The MHT 380 190 / 190 N1 30 motor belongs to the Vane Motors series manufactured by Vickers to convert hydraulic energy into controlled rotary motion for automation circuits. It tolerates system pressures up to 138 bar, allowing full-load operation without premature wear, and reaches 200 rpm at that pressure for low-speed drives that still require consistent speed. Port A provides clockwise rotation so designers can match shaft direction to the load. A theoretical displacement of 2 358.5 cm³/rev in 190 mode moves significant fluid volume per turn, while 4 716.9 cm³/rev in 380 mode doubles that output for higher flow demands. The unit delivers 258 Nm of torque for every 100 psi in 190 mode, supplying moderate force where precise positioning is needed. A minimum case flow of 1.89 l/min removes heat and lubricates internal bearings, and a 1/8 NPT grease fitting port lets maintenance crews re-pack bearings without disassembly.
The output shaft uses 48 rotor spline teeth to transfer torque evenly into couplings, and a 104.78 mm shaft seal keeps pressure oil inside the housing while blocking contaminants. A spline base diameter of 105.58 mm defines the root dimension for mating hubs, and a diametral pitch of 10/20 sets tooth size so standard components fit without modification. The 121.92 mm pitch diameter positions the load path at the correct radius for efficient torque transfer, while a 30° pressure angle balances strength with smooth engagement. In 380 mode the motor produces 515 Nm of torque for every 100 psi, offering high output for heavy equipment that demands substantial starting and running force.
