E.GO: needle winding technology for brushless electric motors


E.GO has invested time and resources in winding technologies for brushless motors and has reached high competency levels. “We may be the ideal partner for motor companies that are moving towards a new generation of BLDC stators, thanks to our numerous winding methods – the company explains –. The degree of system automation is defined based on customer production requirements, in order to create fully customized systems. The winding unit is the main unit, around which all other operating units are developed, for preparation, finishing, test and assembly work”. Using needle winding technology, E.GO can provide the following functions during the product production: winding of brushless stators with programmable wire stratification by means of needle winding technology for high slot fill and accurate coil wire positioning; high speed needle winding with multiple stations to reach maximum productivity; fully programmable wire termination system using robotics to carry out complex coil interpolations and wire-lead cuts in short time and limited space; high speed, precision insulator paper formation and placement; and quick tooling change system to optimize and speed up production changeover times. Besides, E.GO machines are equipped with a monitoring software that instantaneously supplies a vast amount of information, useful for performance analysis and diagnostics, such as production data, yields and alarms. The software allows storing the data and the alarm log history and provides traceability for each single piece.
