Motor Technology Selection: Evaluation Factors

Motors are usually an indispensable element of an application’s motion system. However, selecting the motor is rarely straightforward. Motor technologies all have characteristics that can impact a design in different ways, and  will determine whether you choose a brushless DC, coreless DC or stepper motor. Here are some key considerations to help you choose an optimal motor for your application.

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:

Improve Thermal Performance for Ironless Brush DC and Brushless DC Motors

Improve Thermal Performance for Ironless Brush DC and Brushless DC Motors

Electric motor manufacturers must ensure that a motor’s instant internal temperature never exceeds its various components’ maximum allowable temperature. Depending on the design of the motor and the materials used, thermal phenomena will dictate the motor’s performance. Motor designers typically have two options to enhance motor performance without overheating and damaging its components: increase power conversion efficiency by generating less heat for a given mechanical power output or improve the motor's cooling capability through heat dissipation.

Advantages of Gearheads: What to Choose and Why

Advantages of Gearheads:  What to Choose and Why

We know that the purpose of a motor is to provide a certain amount of power to produce a specified amount of speed and torque. In applications requiring a large torque load at slow speeds, it is more economical to use a gear motor (aka gearhead) rather than a large enough motor to provide the specified torque. The gearhead  is mounted on the front end of the motor and specific gearing provides the overall speed and output torque. There are various types of gearhead technologies. Here, we will focus on Spur compound and Planetary.   Spur gears are designed with the concept of having only one transmission point per train.

A Case Study for Infusion Systems: Coreless Brush DC Motor Controls Nutrient Flow for Medical Feeding Pumps

Enteral feeding pumps are medical devices with a built-in tube used to deliver nutrients directly to the stomach of patients who are unable to safely consume food by mouth. The motor systems in these small, lightweight devices must also deliver sufficient torque to ensure continuous flow. The pumps also must be able to adjust flow rates — depending on the nutrition formula and patient needs — with accuracy and precision.

Role of Tribology in Performance of Miniaturized Electrical Motors

Role of Tribology in Performance of Miniaturized Electrical Motors

Tribology is the multi-disciplinary subject that deals with wear and friction of the surfaces in motion. Miniaturized electrical motors contain tribological components like sliding contacts (brushes), rolling contacts (ball bearings and bush bearings), damping rings, seals, washers and gears. These tribological components tend to fail before other components of the motor mainly because of friction and wear. Thus, life of the motor is very much dependent on the performance of the tribological components. Let’s look at a few tribological motor components which impact overall life.

Choosing a Motor for Electronic Pipettes

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.
