Symbol Glossary Definitions. Linear Voice Coil Motors - Actuators and micro voice coil actuators. Linear DC Motors, Voice Coil Motors (VCM) or Voice Coil Actuators (VCA) are the simplest type of electric motors.
These motors consist of two separate parts; the magnetic housing and the coil. Applying a voltage across the terminals of the motor causes the motor to move to one direction. Reversing the polarity of the applied voltage will move the motor to the opposite direction. The generated force is proportional to the current that flows through the motor coil. This force is almost constant in the specified stroke range of the motor.
Voice coil motors are brushless and do not utilize commutation. The non-commutated motor construction increases reliability. Very high speeds and accelerations can be easily achieved. The moving part needs to be supported by a mechanism supplied by the customer. ThinGap high power density brushless motors. ThinGap’s brushless DC, ring motor architecture allows for creative solutions for Optical designs by allowing critical parts of the system, such as lenses, to be integrated into the center of the motor.
Our standard motors have IDs from 25mm to 200mm and custom motors can be made larger. Our “True-Zero ™”zero-cogging torque motors, coupled a high resolution encoder and precision bearings, offers a level of smoothness and precision not previously obtainable. This integrated design reduces parts count, weight, and ultimately cost.

These include but are not limited to environmental stresses, EMI shielding, and maintenance requirements. Additionally, the advanced technological requirements of the devices requiring these enclosures mean that these devices must be more rugged and more powerful, as well as smaller, lighter, and easier to replace. This poses challenges for designers, leading them not only to suppliers who can meet these requirements but partners who can assist in the design and supply chain management of these complex units.
For environmentally-sealed and EMI-shielded electronics devices, there is no better full-system solution than an overmolded or vulcanized cover. So, what is overmolding/vulcanizing/mold-in-place gasket anyway? 6 Benefits of Overmolded Covers for Aerospace and Defense Applications. Choosing the right type of seals - SurfaceID. When it comes to choosing the right seal type for a product, there are a few critical questions that should first be answered to avoid malfunctions.
Depending on the particular seal’s application, an incorrectly chosen seal can result in poor performing products, costly defects and even serious injuries.

Medical Device Sealing Solutions -- What Designers and Manufacturers Need To Know, Avoid And Consider When Planning Seals In A Device Seals are one of the most important components in many medical devices.
While small in cost, seals have a profound affect on the function of a medical device and the outcome of a medical procedure. Engineered sealing solutions have advanced to meet the new medical device designs due both to new materials and to new processes for producing these seals. An understanding of the fundamentals of seal design, the tools available to assist in the manufacturing process and pitfalls to avoid will help in achieving a successful seal and medical device outcome. Classifying the three basic seal designs New advances in trocar designs incorporating specialized seals allow multiple instruments to be inserted in the single trocar.
When approaching a new seal design, It is important to classify the seal based on its intended function. Nylon Chemical Compatibility Chart. What Chemicals are Compatible with Nylon?
