DC CONTROL-SPEED MOTORS
APPLICATION
The DC control-speed motors for drives type Pg112 are destined to supply via frequency converters and are fitted with equipment where speed regulation is required (lathes, sugar diffusers).
Motors type Pg112 is mostly destined for main propulsions of lathes with digital management. It is also found in various type of industry propulsions where double-zone motor speed control with wide range is required.
TECHNICAL CHARACTERISTIC
Motors have extorted cooling by over built blower that is driven by three phase motors and are applied with tacho-alternator that is mounted at the other end of shaft. The motor type Pg112 is four polar machine, other-excite with polar commutation and compensation wire. The stator tetrahedron frame less is whole plated. It is possible to make motors with the other technical parameters and additional equipment (resolver, air filter, temperature sensor, antiradioelectric filter).
Protection degree IP22.
