Those who are working in a factory or industrial automation industry must be aware about variable frequency drives, usually called VFDs. Variable frequency drives are known for best speed control and highly useful for operational facilities. Here, CM Industry Supply Automation – VFD & Servo Drive/Servo Motor expert mention some ways that VFDs can enhance complete factory production and efficiency.
1. Less Disturbances to the Power Supply Line
When utilizing an AC motor, the early start-up puts an enormous strain on the whole power supply line. This is not applicable with a Variable Frequency Drive as the voltage begins at zero and slowly rise up from there.
Fundamentally, rather than starting with a high bang like with an AC motor, a Variable Frequency Drive slowly and progressively picks up pace to simplify the strain on the power supply line. The difference is obvious, particularly among minor equipment like computers, which can drop offline when an AC motor begins up.
2. Good Adjustments
While a Variable Frequency Drive begins at a low speed, it can be adjusted more comfortable even from a distant location. It became possible with Programmable controllers that permit operators to remotely start the Variable Frequency Drive at a lower speed while picking up in power over time. For controller’s programmable applications are very helpful for adhering factory parameters.
Adjusting torque within time become easier too. Also variable frequency drive can be set to a particular torque limit for preventing excess currents and overloading. This gives protection against overuse, allowing factories to maintain their machines and stop fast wear and tear.
3. Control of Acceleration and Deceleration
The variable frequency drive offers good control over acceleration and deceleration to the operators. While comparing with an AC motor that starts up and utilizes tons of power and energy, a Variable Frequency Drive can begin at a controlled speed and gradually accelerate from there.
This conserves the motor’s strength and efficiency and save money in the long run. As for slowing and stopping, the ability of controlling this process with a Variable Frequency Drive means that mechanical stress cut down and the longevity of machine increases.
4. Cost efficient and energy saver
VFD offer maximum energy savings. The variable torque loads cut down complete energy usage and the lower the beginning speeds. As compare to AC motor which just operate at full speed, a Variable Frequency Drive is adjustable, cut down energy consumption and lower complete costs for factory operators.
VFD offer monetary saving and could reduce the requirement for costly components such as vanes and dampers in the factories. The ability of adjusting the acceleration and stopping VFD speed can also cut down the requirement for gearboxes that can cut down on space.
Sometime, an energy provider may provide particular incentives to industrial customers who utilizes variable frequency drives. All things considered, there could be huge financial gain for those who choose Variable Frequency Drive rather than an AC motor.
Remember that there are many VFD makes and models available on the market such as Lenze VFD, KEB VFD, Siemens VFD, Yaskawa VFD, Danfoss VFD and more therefore there could be noteworthy differences in the complete quality and dependability of the drives.
Monetary savings cannot be the only factor to choose a variable frequency drive but can be a possible benefit. Hope now you feel more informed about Variable Frequency Drives advantages and how they can enhance your factory automation and processes.
Servo Motors are used every day in automated processes where exact control and positioning required along with high torque. You have already read much about servo motors on our industrial automation blogs. Its features and capabilities are always highlighted but there is little info about the Servo Motor repair and maintenance.
Servo Motors are made with same parts such as stator winding, the shaft, bearings and an end shield same like AC motors. However, the incorporation of an integral feedback device inside Servo Motors makes it quite different from AC Motors. This device become an encoder or a resolver and operate with the controller to confirm that the motor can be programmed to execute difficult tasks like accurate positioning, quick changes in speed and also maintaining a stationary position while maintaining a firm level of torque.
It is vital that the devices programming and set up is integrated into the repair procedure of Servo Motors. This can be possible by using software which is precise to the Servo Motor make and model as there are many brands like Siemens Motor, Lenze Motor, KEB Motor, Danfoss Motor, Yaskwa Motor are available in the market.

This CM Industry Supply Automation article will outline the must-know factors when looking to dimension a VFD for a drive system. You can check out the load characteristics reviews, an important element that will be find out by the end application.
Perhaps the most crucial aspects of appropriately selecting a variable frequency drive (VFD) is checking that it has adequate volume in terms of KW and minimal current rating to permit the motor to produce the essential torque right across the proposed speed range while permitting for any overload time frame.
Loads can be categorized into following types:
The three most common load characteristics are:
The very initial step to dimension a drive system comes from considering the driven machine application. Because of constant torque profiles augers - drills, screw compressors like chillers, positive displacement pumps and conveyors they are considered heavy duty for motors, which are handling loads.
While starting, motors handling applications like fans and centrifugal pumps need little overload i.e. their beginning torque is even comparatively low by comparison with some Heavy Duty applications.
Many machines such as grinders and lathes, and winders load a motor with CP (constant power) that means power remains continuous, regardless of the speed or torque.
Continuous and cyclic loads
Above three common load types can either be categorized as continuous or cyclic. When dimensioning your drive system in cyclic load as there could be likely overload repetition caused by common starting and stopping which can conceal the thermal capabilities of motor.
Many machines use an induction motor, which can work regenerative. At particular working points, the driven machine stored inertia can cause the motor to work like a generator and causes VFDs DC bus voltage to increase. If this left unchecked, it can result in the VFD tripping and the load to freewheel out of control. The regenerative applications often need installation of DBR (dynamic brake resistors) which will burn off extra regenerative energy as heat, but this solution type is not always effectual way to control regenerative energy. Also it might be the lowest up-front cost choice.
Constant torque / heavy duty (HD), Variable torque / normal duty (ND), and Constant power (CP) are three usual load handled by motors.
Each load characteristics can be any continuous or cyclic – cyclic loads can make exact challenges regarding the complete drive system performance and should be sensibly considered during the planning stages.
Applications that might be regenerative need some type of mitigation technique either in the dynamic braking resistors form or by fitting a Variable Frequency Drive with an active ‘front end’. It is something considered as the most efficient solution as they will allow regenerative current to flow back into the mains without the requiring braking resistors connection.
