A Guide about Variable Frequency Drives

Variable Frequency Drives(VFDs) are the drives used basically in electrical, mechanical and electronics industry. These drives are reckoned among the revolutionary inventions of the electronics industry to serve many applications. These drives are in use from many decades. The main aim of VFD drive is to save the electrical energy of the mechanical devices. It means it is mostly attached with small and large machinery where there is a requirement of variable frequency.

There are a lot of manufacturers of the AC drive, DC drives, VFD and VVFD drives but Mifa Group is a renowned and most trusted manufacturer of VFD drive. These drives manufactured by this company are highly in demand of commercial and industrial lifts. These drives are very compact and incurred easy installation mounts. Due to the cost effectives, these drives are perfect for those having budget as a prime concern. In these cases, the control panel uses micro controllers which act as the processing units.

Two proximity sensors control the travel of the lift between the start and stop points in the vicinity of the halts in this travel. These sensors including the VFD drive are installed near to the doors of the lift. The interfacing of the drive near to the control panel is very easy. It includes three connections for slow speed, and fast speed. The drive is also gives a flexible interface to a number of programmable logic controllers in the market. You just need to have a PLC and the communication cable to connect the electric device. The main advantageous part of this drive is that it reduces the mechanical jerks which feel due to acceleration at the start and stop of the lift.

The drive acts as a n electric switch to control the power supply to distribute it at different frequency to the machines requiring different frequency. The rapid development of mechanized production, so we have high mechanical requirements are also increasing. Our company offers a wide range of variable frequency drives,welcome to cooperate with us!

Saving Energy with Variable Speed Drives

Bigger commercial businesses are always looking for ways to improve their productivity, services, and even client or customer outreach. First of all, saving energy is every business should consider. Variable Frequency Drives are durable enough to be used in both commercial and industrial applications. It is designed with the Lapp Surge Guard insulation system which includes a semi conductive layer made to withstand nonlinear power distortions. The VFD also disperses increases in voltage caused by wave reflection, spikes, in-rush current, and harmonics. The specific material used in the surge guard helps to prevent both conductor and cable failure which helps to cut out downtime.

Choosing to use a variable frequency drive from our company also comes with a myriad of benefits. Firstly, we will provide customers and potential customers with energy cost comparisons, so their customers know exactly what to expect. We advertise the return on investment for those who use a variable frequency drive range from six months to two years. Users of our products and services can also expect less wear and tear on their current equipment, which means additional money saved, and using variable frequency drives or variable speed drives is a fantastic option to consider for those who want an option that is more environmentally friendly.

VFDs also have some other uses. VFD cords are intended to be used in drive and motor applications, web presses, HVAC, conveyors, and in any on/off, slow down/speed up applications. These VFD cords have been proven over the years to take care of any motor-to-drive connection issues, plus they can help to save energy. VFD cables can be used both in the industrial environment as well as the commercial environment. We can offer you the best variable frequency drives. Make sure that as a consumer you trust the retailer or that you are going through a manufacturer approved retailer. Welcome to cooperate with us.

What Are Variable Frequency Drives?

Energy plays a very important role in industry , Industries could be classified into heavy energy consumer , medium energy consumer and low energy consumer . Organization have started doing energy audits in their plants , offices etc .Such studies has highlighted waste of energy and requirement of energy efficient technology. Variable Frequency Drives(VFD’s) are electronic motor drives that allow the user to control the rotational speed of alternating current electric motors. VFD’s control the motor by varying the frequency of the electrical power supplied to the motor. And a Variable Frequency Drive can save much energy.

VFD’s actually have many different names. They are known as variable frequency drives, adjustable frequency drive, variable speed drive, adjustable speed drive, frequency drive, A C drive, microdrive or inverter drive. Since the voltage can be varied along with frequency, these electronic motor drives are sometimes called Variable Voltage Variable Frequency drives.

Variable Frequency Drives help save energy and very useful in electronic devices. Now let me tell you that how variable frequency drives do this. It works like a switch in electronic equipments that ultimately control the voltage or frequency of electronic equipment’s output power. Are you still confused? Let me explain you how it functions? Generally, without frequency drive when induction motors draw many times when initially it comes in contact with heavy voltage at the time of starting device. At the time when the load of the device increases the torque drop and rise to pick a speed and then device reaches the full speed with acceleration where as during this process, current remains high. However, with it the action is totally opposite. When it is used in a motor and when it starts, it asserts very low application voltage and frequency which lead to minimum inflow of current.

Most people need a little help when it comes to searching for, selecting and purchasing a VFD. There are so many different attributes to consider, it can be overwhelming. We offer you the best variable frequency drives,for more information visit www.invt.com.

VFDs are electronic motor drives that allow the user to control the rotational speed of alternating current electric motors. VFD’s control the motor by varying the frequency of the electrical power supplied to the motor. A VFD can have many applications, i.e.; controlling the speed, torque, direction and horsepower of a motor.

Variable Frequency Drives have a wide variety of uses. To help increase efficiency in manufacturing facilities (by controlling the optimum speed at which the conveyors, pumps and machines all work together);To save energy in heating/cooling large buildings (by precisely controlling air flow in the ventilation systems);To keep riders safe on roller-coasters (VFD’s control the speed at which the cars travel around sharp corners and loops). The device also saves an individual to pay high electricity bills as it allows reducing the power consumption with the use of Insulated Gate Bipolar Transistor (IGBT). The use of this transistor controls the voltage and frequency of the output power. These drives are used in many mechanical applications but the most common use is in stamping machines, cranes, lifts, hoists, and automation applications of the industry.

VFD’s actually have many different names. They are known as Variable Frequency Drives (VFD), Adjustable Frequency Drive (AFD), Variable Speed Drive (VSD), Adjustable Speed Drive (ASD), Frequency Drive, A C Drive, Microdrive or Inverter Drive. Since the voltage can be varied along with frequency, these electronic motor drives are sometimes called VVVF (Variable Voltage Variable Frequency) drives.
