Sub­sea thruster, sub­mersible DC mo­tor and ac­tu­a­tor range set to ex­pand

With the “suc­cess­ful” launch of the MT30 sub­sea ROV thruster from maxon mo­tor, the drive spe­cial­ist is ex­pand­ing the range of ROV thruster sizes and sub­mersible mo­tors with pres­sure com­pen­sa­tion ves­sels.

The MT30 sub­sea ROV thruster from maxon mo­tor cre­ated a huge im­pres­sion with 10Kg of bol­lard thrust from a 30mm di­am­e­ter sub­mersible brush­less DC mo­tor. Soon it will be­come just one op­tion in the range of thrusters from the DC mo­tor man­u­fac­tur­ing mar­que. With a nat­u­ral affin­ity suited to harsh ap­pli­ca­tion re­quire­ments the maxon range of heavy duty brush­less mo­tors (HD mo­tors) were de­signed orig­i­nally for use in down hole drilling rigs where ex­tremely high shock, vi­bra­tion and tem­per­a­tures are ex­pe­ri­enced. The brush­less HD mo­tors in each power level have a ver­sion de­signed for sub­mer­sion in oil. It is a nat­u­ral pro­gres­sion for the oil filled mo­tors to be en­cased and pres­sure com­pen­sated for use sub­merged in sea­wa­ter. This can be in the form of a thruster for un­der­wa­ter craft propul­sion, an ac­tu­a­tor for un­der­wa­ter in­stru­men­ta­tion or a com­bined mo­tor, gear­head and sen­sor feed­back assem­bly to­tally sealed and pres­sure com­pen­sated for un­der­wa­ter tools and sub­sea valve con­trol. The thruster sizes will range from 20mm through to 70mm di­am­e­ter and will be avail­able with the op­tion of sub­con con­nec­tors or cus­tom ca­ble (um­bil­i­cal), com­pen­sators and con­trol elec­tron­ics.
