Right angle gear motors & parallel shaft gear motors: performance comparison

The position of the motor’s shaft in relation to the output shaft of the speed reducer is one of the factors that influence the performance and behaviour of gear motors. In this regard, we can find two main variants: right angle gear motors a.k.a. worm gear motors and parallel shaft gear motors. If we take a look at their properties, efficiency, sound level or durability, we will notice significant differences that make them more or less suitable for each application. Want to know why?

Actuators in injection systems: improving fuel efficiency and emissions

In their race for differentiation and competitiveness, automotive brands have put their focus on two mechanical aspects: efficiency and emission control. Most of their R&D is targeted at reducing consumption and offering more Environmentally-friendly vehicles. In this matter, the emergence of electronic control systems has brought a revolution on every level, and both Tier 1 and Tier 2 manufacturers compete with each other to offer end users the most innovative electronic fuel injection systems. In this article, we go over the way in which these devices work and the role actuators play in new electronic fuel injection systems

Problems when using oversized or undersized geared motors

Using oversized or undersized geared motors affects the speed reducer’s service life, its efficiency and the proper functioning of its application. When choosing a speed reducer for a specific movement, we must keep well in mind all the operational parameters or needs of the application. Only then can we choose the proper power for our speed reducer and select the one whose specifications offer the best relationship between efficiency, durability and precision.

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.

What is the service factor and how do you calculate it?

Determining the right load for a motor is paramount, since it improves its optimal performance and allows us to better define its service life. One of the common problems with electric motors is that their performance decreases with loads lower than 50%. Despite overrating being the most common problem, underrating in a motor may be equally or even more damaging. Do you know exactly what is the service factor? This specification tries to measure the external aspects that affect a motor’s performance and cause malfunctions in the gear motor.
