Marine Engineering Series: Marine Control Practice deals with the instrumentation and its associated control systems that are found onboard ships. The book covers topics such as the measuring instruments and control signals for different parameters; system analysis; process and kinetic control systems; and commercially available equipment. Also covered in the book are correcting units such as actuators and valves; the control systems for boilers, turbines, auxiliary equipment; and control involving computers. The text is recommended for those who need to complete the Certificates of Competency for Marine Engineers, including Extra First Class. The book will also be beneficial to offshore engineers.When d.c. motors are used they may be arranged for series, shunt or compound operation. Usually ... Direction of rotation and therefore torque is dependent upon the relative directions of the field flux and the armature current. Direction reversal can therefore be achieved by reversing the current through the field winding or the armature. ... Single-phase induction motors can be used, such as the split- phase motor or the capacitor start motor (where an auxiliary winding is supplied via aanbsp;...
