Permanent magnet DC (PMDC)

Kollmorgen’s permanent magnet DC motors offer rugged, quality construction and dependable operation. This design uses permanent magnets in place of a wound field to enable a lighter, more compact and efficient motor with a wider speed range and an exceptionally linear speed/torque curve. Many options are available, including explosion-proof and washdown models, as well as cost-effective co-engineered modifications.
