All DC Motors

Brush DC Motors are small but with high power density to provide the advantages of low friction, low starting voltages, minimal iron losses and superb speed-to-torque performance

SMALL DC MOTOR

A brushed DC motor from Portescap is ideal for portable and small devices. Brush DC motor technology offers the distinct advantages of low friction, low starting voltages, absence of iron losses, high efficiency, good thermal dissipation and linear torque-speed function. These ultra-compact small DC motors are designed to deliver superb speed-to-torque performance with lower joule heating. We also offer a variety of gearheads and encoders. Portescap small DC motors can deliver a torque range from 0.36 mNm up to 160 mNm continuously and from 2.5 mNm up to 1,487 mNm in intermittent operation. In addition, Portescap proudly offers our special line of high power density DC motors, the Athlonix series! Our brushed DC motors are designed for quick and easy modification, so you can get exactly what you need with the pricing and delivery you expect from an off-the shelf solution. We can customize standard brush motor features to meet specific application requests, including performance specifications, mounting configuration, thermal and ambient condition requirements, and other operational needs.

Portescap's small brush DC motors are ideal for your portable and small devices. Our continuous innovation in coreless motor technology enables us to offer:

  • Frame sizes from 8 to 35 mm
  • Speeds from 5,000 to 14,000 rpm
  • Continuous motor torque - 0.36 to 160 mNm
