Electric motor components

stator segment with overmolded plastic insulation

  • Length: currently up to 200 mm is possible

Application:

Industrial engines, hybrid automobile technology, wheel hub drives

Advantages:

  • High coil density
  • Compensation of stack tolerances from 0.8 mm before the insulation to 0.05 mm after insulation
  • Ensuring the air gaps and creepage distances in the joint area of the individual segments

stator segment: overmolded - wound - encapsulated

  • stack height = installation height: 105 mm
  • stator composed of 30 segments / Ø 290 mm

Application:

Hybrid drive passenger car (Plug-In), power: 80 kW

Advantages:

  • Stack, overmolding, winding and encapsulation from one supplier
  • High coil packing density with small dimensions
  • Contour for placing the winding wire is integrated in the part
  • Sealing of the winding wire without damage of isolation
  • Additional fixing of the winding by encapsulation

Skewed external rotor stator with overmolded plastic insulation

  • Diameter: 150 mm
  • Installation height: up to 85 mm
  • helix angle: 6°

Application:

Powerful industrial engines

Advantages:

  • Reduction of the detent torque
  • Use of loose laminations
  • Stacks need no welding
  • Reduction of noise
  • Insulation displacement contacting integrated in the geometry

Skewed internal rotor stator with overmolded plastic insulation

  • Diameter: 66 mm
  • Installation height: 52 mm
  • helix angle: 6°

Application:

Electric steering in cars

Advantages:

  • Reduction of the detent torque
  • Use of loose laminations
  • Stacks need no welding
  • Substitution of the powder coating

Overmolded stator and rotor

  • Diameter of stator: 120 mm
  • Diameter of rotor: 84 mm
  • Installation height: 14.5 mm

Application:

Fan for engine cooling consisting of overmolded stator and overmolded rotor with magnetized and preassembled magnets

Advantages:

  • Weight and space savings
  • High temperature applications
  • Subsequent magnetization not necessary

Encapsulated rotor with rare earth magnets

  • Diameter: 90 mm
  • Installation height: 20 mm

Application:

Drive for engine cooling in cars

Advantages:

  • Complete overmolding prevents corrosion of the magnets
  • Magnets are fixed in their position by the plastic

Stator with a plastic overmolding before and after the winding

  • Diameter: 35 mm
  • Installation height: 33 mm

Application:

Electric fuel pump for cars

Advantages:

  • Additional protection of the coil against external influences combined with improved heat dissipation
  • Additional fixation of the coil and the contacting

Stator with overmolded ball bearings / sintered bearings

  • Diameter: 45 mm
  • Installation height: 33 mm

Application:

Power tools

Advantages:

  • No additional safety components required
  • Assembly process not necessary

Stator with contact ring and cover cap

Advantages:

  • Perfect coordination of the individual components to ensure an optimal and automated assembly at the customer's location

end cap insulation / end shields

  • Diameter: up to 200 mm

Application:

Use in engines with small quantities and / or large variance in height

Advantages:

  • One and the same end shield can be used for different heights

Disadvantages:

  • Poor heat dissipation from the stator winding
  • End shield and paper is not fixed and can thus change its position
  • It is not possible to balance the lamination tolerance through the plastic
