Acoustic analysis of electric motors in noisy industrial environment

This paper presents a method for the acoustic analysis of electric motors in noisy industrial environments. Acoustic signals were measured via acoustic camera 48-microphone array, which has the capability to localize a sound…

Materials and efficiency in comparison

The attainment of the best efficiency of an electric motor involves several aspects. Among them, also the choice of the materials constituting the core, from the magnetic lamination to the stator pack. Today…

HIGH EFFICIENCY MOTORS

Permanent magnet synchronous motors and synchronous reluctance motors

by Sandro Calligaro, Free University of Bozen – High efficiency electric motors: permanent magnet synchronous motors and synchronous reluctance motors. According to some studies, electric motors are responsible for about 45% of the…

You learn by making mistakes in a hydraulic power plant

Problem solved in a hydraulic plant that did not respond to controls after some hours of operation. Nothing is truer than this saying, especially in the mechanical engineering field. The engineering progress is…

The importance of the shaft alignment

In the following article, we are treating the fundamental aspects to be known for the error-free alignment of two shafts. Aligning two shafts means to make them share the same rotation axis, precisely…

Human-Robot Collaboration: Hand-in-Hand Gripper

Human/robot collaboration requires intelligent and safe grippers. In technology studies, Schunk shows what is important for HRC-capable actuators, which minimum standards must be fulfilled and what is already possible today. And what is…

A novel mechanism for gearing using purely rolling balls

Bearings for Gearing

Pál Bogár, Sincroll Drive Technologies – A novel mechanism for gearing is presented that uses balls to intermediate between the input and output wheels. The balls carry out pure rolling without sliding while…

Much higher performances than with conventional air supports

Active air bearings controlled by piezoelectric actuators

Federico Colombo, Luigi Lentini, Terenziano Raparelli, Vladimir Viktorov, Politecnico di Torino –  The article illustrates some of the most recent typologies of active air bearings, controlled by piezoelectric actuators. This active control methodology is…
