New ABB High Inertia Motors Now Available from Baldor
Large axial fans are high inertia loads, which mean that motor start times are increased. With a standard motor this could lead to overheating, but the ABB high inertia motor is specially designed to withstand the increased temperature rise during start and stall conditions, and have stall times longer than their start times.
Based on ABB's well-established reliable modular induction motor, the new high inertia motors utilize optimized rotor bar designs made from carefully selected materials, including higher resistivity copper alloys. The motors have been re-dimensioned to accommodate the temperature rise associated with high inertia starts, and the overall design has been optimized to achieve balance between torque and temperature performance.
The 6 – 10 pole motors are designed in accordance with NEMA standards. They cover the power range 7000 to 18500 HP in frame sizes 710-900. Voltages can be supplied up to 13.2kV 60 Hz, with cooling systems available as WPII, TWEAC and TEAAC.
