Bardzo proszę o pomoc w przetłumaczeniu słowa "thruster".

"Shoe Brakes are supplied ready for installation, with Thruster full of oil and with main spring pos. 14 set to the minimum value of Braking Torque."

"The Thruster’s motor must be connected to the machine’s main motor."

"The instructions for the electrical connection can be found inside the terminal box cover; the Thruster can be star or delta connected as shown in the following drawing."

"It is not suggested to make a series connection with the machine’s main motor because, especially with high power motors, it is possible that the remanent magnetism and the persistent movement of the machine’ motor’s rotor can cause residual current which can exert an influence on the Thruster’s motor increasing its closing time."

Z góry serdecznie dziękuję.
