Electrical engines are found in all types of modern applications ranging from industrial fans to computer CD drives. Designing, manufacturing and maintaining electrical engines requires specialised training; the type of training you choose will depend on they kind of motor winding work you plan to do. For instance, the skills required to maintain the electrical motor of a computer's hard drive are not the same as those you need to adjust the motor winding of a hydroelectric turbine. Nearly 50% of motor failures are caused by malfunctions in the rotor and stator windings.
Decide what type of motor winding work you want to practice. Short certificate courses in winding and assembly are available for electrical motor winding technicians, while a full degree or even an advanced degree course may be required to design the winding of an advanced electrical motor.
Take courses, or teach yourself through textbooks, the basics of electric motor design. This will require an understanding of Maxwell's equations, Ampere's law, Faraday's law, Gauss' law for magnetic fields and an understanding of magnetic circuits. For example, you should be familiar with terms such as flux, inductance and reluctance.
Learn the fundamentals of motor mechanics. This includes a working knowledge of the function, assembly and maintenance of shafts, bearings, stator cores, rotors and motor housings.
Study how to identify and use the different types of winding connections, diagrams and formulas involved in motor winding. Learn how to adapt winding diagrams for different types of motors, such as series delta, parallel delta, consequent pole and series star-connected motor windings.
Practice how to use electrical and mechanical test equipment, such as AC dielectric test sets, dial indicators and radio meg-ohmmeters to diagnose and inspect motors.
Take a certification course in motor winding if your local regulatory body requires it. Even if certification is voluntary, it may be a good idea to invest in a certification course as it will increase your chances of finding employment and receiving promotions.
