There's more to selecting a motor than meets the eye. Motors typically are grouped into three categories. General-purpose motors are designed around industry standards and feature standard operating ...

Multidisciplinary engineering systems are complex andcarry increased risk, development time, and integrationchallenges. Model-based system design helpsto manage complexity, enhance integration, and ...

Finding the right motor is one of the core elements in the selection of dynamic drive components. Due to their high starting torque maxon DC motors with or without brushes are the perfect matches for ...

DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

Often, an HVAC system is designed by the selection of individual components and not by a whole-system approach. This has become common practice for mechanical engineers, usually resulting in poor ...

A recent project brought to light some new motor-selection tools that saved a lot of time and effort. This particular project needed a motor for a linear-drive system that used a leadscrew. Time to ...

Frequently, when it comes to step motor selection, users will select a motor with the highest holding torque rating, assuming that it will give them optimal performance. However, it is an improper ...
