DC Motors for Missile Fin Actuation Systems
Missile systems require precision control to navigate and intercept targets while being exposed to extreme environments, including wide temperature ranges and heavy vibrations. Within the larger missile system is the missile fin actuation system, which oversees the movement and positioning of the missile fins (also known as control fins) in response to the steering commands from the flight computer. Miniaturized, lightweight technologies are essential to improving the maneuverability of these mission-critical systems, as when a missile is launched, these control fins position the trajectory of the missile towards the intended target.

Dedicated Brushless DC Geared Motor for Pruning Shears Applications
Pruning is the most manual and time-consuming job in the viticulture and horticulture industries. When operator fatigue impacts productivity, efficient power hand tools are the solution to save time and ensure productivity levels are maintained. When compared to manual pruning tools, light and powerful motorized pruning shears help to reduce fatigue and repetitive motion injuries in many contexts such as viticulture, orchard and tree pruning, arboriculture and tree maintenance.

Motor Technology Options for Handheld Electronic Pipettes
Pipettes are essential laboratory tools that facilitate the transfer of liquid samples from one test receptacle to another. Though pipettes have existed for over a century, modern-day iterations share little with older designs; this is largely due to the shifting nature of laboratory procedures towards utilizing motorized tools and equipment. The inclusion of miniature electric motors within the pipette is an excellent example of this trend.
The Importance of Safety and Quality When Selecting a Motion Supplier
Selecting a miniature motor provider for your device or application isn’t a simple task. Whether it’s ensuring that the potential supplier has an extensive product and technology portfolio, investigating the availability of Engineer-to-Engineer collaboration, or evaluating their reputation and global presence, there are many items to assess before making the final decision. Another factor paramount to the decision-making process is the supplier’s focus on safety and quality regarding their products, employees, and business approaches.

Estimate Brush DC Motor Reliability With Confidence
When it comes to manufacturing advanced medical instruments, reliability is a critically important consideration for coreless miniature DC motors. To estimate a motor’s expected lifetime, manufacturers employ reliability tests to measure a motor’s survivability against typical stresses like torque, speed, temperatures and vibration. Because it can take months or years to test a motor’s resistance to these conditions, accelerated life testing (ALT) over an abbreviated schedule is often the most practical testing approach.

Meet AREBO, a Collaboration of Innovation
Though small in stature, mini motors are mighty in impact! The role that miniature motors play in powering critical applications across the globe is large, especially in the development devices and applications within the medical industry. As a leading provider of mini motors, we continually strive to live our value of saving, improving, and enhancing lives by not only developing miniature motion solutions for medical needs, but by working with universities across the globe to develop new, innovative technologies. This investment in our collective future is personified by Portescap’s CSR (corporate social responsibility) partnership with the Indian Institute of Technology, Madras (IIT Madras), a leading educational institution in India.
The Benefits of Engineer-to-Engineer Collaboration in the Motion Control Industry
When you’re designing a device that requires a miniature motor, selecting a trusted and reputable motion control provider is absolutely crucial. One of the key qualifications to look for while vetting these suppliers is a focus on engineer-to-engineer (or E to E) collaboration! As its name would suggest, engineer-to-engineer collaboration is a process in which engineers representing both the motion supplier and the customer team up to actively design and develop the device, working together through the entire ideation to implementation process.
Motion System Options for HVAC Gas Valve Actuators
In HVAC systems that provide heat for enclosed spaces, gas and liquid flow must be controlled and metered accurately using sensing and modulating elements such as flow control valves or isolation valves. Some control valves are opened and closed manually at the valve stem, while electronic valves incorporate an actuator to move the stem with control from a motor and drive system. Designers have three motor types to choose from, depending on the application requirements. Here’s a summary of the motion system options:
brushed DC motors,
electric damper actuators,
gas and liquid flow,
linear stepper motors,
HVAC gas valve actuators,
closed loop positioning
Motion System Selection Considerations for Wheeled Robots
As robots become an integral part of our lives in both industry and in our homes, wheeled robots will be at the forefront of the progression. Their motion systems usually consist of brushed or brushless DC motors coupled with compact planetary gearboxes. When selecting a motor and gearbox, you will need to determine both the product’s operating and maximum conditions and confirm the required speed and torque experienced at the wheel output. Here are some tips to consider to help with your selections:
brushless DC motor,
high torque density,
motor and gearbox,

Tips to Avoid Stepper Motor Resonance Problems
When an application requires a reliable, low-cost motor with simple operation, stepper motors can be hard to beat. They can be driven step by step without needing an encoder or Hall sensor for rotor position feedback. However, the same straightforward design and driving method that makes stepper motors popular can lead to resonance problems in certain conditions.

Understand What Factors Influence the Stall Torque of a Brushless DC Motor
Apply sufficient power to a brushless DC (BLDC) motor, and it turns. Remove the power, and it stops. But there is a condition in between where power is applied but the motor is not moving. This is a motor that is at stall. In this state, with power applied, it is very much a live motor; just because it isn’t turning doesn’t mean current isn’t flowing through the windings - actually just the opposite. At stall, an excess of current is flowing, heating up the motor coils; if stall conditions are maintained, or frequently repeated, these stresses can quickly add up to trouble.

Key Concepts For Running a Brushed DC Motor as a Generator
Although design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, many tend to avoid running a brushed DC motor in generating mode because they believe this strategy is inefficient compared with motor use. Unfortunately, by avoiding using brushed DC motors as a generator, engineers pass up a number of benefits.
