What is continuous maximum rating motor?

What is continuous maximum rating motor?

The rating of the motor selected for this duty is called its continuous rating or design rating. By Continuous Duty Motor rating one means that it is the maximum load that the motor can give continuously over a period of time, without exceeding the temperature rise.

What is the maximum rating of an engine?

Maximum continuous rating (MCR) is defined as the maximum output (MW) that an electric power generating station is capable of producing continuously under normal conditions over a year. Under ideal conditions, the actual output could be higher than the MCR.

What is MCR and NCR of engine?

MCR Maximum Continous Revolution of Main Engine. NCR Normal Continous Revolution.

What is NCR of an engine?

Within ships, the nominal continuous rating (NCR) of 90 percent of the maximum continuous rate (MCR) is standard. Usually, 90% of a propeller’s output is considered its technical output. A normal ship’s normal output is 75% to 77% of MCR on average.

What is continuous rating?

Definition: The constant voltage or current that a device is capable of sustaining. This is a design parameter of the device.

What is a continuous rating scale?

a scale on which ratings are assigned along a continuum (e.g., a line) rather than according to categories. Such ratings are made by making a mark on the scale to indicate the exact “placement” of the rating or by assigning a precise numerical value. Also called continuous scale.

What is max continuous power?

Maximum continuous power (MCP) is the maximum power the engine/drive system should be exposed to for long periods of time. This power level may be exceeded for shorter time periods.

What is maximum continuous thrust?

A: Maximum continuous thrust is the most thrust an engine can produce over a long period of time. An engine can produce more thrust than the maximum continuous level, but only for a few minutes. (This is called maximum takeoff thrust, and is physically the most thrust an engine can produce.)

What is an engine rating?

Engine rating means a unique combination of displacement, rated power, calibration (fuel, emission, and engine control), AECDs, and other engine and emission control components within an engine family.

What is maximum continuous rating of boiler?

Maximum continuous rating (MCR) is the capability of steam boiler to produce and provide the stated quantity of steam continually and easily with no all kinds of deficit or unwanted effects (for example overloading, slagging, or overheating) upon the principal steam boiler and its components.

What is ECR and MCR of boiler?

As per Boiler Burner concern ECR is electronic compound regulation and MCR is mechanical compound regulation…in ECR, burner air and fuel is controlled by electronically and in MCR by mechanical linkage.

What is Torque rich?

Torque rich-A phenomenon that causes a slowdown in main engine speed and engine overload, due to factors such as hull fouling and engine contamination or damage.

What is bore ratio?

In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length.

What is main engine rpm?

Main Engine can run at 98 and 97 RPM if load is 55 and above. Main Engine can be run continuously at or below 86 RPM with Auxiliary Blowers and two Generators running. Main Engine cannot be run between 86 to 98 RPM corresponding to a load index of 43 to 55.

What is bhp in vessel?

BHP: Break Horse Power. The amount of engine horsepower. Bow thrusters: Propeller in the front of the ship enabling it to turn sideways without forward momentum.

What is the maximum rating?

Maximum ratings are the extreme limits to which the chip can be exposed for a limited amount of time without permanently damaging it. Exposure to absolute maximum ratings for prolonged periods of time may affect the reliability of the device.

What is a continuous load of a motor?

A continuous duty motor is treated as a continuous load, a load where the maximum current is expected to continue for three hours or more. Continuous loads have a multiplier of 125% applied when sizing branch circuits and overcurrent protection.

What is the difference between rated power and maximum power?

Peak power tells you about the voltage rails you’ll need to build and use. Rated power tells you about the average dissipation capability, without causing adversity.
