PRECISION DC CORELESS MOTOR

Coreless windings are utilized in our precision DC coreless motors (Micromotors). Due to an 
integrated structure consisting of a symmetrical winding, commutator and motor shaft, these motors 
are very smooth and stable running and without vibration. The motors are characterized by: 

  • low inertia 
  • rapid acceleration 
  • high efficiency 
  • no cogging and linear output performance

They have excellent speed regulation and servo performance. High performance Nd-Fe-B magnets 
are used, and the product is compact in size. The motor with precious metal commutation is used 
in low power applications, whereas carbon-brush commutation is used in higher power applications 
with long operational lifetime. The product is typically used for precision drives in medical equipment 
and devices, healthcare products, robotics, automotive, and industrial automation
