Brushless Motor resists extreme operating conditions.
January 13, 2011 -
Measuring 22 mm in diameter, heavy-duty Model EC22 HD is intended for deep drilling applications at depths of 16,000 ft and in boreholes up to 36,000 ft long. Motor operates at temperatures up to 240°C and under atmospheric pressure conditions from high vacuum to 25,000 psi, while resisting impulse and impact forces of 100 G. With efficiency above 70%, motor can operate while submerged in oil, trebling 80 W output rating to 240 W. Efficiency in air is 88%.

Heavy Duty Drive Solution for Extremely Harsh Operating Conditions
maxon motor launches its EC22 HD (Heavy Duty) motor, a 22mm-diameter brushless motor that outperforms any other commercial electric drive on shock, vibration and temperature tolerances. This motor was developed for the exceptionally high requirements in deep drilling technology and resists the most extreme operating conditions.
The electronically commutated EC22 HD (heavy duty) motor was developed in collaboration with the oil exploration industry and is designed to operate at depths of around 16,000 feet and in boreholes up to 36,000 feet long.
As part of the motor's development program, a high-temperature test facility was built, and extensive field trials were undertaken. The motor operated at temperatures up to 240°C and under atmospheric pressure conditions from high vacuum to 25,000 psi. 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 because of the improved heat dissipation.
Although developed to perform critical downhole actuation functions, maxon believes the new motor will also appeal to other industries where reliability is essential. The motor's efficiency of 88% in air (and above 70% in oil) makes it particularly suitable for battery-powered applications
