DC MOTOR

Permanent Magnet DC Motors

Our customized motors in sizes 63 and 71 are equipped with permanent magnet excitation with flux concentrators, designed to withstand high demagnetizing currents. This innovative feature allows for versatile use over a wide range of speeds, both in constant and variable torque regimes, even when driven by speed drives with a low form factor. Under these conditions, the motors ensure high efficiency and low-noise torque ripple, offering exceptional performance.

Features

  • 2-pole Magnetic Circuit with Flux Concentrators, Ferrite Magnets
  • Cooling IC410
  • Bearings with Increased Clearance, Shielded and Lifetime Lubricated
  • Construction Form IMB5, IMV1, and IMV3 for Motors in Sizes 63 and 71
