The new, electronically commutated EC-4pole 32 HD with planetary gearhead motor by maxon precision motors has all the features of its predecessor, the Heavy Duty Motor EC 22 HD, but with a larger and more powerful size. It is designed for extremely rough operating conditions, particularly applications in deep drilling.
深入的钻井技术使得可以从超过2500 m的深处回收石油和天然气。通过将深入钻孔与方向钻孔或孔在地球中的动态定位相结合，以前无法实现的油储备打开，钻孔深度约为5000 m，钻孔长度高达11,000 m。这些深度的温度和压力，加上钻井工作期间发生的强振动，对使用电子驱动器提出了独特的挑战。
EC-4Pole 32 HD的不同版本设计用于在空气中运行或在液压油中泛滥。功率额定值取决于周围的介质，空气中的220 w，由于热流量高得多，油中的机油为480 W。它们的设计用于超过200°C的环境温度和高达1,700 bar的大气压力。直径32毫米的电动机还必须能够承受高达GRMS = 25的振动以及最高1000 G的影响。例如，一级方程式1车辆暴露于大约2 g，战斗机暴露于大约13G.电动机具有高效率 - 到89％的空气，超过80％的机油 - 非常适合用于电池操作的应用。凭借其无置态运行属性，它们具有出色的控制特性，并且适用于外太空的高精度定位任务，即使在低速下也是如此。
The EC-4pole 32 HD is ideal for use in environments with extreme temperatures, subject to high vibration, or under ultra-high vacuum. This means the motors can also be used in aerospace applications, for instance in gas turbine starters, for the generators of jet engines, for regulating combustion engines, or for exploration robots. For the use of the motor in conjunction with a gearhead, maxon offers the GP 32 HD, a powerful and robust planetary gearhead.
