Smaller and lighter ABS oil pump motors.


In the automotive sector, the trend towards smaller and lighter motors involves a constant balance between lower fuel consumption and consumer demand for more options. Aisin Seiki in Japan, produces a highly compact design. The Somaloy®- based motor offers comparable performance, but is 36% shorter and weighs 17% less. Somaloy® technology with its intrinsic freedom to apply 3D design, has been utilized in the following ways to create a more compact motor:

• The copper wire can be wound more efficiently, reducing the length required.
  
  
• By eliminating sharp edges, the copper winding can be made tighter.
  
  
• The commutator, which controls power to the copper winding, has been integrated into the design. 
  
  

Modular assembly

The motor has individual pre-wound teeth with a built-in mounting feature for assembly. This design utilizes some important Somaloy® features.The 3D flux capability and rounded, smooth finish ensure windings with a high packing factor and good thermal conductivity.

This free piston cooler is produced by the Twinbird
Corporation of Japan. The linear motor drive contains
two Somaloy® stator parts. As a result, the
assembly is easier and cheaper to manufacture compared
to the laminated predecessor.

The right material in the right place

The axial flow motor combines both Somaloy® and laminated steel in one and the same motor. The Somaloy® teeth provide a smooth rounded finish for winding with a high packing factor.
The compacting technology for 3D flux
and built-in skew is utilized. The laminated
steel stack carries the 2D flux in the back
iron and also acts as an assembly feature for the teeth.
