Electric motors are used in a variety of industrial applications, to provide mechanical energy to run power tools, fans, electric vehicles, etc. These motors operate on the basis of the electromagnetism principle, which states that: if a current-carrying conductor is placed in a magnetic field, it experiences a mechanical force caused by the attractive and repulsive forces created by the magnetic field. The magnitude of the mechanical force may be obtained as a product of the magnetic field, the current in the conductor, and the length of the coil in the motor. While the direction of motion of the conductor can be determined by Flemings left-hand rule...
Have you ever wondered how forming and metal cutting machines provide precise motion for lathes, bending for metal fabrication and milling or how a robotic vehicle mainly used in military applications with bomb detection systems is controlled, or how antenna positioning systems control the precision in elevation and azimuth? Well, a servo motor is at the heart of these precise position and motion control systems. A servo motor is a compact electrical component, which rotates parts of a machine with great precision and high efficiency. Its output shaft can be moved to a particular position, velocity, and angle which is not possible with a regular motor. This is because the servo motor utilizes a regular motor which is coupled to a sensor for feedback. An encoder is used as the feedback sensor, providing position and speed feedback. It achieves this by observing the change of position, mechanical motion, rate, and signals to the controller. The encoder also receives control signals from...

Industries globally understand the importance of electric drives in ensuring efficient control of motor outputs. And with the constant developments and innovations springing up in the industrial automation field, the need for alternating current (AC) and direct current (DC) drives have continued to grow in leaps. Both AC and DC drives are indispensable to the regulation of control signals. However, there are notable differences between the two drives. This article focuses on these differences in terms of benefits, composition, operation, capability, cost, and usability. The AC Drive and its Benefits The AC drive is used to control motor speed through the conversion of direct current (DC) to alternating current (AC). This drive involves such components as an inverter unit, DC circuit, rectifier unit, etc. It has helped increase productivity and innovation in the electronics industry. AC drives operate only with motors whose speeds are controlled by switching frequency from the...
Servo drives are an integral part of a servo system. Working in tandem with a motor, controller, and a feedback device, servo drives receive instructions from the controller for the prescribed motion for the motor. It then sends the right amount of electrical current to enable the motor to perform the motion required. There are several types of servo drives including those that control torque as well as velocity and positioning. But torque is the most used variable in many servo systems. Because they deliver the precise required voltage and current to motors, servo drives are also called amplifiers. All variables encountered by service systems – torque, position, velocity – are part of a complex motion control system that impacts safety, efficiency, and equipment condition. So, having the right servo system components are critical. Without the right components, servo systems could overheat and shorten the lifespan of the motor. There are many OEM producers of servo drives across the...
Variable Frequency Drives (VFD) and Soft Starters are electronic devices that are popularly used in a wide variety of industrial processes which require the utilization of AC motors. These devices share a common, specific purpose to which they are applied, particularly in the field of motor protection and lowering of energy consumption. But what is the difference between a VFD and a Soft Starter? Before we differentiate the difference between each of the devices, let us understand first the common industry terms used to refer to these devices. A Soft Starter is commonly termed as Soft Starter, Motor Starter, or simply starter. A VFD is popularly termed as Variable Speed Drive (VSD), Adjustable Frequency AC Drive, Adjustable Speed Drive, or simply an Inverter. Soft Starters are generally used to protect the AC motor from the stress produced by a large amount of electrical inrush when the motor is started or stopped. During start-up, high amount of inrush current is absorbed directly by...
Today’s motion control systems require motors that do many different things, such as precise positioning or controlled torque. Servo motors allow for better control of these conditions by allowing a high rpm spin at low torque yet slowing down and increasing torque as states require. With position sensors, encoders, and gearing, microcontrollers can sense the actual versus the desired position and correct it to allow rotors to turn to the machine gear or wheel to the precise position required. These DC motors can be either positional, where precise rotor control is needed, or continuous, turning clockwise or counterclockwise at different programmed speeds. Servo motors are available in numerous sizes, and torque ranges and cost-effective to achieve control in high torque situations. They are best suited for speeds over 2000 rpm where high torque is needed. However, they are limited in positional rotation to 180 degrees. Allen-Bradley has a long history of quality, durable, and robust...
As factories and warehouses have become more connected to platforms for control and analysis of operating and production environments, equipment manufacturers have created OEM equipment to operate with more precision. This means that more than ever, reliable and efficient control of motor speed and performance is critical. When control systems require more than just stop and start or on and off applications, variable frequency drives (VFD) can be used to deliver the right amount of voltage and frequency to a motor so that it not only does what it is required to do, it also does so with precision and safety for both operators and equipment. Because using VFDs allows full control of operating motors, companies can reduce both cost and energy consumption while achieving very tight process control for their operation. Allen Bradley Low Voltage VFDs Allen Bradley’s VFD solutions cover a wide range of sizes and applications for any control and automation needs through its PowerFlex® VFD...
Motion control sits at the heart of most manufacturing and warehousing applications. With accurate motion control, system designers can create closed loop, efficient systems that optimize performance across a wide range of industries. One common requirement for many systems is for low inertia servo motors. Depending on the final product or application, low inertia servo motors are used in a variety of applications. These applications range from packaging and converting where consistent, high speed high torque requirements drive the value of the system. They are also used for electronics assembly, as well as in big ticket items such as automotive and metal forming where consistent performance and reliability are key. The Value of Low Inertia Motors Simply stated, low inertia motors are small and have a small spindle inertia. In high volume environments when the motor is operated almost continuously, a low inertia motor will impart both low inertia and heat to the system. In systems...
