Baldor Electric Company (Fort Smith, AR) is pleased to offer ABB’s new high inertia motors, ideal for driving large axial fans. 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, says the company. 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.
