Wave springs basics video: Spring force, work height, materials, and installations

Within mechanical designs, tension, compression, and torsion springs take numerous forms to store and release energy. Wave springs are a type of compression springs made of flat wire. They are called wave springs because they have multiple waves per turn. The flat wire, along with the multiple waves per turn, combine to create the same […]

Retaining ring basics video: Stamped, eared, e-clip, and constant section

As with other joining hardware (such as cotter pins, screws, and bolts) retaining rings prevent mating components from excessive moving. In short, they create a removable shoulder preventing components from migrating out of proper position during operation. Retaining rings are thin, circular, metal components that can be either stamped from a sheet or coiled from […]

What is modulo positioning?

In motion control, there are typically two types of positioning that can be used for a linear or rotary axis: relative, in which each position is based on a previous position, regardless of the actual position of the axis; or absolute, in which each position is referenced to a home, or zero, point. Axes that […]

What is a linear rotary servomotor?

While it may sound like a contradiction (or someone not knowing what they’re talking about), linear rotary motors are in fact real products. Basically, a linear rotary servomotor is a unique type of motor that offers motion in more than one direction or axis. So they can offer rotational motion like a traditional rotary motor, […]

How do I determine what gear ratio I need for my servo system?

The load-to-motor inertia ratio is a critical parameter in servo motor sizing and performance. As we discussed in a previous article, one of the most significant effects of using a gearbox in a servo system is its ability to help optimize the inertia ratio. Why inertia ratio is important If the motor inertia is too […]

How does cabling contribute to servomotor electrical noise problems?

The sources of electrical noise can be varied, but one of the most common sources is from the high-frequency signals generated by variable frequency drives (VFDs.) This noise, called electromagnetic interference (EMI), can be picked up through cabling. Cables themselves can be manufactured with special shielding to guard against EMI issues. The purpose of cable […]

When are worm gears self-locking, and where is this useful?

Worm gears are often used for their ability to provide large speed reduction and high torque multiplication. But their self-locking properties can also be beneficial in many applications.  In a worm gear assembly, the worm is typically the driving component. Self-locking means that the gear cannot drive the worm. In other words, back driving is […]

Video: ElectroCraft LRPX 22 and 32 gearmotors have operating ranges optimized to the subcomponents

In a recent video on new ElectroCraft motors, my colleague Paul Heney and I got to review integrated offerings that let designers get higher torque even while maintaining efficiency. The LRPX units are sold as gear motors — not as motor with added gearboxes. This means motor performance is optimized for gear input limitations. An eight-pole […]
