Maxon Motor’s (www.maxonmotor.com) has launched the EC 22 HD (Heavy Duty), which is a standard motor suitable for use in harsh ambient conditions. Specifically designed to meet the deep drilling technology’s exceptionally high requirements, the electronically commutated motor EC 22 HD can withstand even the most extreme operating conditions.
Offered in different variants, the new EC 22 HD are developed for operation in use in air or submerged in oil. Its assigned power rating relies on the surrounding medium and averages 240 Watts in oil and 80 Watts in air. Designed to cope with ambient temperature of over 200°C (390°F), the servo motor can also withstand atmospheric pressures of up to 1’700 bar (25’000 psi).
Its 22 mm diameter motors can withstand impact and impulse of up to 100 G and vibration of up to 25 grms. Featuring high efficiency — that is up to 88 percent in air and more than 70 percent in oil — the motors provide the best prerequisite for battery-based applications. The motor possess excellent regulation behavior as it offers a detent-free running characteristics, making it ideally suited for high-precision positioning tasks, even at low speeds.
The new EC 22 HD unveils new possibilities in various applications that demand for equally high requirements. Thus, the motor is not only well-prepared for use in space technology, but in power plants, aircraft industry, vehicle manufacturing and in mining as well.
