14 Terminologies Used for Power of the Ship’s Marine Propulsion Engine

From: https://www.marineinsight.com/main-engine/12-terminologies-used-for-power-of-the-ships-marine-propulsion-engine/ The best thing about being a marine engineer on a ship is controlling the most powerful thing in the world ever created by man- the ship’s main propulsion engine. The Wartsila Sulzer RT-Flex 96 C is the world biggest and most powerful engine ever made with an output of approx 80000 KW or 108900 BHP. The overall operation of the ship is highly dependent on the performance of its main propulsion engine, measured in terms of its power rating. There are several terminologies for “Power” rating used for Marine Propulsion Engine and each of these gives different value of engine performance under various parameters and situations. Representation Image Following is the list of “Power” Terminologies used for a Marine Propulsion Engine on board ship: 1 . Effective Power : The Power available at the output side of the engine i.e. at crankshaft flange of th

Stepper Motor

Basics of Stepper Motors Every motor converts power. Electric motors convert electricity into motion. Stepper motors convert electricity into rotation. Not only does a stepper motor convert electrical power into rotation, but it can be very accurately controlled in terms of how far it will rotate and how fast. Stepper motors are so named because each pulse of electricity turns the motor one step. Stepper motors are controlled by a driver, which sends the pulses into the motor causing it to turn. The number of pulses the motor turns is equal to the number of pulses fed into the driver. The motor will spin at a rate that is equal to the frequency of those same pulses. Stepper motors are very easy to control. Most drivers are looking for 5 volt pulses which just so happen to be the voltage level of most integrated circuits. You merely need to design a circuit to output pulses or use one of ORIENTAL MOTOR's pulse generators. One of the most remarkable features of stepper moto
