1 Safety Elements for Mechanical Torque Limiters (June 2010)

The world of high horsepower drives often calls for mechanical design to be approached from different perspectives. As motors, gearboxes and machines increase in size, power density can become disproportionate from one driveline component to the next, emphasizing the need for more rugged, robust and compact equipment.

3 The Importance of Thermal Protection for Torque Motors (August 2015)

When talking about high-end machining or manufacturing applications that include direct-drive technology, one of the key advantages of utilizing this particular transmission method is its endurance. Because of the very nature of direct-drive motors they are able to operate at peak performance levels indefinitely — without any kind of wear or aging — as long as the motor isn’t pushed past its capacity. Unfortunately, because this isn’t a perfect world, unexpected things can happen which can cause the motor to overheat. Whether the heat source is due to a parameter being input incorrectly, or an unexpected external force causing more resistance than expected — it is important to have certain forms of thermal protection in place. Since torque motors are built in such a way that they cannot be repaired and yet maintain their efficiency, it is vital to prevent any overheating — thus precluding the need to purchase a new one.

5 Baldor Basics: Understanding Torque (April 2017)

In the process of applying industrial drive products, we occasionally are misled into believing that we are applying horsepower. The real driving force is not horsepower - it is torque. This paper is developed to impart a deeper understanding of torque, its relationship to horsepower, and the types of loads we most frequently encounter.

6 Why Direct Drive (March 2017)

In today's highly competitive world, the better someone understands the advantages and benefits of direct drive technology, then the more they will have an advantage in machine building, giving them an edge over their competition.

8 Cut and Print (December 2011)

Norkol Converting Corporation is one of the nation’s leading independently owned converters and distributors of commercial printing papers. The company has full production capabilities and state-of-the-art machinery for winding, trimming and sheeting. The company utilizes traditional slitter re-wind equipment that unwinds, slits and then re-winds paper to new dimensions. These conventional re-winders, while typically producing new widths of paper with clean cuts, work at an inefficient, slow pace.

9 Torque Arm Design Considerations for Shaft-Mounted Speed Reducers (April 2008)

Most manufacturers of shaft-mounted speed reducers offer torque arms for their products. However, in some situations, a machine designer may be required to design his own.

10 Troubleshooting with Torque Transmission (February 2008)

The issue might be a faulty treadmill at a local gym, the need to update orthopedic surgery equipment or simply a train stuck in neutral at the toy store. Whatever the case may be, viewing e-mails in the marketing department at Torque Transmission is like opening Christmas presents every morning.

11 The Case for Hollow-Shaft Torque Motors (August 2010)

Permanent-magnet, synchronous-torque motors offer significant advantages on high-energy-consuming and high-dynamic applications.
