HAW12 – HAW29 — induction motors for drilling rigs 600–2000 hp, 575 V
Country: France · Model: HAW12 – HAW29
HAW12 – HAW29 induction motors for 600–2000 hp at 575 V for drilling rigs powered from a 40 Hz frequency converter. They drive the top drive, rotary table, drawworks and mud pump. Intra-slot cooling gives more power and torque in the frame of a standard motor.

Description
The patented intra-slot cooling keeps the motor cooler, so the HAW12 gives up to 50 % more power and torque than comparable machines, and the HAW13 up to 33 %, that is, 800 hp in the frame of a 600 hp motor. This way an existing rig is upgraded without changing equipment. The HAW12 has 575 V, 540 A, 1172/2340 rpm and 2690 lb-ft. The HAW13 has 592 V, 686 A, 1181/2400 rpm and 3560 lb-ft. The 1150 hp HAW20 gives 1120 A, 795/2300 rpm and 7610 lb-ft, the HAW22 of the same power 795/3000 rpm and 7680 lb-ft, and the 2000 hp HAW29 1590 A, 795/3000 rpm and 9500 lb-ft. The stator has form-wound windings for 6 poles (4 in the HAW13), class H insulation, Mica-Kapton tape and full vacuum pressure impregnation. Shafts are of 4140/4340 steels, with six 100 Ω platinum RTDs (two per phase), a space heater, IP23 or IP44, and IC06 cooling.
How to choose
The model is selected by power and purpose. The HAW12 and HAW20 are installed in the top drive, the HAW22 and HAW29 on a drawworks or pump, and the HAW13 gives 800 hp in the frame of a 600 hp motor. Options include an encoder, bearing temperature sensors, a blower unit, an air pressure switch, an IP56 terminal box, an insulated bearing and a double shaft end.
