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.

If you have to regulate HVAC system airflow on a constant basis, you’ll need automatic dampers with electric or pneumatic motors that can be controlled by a thermostat or building automation system. When designing an external mount electric damper actuator for an HVAC system, it’s important to review considerations in order to create the best motor-damper combination.
When evaluating a miniature motor to pair with an actuator, keep in mind that it may need to be customized. Ask yourself the following questions:

Sterilizable Encoders and BLDC Motors Drive Surgical Hand Tool Advances
As handheld surgical tools gain wider adoption, there’s a growing demand for smaller, lightweight devices that can offer more capability and precise motion profiles. When it comes to brushless DC motors (BLDC) commonly used in handheld surgical tools, magnetic encoders provide the high-resolution feedback that makes high-performance drive systems possible, and they offer many benefits. However, not all encoder/feedback technologies are the same. Here are some situations that call for an encoder as part of a drive system:

Many applications today have critical space constraints and require flat motor solutions. However it is not always obvious what technology would work best in this type of situation while still being able to meet performance requirements. Typically, the speed-torque criteria can help provide a guide on what technology may be optimal for the given application. Let’s explore the various technologies available for flat motors depending on design requirements.

Surgeons worldwide have come to favor advanced surgical hand tools for their effectiveness and successful patient outcomes. In order to keep costs in check, these sophisticated tools are re-used many times. In between procedures, the tools require steam sterilization, or autoclaving. While Tier-I surgical centers can afford frequent re-use of premium surgical tools, this model is often too expensive for smaller-scale Tier-II and Tier-III operations. However, the right motor can allow designers to create affordable surgical tools with high quality and durability.

Today’s most challenging battery-operated tools require power, speed, and efficiency within the most ergonomic package. Studies have proven that users prefer a smaller and lighter tool with a high level of performance. The ergonomics needs have tremendously increased in the last few years to highlight operator comfort and efficiency while using battery-powered tools.
There are multiple ways to lighten the tool. For example, we recognize the battery of the tool as one of the heaviest components, therefore the trend is to reduce the battery size. Lowering the battery size will affect the number of cells and thus the voltage: The smaller the battery, the lower voltage.
Industrial power tools support the increase in productivity while remaining versatile. We achieve productivity gains thanks to faster working cycles, so the tool should deliver higher speeds. We derive versatility from an increased torque capacity.

The medical sector today mandates mechanical ventilation in cases where a patient's spontaneous ventilation is inadequate to maintain life. This is done to prevent an imminent collapse of other physiological functions, or ineffective gas exchange in the lungs. Mechanical ventilation therapies in hospitals and in the field have contributed to dramatic improvement in life expectancy of patients during and after surgeries, or patients suffering from accidental disruption of lungs, or even patients suffering from acute chronic pulmonary diseases. More recently, home care applications previously considered as luxury or comfort therapies are showing an interest in race to extend people’s life. For instance, low end mechanical ventilators devices known as CPAP are used at night to treat sleep apnea, a disorder once considered to be a simple discomfort and which is now recognized as a source of major medical complications such as increased blood pressure, diabetes, etc.
