In pumping applications that require a 300HP and above we realize the motor should be built with a larger and more robust frame with features that allow the motor to have superior cooling and pumping power. BMR USA has designed our 300HP-1000HP motors in a large 5800 series frame called the HTA ATLAS SERIES. The HTA ATLAS SERIES has unmatched features to ensure long lasting performance in rigorous applications.
HORSEPOWER RANGES: 300HP-1000HP
SPEEDS: 1800,1200, 900, 720, 600, 514
DESIGN VOLTAGES: THREE PHASE 460, 2300, 4160 AT 60HZ
ENCLOSURES: WPI, TEFC
EFFICIENCY LEVELS: HIGH AND PREMIUM
SHAFT TYPES: HOLLOW AND SOLID
PREMIUM PRODUCT FEATURES AS STANDARD
CERAMIC COATED THRUST BEARING MOUNT
Insulates electric current to prevent fluting in thrust bearings
DOUBLE STACK ANGULAR CONTACT BEARINGS
BMR USA double stacks large 7236B 40 degree angular contact bearings to allow the motor to run on a 175% EHT applications
AIR DUCTED ROTOR AND STATOR DESIGN
In larger frame motors higher heat will be generated, this requires larger air generation and more cooling surface. BMR has designed our larger framed motors to have AIR DUCTED ROTOR AND STATORS to draw air into the hollow rotor core that is air ducted to increase surface space
GUIDE BEARING PROTECTION RINGS
Lower brush grounding rings are installed to conduct shaft currents to the motors ground and doesn’t allow the electrical current from entering the lower bearing causing premature bearing failure
