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.

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.
