Internal rotor motors

internal brushless dc motors - up to 14000 rpm, 942 watt

From highly economical to extremely powerful, Nanotec's internal rotor motors are available in numerous variants and can be combined with a controller / drive, gearbox, and encoder to create a tailor-made solution.

  • Sizes from 22 to 87 mm
  • Rated speed 3,000 – 14,000 rpm
  • Rated power 4 – 492 W

In internal rotor BLDC motors, the rotor with the permanent magnets rotates on a shaft inside a stationary stator with coils. Their benefits lie in their lower rotor inertia and their better dissipation of heat losses. They are particularly suitable for high speeds.
