HAW12/HAW13/HAW20/HAW22/HAW29 — drilling induction motors 600–2000 hp, 575 V, for variable-frequency drive
Country: USA · Model: HAW12 / HAW13 / HAW20 / HAW22 / HAW29
HAW series drilling motors are AC induction machines of 600–2000 hp at 575 V for variable-frequency drives of drilling rigs. They equip the top drive, rotary table, drawworks and mud pumps, and such motors already work on over 600 drilling rigs.

Description
Patented in-slot cooling, an optimised copper-to-steel ratio and improved slot and bar geometry give more power and torque within the frame size and weight of standard lower-power motors. Thus the HAW12 delivers up to 50 % more power and torque than comparable machines of the same frame size. This makes it possible to drill deeper and faster, extend horizontal sections and raise pump pressure. Rated voltage is 575 V ±10 % (592 V for the HAW13), rated frequency 40 Hz. The form-wound windings have class H insulation, turn insulation with mica-Kapton tape and robotic winding, and full vacuum impregnation. Shafts are made of 4140 and 4340 steels, the frame of ductile iron, and the winding contains 100 Ohm platinum resistance thermometers, two per phase. The enclosure is IP23, for the HAW22 and HAW29 IP44, the terminal box is IP44, cooling IC06.
How to choose
The top drive and rotary table are equipped with the HAW12 (540 A, 2690 lb-ft at 1172 rpm, up to 2340 rpm). The HAW13 (686 A, 3560 lb-ft at 1181 rpm, up to 2400 rpm) fits 800 hp into the standard 600 hp frame size, and the vertical HAW20 at 1150 hp (1120 A, 7610 lb-ft at 795 rpm, up to 2300 rpm) is made for the top drive. The horizontal HAW22 at 1150–1350 hp for the drawworks and pumps gives 7680 lb-ft at 795 rpm at 1120 A, maximum 3000 rpm. The most powerful HAW29 at 1500–2000 hp draws 1590 A and develops 9500 lb-ft at 795 rpm. Ambient temperature is from −40 to +40…+55 °C depending on the model.

FAQ
What options can be ordered for the HAW drilling motor?
To order, an encoder, bearing temperature sensors, a fan unit, an air pressure switch, an IP56 terminal box, an insulated bearing and a double-ended shaft are fitted. ATEX, IECEx, CSA, ABS and DNV certificates are provided on request.
Where are the HAW motors made and serviced?
The motors are made and serviced in Houma (Louisiana) and Houston (Texas), and the field service team works 24/7.
How are the HAW drilling motors tested before shipment?
Each motor undergoes a dielectric strength test of the insulation. A heater and glass-fibre sleeves on the bolted connections are part of the standard version.
Can the HAW be installed on a rig in service?
Yes, higher power within the same frame size and weight makes it possible to upgrade the rig without changing the equipment structure and to reduce transport costs.
