Technology

he installation technology comprises the assembly of rotor and stator as individual semi-finished products and their final assembly in the motor. For this process, manual devices or completely automated lines with a capacity of 2,800 motors per shift are used according to the quality requirements and productivity. 

The following technologies are used for the assembly: 

  • Stamping by controlling the force and path: shaft, commutator, balancing rings, bearings, terminals, flanges, casings, etc.  
  • Inserting the groove insulation and installation of front insulation if the stack is not pre-insulated with injection moulding 
  • Installation (stamping, affixing, potting) of magnets for EC application 
  • Winding: 
    • Flyer technology  
    • Needle winding 
    • Pole-chain winding 
    • Prototype winding of samples 
    • Wire manipulation to contact position    
  • Contacting: 
    • Terminal impressing/piercing the wire 
    • Crimping of terminals to wire 
    • Resistance welding of terminal and wire 
    • Laser welding of terminal and wire (in development) 
  • Balancing: 
    • Milling of balancing rings or blades 
    • Cutting of sheet metal 
    • Adding balancing putty 
    • Drilling holes in balancing ring
  • Impregnation: 
    • Varnish trickling 
    • Potting in vacuum 
  • Bonding: 
    • Surface conditioning with laser, plasma, washing and sanding 
    • Orbital and standard riveting 
    • Laser welding of plastic materials 
    • Gluing with various materials 
    • Ultrasonic bonding 
    • Tight fit (also heating or cooling of components) 
    • Screwing with torque and turn control 
  • Controls: 
    • Optical control, machine vision, 3D scanning 
    • Thermal vision control of contact 
    • Acoustic measurements 
    • Electrical measurements 
    • Vibration measurements 
    • Tightness measurements 
  • Traceability:  
    • Labelling or laser engraving 
    • Material traceability per piece 
    • Traceability of process parameters per piece 
    • Traceability of all controls per piece
