Product Description:

RM Series Rig Motor

Product Overview

Rig motors are core power equipment for drilling operations, driving drawworks, mud pumps and rotary tables under high temperature, heavy vibration, dust and corrosive working conditions.

Our RM series rig motors are developed with 30 years oilfield experience, deployed on over 900 drilling sites across 28 countries. All motors pass strict factory testing and meet API 7F, IEEE 841, IEC 60034, NACE MR0175 and DNV GL offshore standards with full component traceability.

Core Advantages

Ceramic composite winding insulation + gradient cooling technology, MTBF 42% higher than industry average
HVOF coated bearings and full anti-corrosion coating, stable operation in H2S sour gas and saltwater offshore environment
AC induction & permanent magnet two structures, PM type saves 15% energy consumption
Reduce maintenance cost up to 60% and downtime by 75%; global warehouses support 24–48h spare parts delivery
Multiple cooling & protection grades, customizable voltage, enclosure and cooling system for various harsh drilling scenes

Failure Solution & Technical Innovation

Ceramic composite insulation (patented): 3 times dust & moisture resistance, stable insulation resistance under long-term harsh environment
Gradient variable-speed cooling system: Auto adjust airflow by winding temperature, cut cooling energy consumption by 22% and lower winding temperature greatly
HVOF reinforced bearing & NACE certified anti-corrosion structure: Avoid bearing seizure and sulfide corrosion in sour wells
Redundant cooling design for offshore PM motors: Prevent overheating failure caused by temperature fluctuation; encapsulated NdFeB magnet to avoid demagnetization under heavy load
