maxon motor launches with its EC 22 HD (Heavy Duty) a standard motor for extremely harsh operating conditions. Developed for the exceptionally high requirements in deep drilling technology, the electronically commutated motor resists extreme conditions. The different variants of the motor are designed for operation in air or submerged in oil (flooded in hydraulic fluid). Their assigned power rating depends on the surrounding medium and averages to 80 Watts in air and, due to higher heat dissipation, 240 Watts in oil. They are designed to cope with ambient temperatures of more than 200°C (390°F) and atmospheric pressures of up to 1'700 bar (25'000 psi). Further requirements of the 22 mm diameter motors are the capability to withstand vibration of up to 25 grms as well as impulse and impact of up to 100 G.
