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 ...

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 ...

Motor selection is often a complicated process that takes a lot of work with various vendors. Groschopp engineers share knowledge and expertise about the motor selection process. Focusing on four ...

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 ...

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 ...

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 ...

While software and other advanced technologies often capture the automation technology spotlight, the fact remains that not much happens in the manufacturing or processing industries without motors.

The electromotor, which is sometimes called motor or dynamo, is responsible for creating the mechanical force necessary to rotate the fan in the cooling tower. In other words, the fan or impeller of ...

Parameters that define a motor type are the mechanical output power, the shaft bearing system, the commutation system used, and the possible combinations with gearheads and sensors. The most important ...

The purpose of an electric motor is to convert electrical energy to mechanical energy in the form of rotational force. Just about anywhere that machinery is required to create movement, the chances ...
