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:

Customized and Reliable Stepper Motors Address HVAC Damper Application Extremes
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:

Choosing a Motor for Electronic Pipettes
When it comes to dispensing a specific volume of liquid in a lab environment, pipettes are essential. Electronic air displacement pipettes have taken the lead due to the needfor a high level of precision and accuracy required for repeated use over a periodof time. With the improvement of a digital interface for adjusting aspiration or dispensing, electronic pipettes offer a huge advantage and relief from ergonomic methods.
The motor is the key element in the design. When design engineers specify a motor they must consider factors such as motor power, size and weight, and control electronics. Let’s look at the two most considered motor options - stepper motors and DC motors to help determine the fit for your application.

Motor Innovations: Differential Compact Drives
What is the need for new gearing technologies?
Miniature motion technology demands flexibility as well as compactness with higher power and efficiency. Conventional gear technologies have some limitations which restricts the development of new concepts. One such new concept is a “Differential Compact Drive” which differentiates with other concepts in such that it provides high reduction, high efficiency, lower noise, and a compact length gearbox. Before reviewing the advantages of this new concept lets first review the limitations of Conventional Planetary systems.
