400 HP Vertical AC Top Drive Motor

The Only Heavy Duty 400 HP Form Wound Motor Designed for Top Drives.

In severe conditions, random wound motor failures are caused by a combination of several destructive factors including high VFD voltage spikes, excessive top drive vibration, rain and contamination (weather conditions), random windings (weaker than form wound) and overheating.

That’s why we designed and built the first heavy duty form wound 400 horsepower top drive motor with a better designed and engineered optional cleaning motor blower.

Gulf Electroquip DRILLMAX motors satisfy a wide range of applications within the oilfield industry.  The GEQ DRILLMAX600 and GEQ DRILLMAX600 XL Top Drive Motor was developed to meet required specifications of the IEC 60034.1 standards.

We listened to drillers and built a 400 HP top drive motor that works better and lasts longer.

Ideal for oil and gas rig top drives.
