Baldor's RPM PD platform produces full power over extended speed ranges.
Baldor Electric Company introduced a new platform of DC motors in a low profile and power dense design. The RPM PD series offers an alternative to motor rewinds or AC conversions. The RPM PD series offers an optimized armature design to produce full power, over extended speed ranges with smooth torque transitions and minimal cogging, while operating at very low speeds. Longer length standard brushes, with a mechanical monitoring system, offer increased run time between scheduled maintenance shutdowns. Standard brushes are placed in a rotatable brush gearing system for a simplified change out process – including a “snap point” alignment pin, allowing the brush gear system to be rotated when removing or adding brushes. The RPM PD series includes 125-1200 Hp, NEMA Base Speed, a variety of enclosures (Drip Proof Force Vent; Totally Enclosed Air/Water Cooled; Totally Enclosed Air/Air Cooled) and shaft grounding brush standard on drive end.
