Characteristic
Intelligent integration
Built-in Hall sensor, accurately responding to the speed and position control requirements of downhole tool.
CAN bus or RS485 communication interface can be customized to seamlessly integrate with downhole IoT systems, enabling remote monitoring and fault diagnosis.
Efficient and energy-saving
The brushless design efficiency reaches over 85%, reducing the energy consumption of underground equipment.
Long life maintenance free
Brushless wear reduces maintenance costs and safety risks associated with frequent motor replacement underground.
High power density, micro, meeting the installation needs of small downhole spaces.
High-temp. resistance and strong heat dissipation performance
Adopting high temperature resistant windings (H-class insulation) and ceramic bearings, supporting wide temperature operation from -40 ℃ to +200 ℃, combined with efficient heat dissipation shell design, to avoid performance degradation caused by underground high temperature conditions
Application
Micro DC brushless motor, resistant to impact and vibration, strengthened mechanical structure, passed military grade vibration and impact testing, suitable for underground drilling.
Normally it is used in intelligent downhole tools for petroleum, micro electronic hydraulic power systems. The precise control and high stability of HELI motor can achieve 0.1% rotational speed accuracy, so also suitable for precision scenarios such as logging instruments.
