81. Turning To Integrated Driver Electronics For BLDCs 2/28/2020

    Despite advantages, brushless DC motors (BLDCs) have presented their own challenges in terms of technology, design, and capabilities. Typically, complex and bulky cabling has been required between motor and amplifier to attach discrete logic components “outside” the motor frame. With the latest advances in driver electronics that now can be integrated directly into brushless motor designs, BLDCs are evolving rapidly to become faster, smaller, more versatile, more controllable and more cost-effective.

82. Reasons For Turning To Slotless Technology 2/28/2020

    Brushless motors have gained greater acceptance in industry for a wider range of applications previously dominated by brush commutated products. At the same time, manufacturers have further sought to challenge conventional wisdom by improving brushless motor design. 

83. Brush DC Motors Turning More Advanced 2/28/2020

    Motor designs have incorporated new components in new ways to help extend motor life, and new or improved materials have been tapped to promote motor quality and output. Current and future brush commutated DC motors continue to move in highly advanced directions.

84. Customization To Suppress Electromagnetic Interference In DC Motors 2/28/2020

    A variety of active and passive approaches can be adopted to reduce electromagnetic interference (EMI) in systems that rely on precision motion control. The challenges are to maintain system integrity and DC motor performance without adding significant cost or weight to a subassembly.

85. Cartridge Brush Design For DC Motors And Gearmotors 2/28/2020

    The traditional method for mounting copper or silver graphite brushes in brush commutated DC motor and gearmotor assemblies has been to solder the brushes onto standard cantilever springs to enable the required constant contact with the commutator. However, this conventional spring design carries inherent drawbacks that can be overcome by housing the brushes within a specially designed cartridge and utilizing torsion springs to ensure desired even force over the life of a motor.

86. Prototype Tooling Can Help Avoid Product Launch Delays And Cost Overruns 11/19/2019

    The process for launching a product with an injection-molded component has continuously developed over decades. Prototype tooling plays an important role in this process.

87. 3-D Printing Creates Big Innovation From Tiny Parts For Medtech Firm 11/5/2019

    Many new health care technologies have advanced over the past decade to enable doctors to perform more procedures in their offices over hospital only settings. However, hysteroscopy — used to identify or treat problems of the uterus — has been slower to respond to this shift. 

88. Medtech Startup Smells Success With Additive Manufacturing 10/28/2019

    Combining the sense of smell with rapidly evolving virtual reality (VR) technology — enabling medical applications, including those that help soldiers with post-traumatic stress disorder (PTSD) — is the mission of OVR Technology, a startup in Burlington, Vt.

89. Part Marking Using Pad Printing And Laser Engraving 9/23/2019

    When designing parts for injection molding, you may need to consider finishing options, which can help improve a part’s mechanical properties, enhance surface finishes, facilitate the final assembly process, or just further customize your part or parts.

90. Don't Let A Shrinking Supply Chain Hinder Innovation 9/12/2019

    Many medical device companies are shrinking their supply bases, causing innovation challenges. This article explores some of the challenges medical device companies face in selecting their long-term supply chain partners and what characteristics those partners should have.
