Electric motors
... To better manage and protect them!!
Electric motors are nowadays, with the exception of deviceslighting, most receptors in many industries andtertiary facilities. Their function, to convert electrical energy intomechanical energy, give them any economic importanceso no special installation designer or maker,no installer and no operator can ignore them.
Among all the types of existing motors, asynchronous motors including phase squirrel cage motors are the most used inindustry and beyond a certain power in applications of commercial building. Furthermore, although their order by equipmentcontactors is perfectly suited for manyapplications, the use of electronic equipment in constantprogress broadens their scope. This is the case for the controlstarting and stopping with soft starters, speed
bumps, aswhere precise speed control is necessary withspeed-regulating drives .However, induction motors rings are used for somehigh power applications in industry and asynchronous motorsSingle phase are suitable for applications with limited powersrather for building applications.
The use of so-called synchronous brushless motors or magnets Permanent associated converters is spreading inapplications requiring high performance, including torque Dynamic (at startup or diet changes) andaccuracy and speed range.
This Technical Specification, after a presentation of the various types of engines electrical and their operating principle, details more particularly the technical and job characteristics of enginesAsynchronous, including key starters, the speed control and braking associated therewith. It is a basic basic knowledge to understand all the problems that
represents the control and protection of motors.
This Cahier Technique briefly discusses the change in speed electric motors. This is discussed specifically in Notebook Technique CT 208 "electronic speed controllers and starters". Motor protection is the subject of a Cahier Technique being writing.
