Servo Motor Application: Glass Manufacturing

A leading glass product manufacturer designed and built a shearing distribution system that is used to precisely measure and shear specific amounts of molten glass for a finished high-quality glass component. The original design of the equipment employed a hydraulically actuated shearing mechanism that was not accurate enough to cut consistent amounts of molten glass, particularly with a capacity increase that was needed by the customer.

Torque Systems was chosen to design a servomotor that could drive a blade to precisely shear the molten glass and operate in a 100°C environment for 45,000 hours before maintenance. The result: a specialty servomotor that enables the manufacturer to produce consistent, high-quality glass components with significant reductions in operating costs.

Servo Motor Application: Military & Communications

The U.S. Military's early detection system includes a series of 18 meter diameter parabolic antennae located in a very harsh environment; one that exposes them to winds of up to 130 Kph. Winds this strong are capable of pushing the large dish antennae and causing control problems with the azimuth drive servomotor which, in turn, demagnetize the permanent magnets and reduce the motor torque.

Torque Systems solved the problem by customizing an industrial brush platform motor design, which includes a tachogenerator and an integral magnet-charging circuit to recharge the magnets after peak torque conditions are encountered. The Torque Systems self-magnetizing servomotors provide for accurate, fail-safe continuous positioning of the parabolic antennae that are part of the U.S. Military's critical early detection system.

Gantry Servo Motor Application

Product Overview

A manufacturer of non-destructive testing systems for the aerospace, railroad, auto, ordinance and tubular industries required a customized solution on their gantry systems

When their previous supplier was unresponsive, they asked ITT-Torque Systems if we could provide a solution. They were instantly impressed with the responsiveness of our sales and engineering teams. Our sales team worked to understand the challenges within their application, and our engineering team worked to design the best solution for them.

Product Overview

It was determined that the solution for them would require some customization of our existing 140mm MDM- 5000 brushless motor. We were able to customize the connector wiring and mounting to make sure we provided a solution that met the needs of their application to synchronize positioning on both the horizontal and vertical axis.

Today, our motors are used on all their gantry applications that require smooth, precise motion to drive their sensor for material inspection. They still receive the same responsiveness, quality, performance and support today as they did when the initial discussions began. For these reasons, ITT-Torque Systems is their motor of choice.

BNL 2310 Brushless Servomotor Improves Wire Bonder Performance

Product Overview

A leading OEM of wire bonding equipment for the semiconductor industry had been producing various models for several years. For many of these years, a competitive brushless servomotor was used to power the precision motion needed in the equipment. The wire bonder manufacturer began to have problems with product support and availability because the motor manufacturer had decided to discontinue the servomotor model.

The wire bonder manufacturer needed to replace the discontinued motors with a minimum of changes to his product. A robust, yet economical motor that matched speed, torque and mechanical fit was required.

Product Solution

The solution was the Torque Systems BNL 2310. To meet customer specified speed and torque requirements, a matched winding BNL 2310 was proposed. Since the need was urgent, a number of standard winding prototypes were tested by the OEM. They not only met the performance requirements, but actually improved the performance of the wire bonder due to better acceleration capability over the old servomotors.

The customer quickly decided to specify the standard winding BNL 2310 servomotors into his equipment.Torque Systems also customized the shaft and motor mounting plate to the exact specifications of the customer. The capability of the BNL2310 enabled the customer to improve the wire bonder performance without redesiging to fit an “off the shelf”motor.

Application Opportunity

The end result was a smooth transition to improved performance in a high quality wire bonder without gaps in product support or availability.

Glass Maker Sees A Clear Opportunity for Improvement

Product Overview

A leading glass product manufacturer designed and built a shearing distribution system that was used to precisely measure and shear specific amounts of molten glass for a finished glass component. The original design of the equipment employed a hydraulically actuated shearing mechanism that was not accurate enough to cut consistent amounts of molten glass to produce high quality glass components.

This problem became even more evident when the customer increased the throughput capacity of the shearing system. The hydraulic system was also subject to fluid leakage and too frequent failures, causing maintenance headaches and unacceptable downtime.

Product Solution

The manufacturer selected Torque Systems to solve their problem.Application requirements were extreme: The servomotor must drive a blade to precisely shear the molten glass and operate with an extensive mean time between failure. It must operate in a 100°C environment for 45000 hours before maintenance. It must also fit into a predefined envelope because it was to beretrofitableinto existing shearing distribution systems.

The solution was a “clean sheet design”to meet the difficult requirements. Torque Systems developed custom electro-magnetics for this application. The design took advantage of advanced material technology and custom windings to produce a very high torque density brushless motor. A custom cooling arrangement, shaft and mounting configuration was also designed in. The result: A specialty servomotor that could reliably operate in, and physically fit into the harsh environmental conditions of the shearing distribution system so that the manufacturer could produce consistent, high quality glass components with significant improvements in operating cost.

Platform 2100 Brush Servo Motor Provides a Superior Measure of Success

A Torque Systems proprietary low cogging feature was designed into the 2100 Series standard platform motor to provide smooth, slow speed operation during acceleration and deceleration a critical performance enhancement to ensure the measuring instrument’s precision and accuracy.

Torque Systems also provided customized interfacing with their equipment. The customer specified a metric mounting plate and equipment specific connectors and cables. These features enabled the customer to maintain their optimum design without compromising to fit an “off the shelf”motor.

The end result was a not only a highly precise and accurate machine, but the support of the manufacturer’s excellent reputation with the customers that they serve.

MS65 Linear Actuators Keeps Choppers Afloat

Product Overview

A specialty manufacturer of helicopter flotation devices recently improved an emergency flotation system for land based helicopters that fly over water. Land based helicopters are typically not equipped with floats that allow them to land on water, so they must seek hard ground for emergency landing.

The float manufacturer saw a unique opportunity to provide an improved system for inflating floatation devices that could be used on them in just such a situation. The new float design employed a safe and reliable means of inflation to ensure safe water landing. Until now, typical inflation systems employed either an explosive device or mechanical means for initiation.

Product Solution

A compact, electromechanical system with servomotor and actuator was used to operate a compressed air valve for float inflation in the new system. Torque Systems’MS 65 was the perfect choice for this part of the system due toit’s uniquely small, yet robust configuration. The MS 65 was selected for initial test and proved to be a reliable solution for the manufacturer, and is now being supplied in these new emergency flotation units.

MS 800 Gets Your TV Dinner Right!

Product Overview

A major manufacturer of food processing and packaging equipment developed a new product designed to insert different food portions into compartmentalized plastic trays prior to freezing. The key feature of the machine was the high throughput it could achieve. Initially, the design of this machinery included a hydraulic pump and cylinder system to move the “TV Dinner”trays into position.

After testing the equipment with the hydraulic system, the manufacturer discovered that this system could not achieve the accuracy and speed required to get each food portion into its proper compartment. A faster and more accurate positioning system was needed to keep the peas out of the mashed potatoes, and the mashed potatoes out of the Salisbury steak.

Product Solution

Torque Systems provided the answer. A totally unique, fully food grade, IP 66 sealed linear actuator system, complete with brushless servomotors was developed for the application. Twelve MS 800 food grade actuators on the machine provided high speed, accurate positioning of the trays. Proper insertion of the food portions into their respective compartments was achieved without mishap. The machine manufacturer was delighted with the results, as this step in the packaging process was key to the overall commercial success of the food packaging machine.
