EC22 Heavy Duty (HD) motor – technical briefing - .PDF file.

Maxon Motor has launched the EC22 Heavy Duty (HD) motor, a 22mm-diameter brushless motor with high shock, vibration and temperature tolerances suitable for the extreme conditions of deep drilling.

The motor’s efficiency of 88 per cent in air (and above 70 per cent in oil) makes it particularly suitable for battery-powered applications.

The electronically commutated EC22 HD brushless servo motor was developed in collaboration with the oil exploration industry and is designed to operate at depths of around 16,000ft and in boreholes up to 36,000ft long.

As part of the motor’s development program a high-temperature test facility was built and extensive field trials undertaken.

The motor operated at temperatures up to 240C and under atmospheric pressure conditions from high vacuum to 25,000psi.

It has also been proven to resist impulse and impact forces of 100G.

It can operate while submerged in oil, trebling its 80W output rating to 240W due to the improved heat dissipation.

Although developed to perform critical downhole actuation functions, Maxon believes the motor will appeal to other industries where reliability is essential.

maxon motor is the world’s leading supplier of high-precision drive systems.

maxon has earned a reputation for constant innovation and unflinching reliability – seeing the company’s products used by the world’s top engineers in fields as demanding as space exploration, formula 1 racing and sub-sea applications.
