Single-phase, two-phase and three-phase motors: all you need to know

motores monofásicos, bifásicos y trifásicos

Electric motors let us obtain mechanical energy in the simplest and most efficient manner. Depending on the number of supply phases, we can find single-phase, two-phase and three-phase motors with coiled startup winding and with coiled startup winding with a capacitor. And choosing one or the other will depend on the necessary power.

If you are involved in a project and don’t know what type of motor you should use, this post will interest you! In it, we tell you about each motor and their differences. Let’s get to it!

Linear vs. rotary actuators

actuadores lineales o rotativos

Thanks to technological advances and the onset of the automation era, human-powered devices increasingly became a thing of the past, giving way to their automation through the use of actuators. With the purpose of improving people’s wellbeing and comfort, today linear and rotary actuators are widespread and on high demand, but before taking a closer look at them, we will give you an overview on what an actuator is and the different types in existence. Let’s get to it!

What are plain bearings and how do they work?

cojinetes de fricción

Plain bearings are mechanical components charged with bearing a load and allowing a sliding or rotational motion between two parts of a machine. Their main purpose is preventing wear of the points of support of the machine, which would take place if the shafts were to roll directly on the structure.

Are you involved in a project but knowing which bearings you need is giving you headaches? Don’t worry! In this post we will tell you about its uses and types. Let’s get to it!

Which motors are the best for high speeds: step motors or servo motors?

Which motors are the best for high speeds

 

When undertaking a small electromechanical project, one of the most paramount aspects is the selection of the type of motor. With this in mind, we will have to carefully define the requirements of our application in regard to speed or rpm, starting torque, power, torque, etc. In this article we will address the use of step motors and servos in projects that require high speeds. Do you know which one is more appropriate for this requirement? Keep reading.

Types of encoders and their applications in relation to motors

Types of encoders and their application in relation to motors

Encoders are components that are added to a direct current motor in order to convert the mechanical motion into digital pulses that can be interpreted by the integrated control electronics. The main purpose of the various types of encoders  is to transform information from one format to another for standardisation, speed adjustment or safety control.

Gear calculation: essential ideas in your mechanical transmissions

gear calculation

Gears are a key component in a wide range of motion control devices, as well as in mechanical and electromechanical transmissions. In this article we discuss the key elements that will help you with the design of gears for your projects. More specifically, we will focus on their terminology, gear formulas, and even aspects related to gear design that will help you prevent premature failures and perform an optimal gear calculation. Let’s begin!

DC motors and AC motors: selection and application analysis

After telling you about the differences between bushed and brushless motors, we address in detail one of the aspects that limit the most the design of a small actuation solution: the selection of direct current motors (DC motors) and alternating current motors (AC motors). Depending on our drive requirements (speed/rpm, starting torque, power, torque/Lb-Ft, etc.) and the characteristics of each of these motors, we will opt for one or the other. We hope you find our advice useful.

Rolling bearing calculation: analysis of the static and dynamic loads

Roller bearing calculation

The purpose of rolling bearings is straightforward: to bear radial, axial or combined loads in order to improve the operation of mechanical transmission systems. When it comes to speed reducers, rolling bearings counter these static and dynamic loads, guaranteeing the system’s stability and reliability, and the product’s durability. You may be wondering, what are these loads and how do we calculate them? Which steps should we follow to make a proper rolling bearing calculation?
