easily turn down or turn up the speed accordingly.
Advantages of VFD
One of the most important advantages is the ability to bring down energy consumption which is linked to speed control. Sheaves, belts or gearboxes are used for speed reduction, but most of the time the motor’s speed is not controlled by these. However, a VFD can decrease the original motor speed, when the current go beyond rated amps. As a result, the usage of energy is also reduced, and thereby, saves you money.
Over a last couple of years, the demand for VFD used in induction motors is increasing. The reason behind the demand is for saving more energy and for automating the machines. In order to address to this demand, Bharat Bijlee Energy efficient IE2 motors have been introduced. These superior performance automation solutions are helping customers decrease life-cycle energy expenses for their motor-operated applications. These have user-friendly operations, compact design and easy installation features.
Variable Frequency Drive helps in speeding up the motor gradually, hence it also reduces motor malfunctioning and mechanical maintenance costs.
Increased efficiency of motors in hazardous area
Hazardous areas are the places where explosive warnings are given or special precautions are required for installation, construction or usage of equipment. Any residential, commercial or factory environment has its respective fire hazards. There are also chances of blaze breaking out and motors catching fire due to various reasons. Bharat Bijlee Flame Proof Motors are being used across all industries. As the quantity of explosion-resistant motors is growing, so has the usage of Variable Frequency Drive to control in changeable speed applications. In majority of instances, the VFD is installed outside the hazardous zone, because it functions better and can locate the variable speed of the motor.
For premium motor efficiency, Bharat Bijlee Energy Efficient IE3 Motors are used. These devices are also helping to lessen CO2 emission and its level every year. Also, a great way to reduce energy consumption or improve the efficiency of motors is by ensuring you don’t overrun or oversize when not needed.
