Technical advances made by Maxon Motor while customising a brushless motor for operation in deep oil boreholes are to be rolled out in a new heavy-duty motor range that has been designed for the harshest conditions on Earth, the company claims.

Maxon responded to the challenge of creating a small motor that was reliable enough to operate at depths of 5,000m by building the EC22 Heavy Duty.

This system features refinements to its rotor, winding, magnets and bearings; enabling it to survive temperatures as high as 240°C and operate at 200°C and atmospheric pressures from high vacuum to 1,700 bar (25,000psi).

In response to requests from engineers, Maxon has vowed to incorporate the same modifications into 16, 32 and 42mm versions of the HD motor, covering a broader range of applications.
