Coreless motors

A wide range of high-quality, and cost-effective, sub-Ø20 mm coreless DC motors, with optional gearboxes and encoders.

We offer a comprehensive range of DC coreless motors with precious metal brushes, matching gearboxes, and encoders. Our motors feature high density windings, neodymium alloy magnets, CNC or stamped enclosures, and preloaded ball bearings. We design matching driver and controller solutions to your application requirements, and offer simulated application validation and lifetime testing services.

Sample request

We aim to get you up and prototyping as quickly as possible. We stock off-the-shelf samples for each motor size, to support commercial development.

Our application engineers can advise on motor design and selection, mechanism design, and support the development of high performance motor drivers. They can also assist to validate the in-application performance and longevity suitability of a down-selected motor or mechanism design.

Contact our application engineering team to discuss your project, using the form, or email [email protected].

We design and manufacture DC Coreless motors:

  • Frame diameters from Ø4mm to Ø20mm,
  • Coreless high density windings,
  • Winding voltages from 2.4v to 18v, with a variety of windings available off-the-shelf for sampling,
  • A range matching planetary gearboxes with ratios from 1:4 to 1:3372,
  • A range of matching encoders providing ABN, and UWV outputs,
  • Precious metal brushes.

We also design and manufacture quick turnaround mechanisms using coreless motors:

  • Slider tables,
  • Ball screw and belt drive positioners,
  • Levers, cams and other slider arrangements,
  • Complex mechanisms: Fully bespoke ground-up designs for complex applications,
