Actuator sizing starts with one question: how much force does the actuator need to produce to move your guide or shifting stand reliably? The answer depends on more than just the weight on the bearings. [rr] uses a 6-term force model that accounts for …
This question highlights an important distinction that causes confusion: load weight is not the same as thrust force . The RLA Series supports loads up to 30,000 lb on precision linear bearings . That is the weight sitting on the bearings — the roll, the …
Let us be direct: servo motors are excellent. They offer smooth torque delivery, high bandwidth, and precise closed-loop control. For many motion control applications, they are the right choice. The question is whether web guiding is one of those …
The factor of safety (FoS) in actuator sizing serves a specific purpose: it provides margin for forces and conditions that are not fully captured by the model . The right FoS depends on how many of those forces you have actually modeled. Simple mode — FoS …
The RLA actuator converts rotary stepper motor torque into linear thrust using a belt-driven ballscrew (or roller screw) mechanism. The conversion follows a straightforward mechanical relationship. The thrust scalar k relates motor torque to linear force: …
Bearing friction is typically the largest single force term in an actuator sizing calculation, and getting the friction coefficient right matters more than any other input. Catalog values by bearing type: Profiled linear rail (recirculating ball) — μ = …
Yes. [rr] stepper-driven actuators routinely move loads exceeding 10,000 lb — and are rated for loads up to 30,000 lb on precision linear bearings. But the answer requires context, because the question conflates two different numbers. Load weight vs. …
With our 2014 program at it’s end, we would like to thank everyone who attended our open accelerator workshops, seminars, and networking events during our 12-week program. In an effort to reach out to the local entrepreneurial community, we opened up our …
This is a fair question that deserves a fair answer. Both stepper motors and brushless DC (BLDC) motors with field-oriented control (FOC) are viable drive technologies for web guiding actuators. Each has genuine strengths, and the best choice depends on …
