Some vaccines are highly sensitive to temperature variations and must be stored at ultra-low temperatures (ULT) from the point of manufacture until just before administration to the patient. The Pfizer COVID-19 vaccine, for example, initially required super-cold storage, with temperature maintained below -60 °C (-76 °F). In the manufacturing plant and associated warehous...
HVAC systems include low cost, electronically controlled valves for fluid flow modulation and shut-off purposes, typically requiring medium torque at low speed. Motor technologies available for actuating these valves have different inherent characteristics that could be advantageous depending on the specific application requirements. INTRODUCTION HVAC systems are used t...
This article is focused on the stepper motors which is a type of brushless DC motor with a high number of poles. This technology is generally driven in open loop without any feedback sensor, meaning the current is typically applied on the phases without knowing the rotor position. The rotor moves to be aligned with the stator magnetic flux, then the current can be suppli...
While the overall R&D process for a medical device takes years, most of this timeline is absorbed by tooling and component lead times, market feedback, life testing and regulatory approval. Design engineers often have very tight windows to complete their next deliverable before the deadline. To meet early-stage deadlines, it is a common and accepted practice to design th...
To keep the cost of procedures down, the most sophisticated tools must be used in high volume which requires steam sterilization (autoclaving) between patients. High volume surgery centers (often referred to as Tier-I) can both afford the upfront cost of these premium tools and perform enough surgeries to bring the cost per patient to an affordable level. However, this e...
Due to the presence of electronic components and materials susceptible to corrosion, moisture is often a cause of premature failure, particularly for electric motors. Designers need to consider how to mitigate the effects of moisture—from saline, steam sterilization, or other contaminant sources—by preventing ingress where possible, selecting robust components, and isola...
For Fuyu, the previously produced drawings and the standardized modules with related materials can be regarded as modular products. Conversely, new designs with relatively large design changes based on existing modules can be regarded as "non-standard customization". After the non-standard technology is mature and finalized, it will be transformed into standard equipment...
Specifying the right ball screw for a given application will ensure machine accuracy, repeatability and life while minimizing the total cost of ownership. A ball screw drive translates rotational motion to linear motion or vice versa and can apply or withstand high thrust loads–upward of 750,000 lb static capacity using a Ø6.000 in. ball screw assembly–with efficiency...
The vast majority of electric motors in use today are fixed speed, fixed voltage AC induction motors. These motors consume two thirds of the total electricity used in industry. With this in mind, using a technology that could save up to 32% of energy on fixed speed induction motors should be a consideration when replacing motor starters or designing new systems.

There are many ways to build linear systems for motion in the X, Y, and/or Z directions – also known as Cartesian coordinates. The terms we generally use to refer to these systems depend on how the axes are assembled, where the load is positioned, and to some extent, what type of use the system was designed for. In many industrial applications, Cartesian and gantry-style...
The correct bearings for an application let a stepper motor run efficiently across its design speed range, minimize friction and power loss, produce little noise, and have a long service life. Motors containing roller bearings for heavy belt loads may prematurely fail when run with an in-line coupler because a minimum load is not maintained.

That smooth operating characteristic is a result of several factors, including how consistent the various parts of the coupling are assembled and held together. Maintaining precise and repeatable assemblies is more than having a good torque wrench. For example, it is possible to have several bolts that are all torqued to the same value and still have inconsistent cla...
