How To Select a DC Motor Coil Based on the Required Working Point and Power Supply 

Although DC motors have a common operating principle, many applications — including portable medical devices like infusion pumps — require one that converts electrical energy to mechanical energy with the highest efficiency to achieve a long, reliable service life. This is typically where an ironless DC motor comes in.

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.

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.

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.
