is the actual horsepower output to the drive motor.
The actual horsepower of an engine, measured by a brake attached to the driving shaft and recorded by a dynamometer.
The measure of an engine's horsepower without the loss in power caused by the inefficiencies in the accessories and drivetrain.
Outmoded measure of the power developed by an engine, as recorded on a dynamometer and stated in brake horsepower, or bhp.
Brake horsepower (sometimes referred to as shaft horsepower) is always measured at the flywheel or crankshaft by a "brake" or absorbing unit. Gross brake horsepower describes the power output of an engine in stripped-down, "race-ready" trim. Net brake horsepower measures the power at the flywheel when the engine is tested with all standard accessories attached and functioning. Also see Horsepower, Indicated Horsepower, Friction Horsepower, and Torque.
The measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump and other auxiliaries. The actual horsepower delivered to the driving wheels is less.
Measurement of an engine's power as determined by a brake attached to the drive shaft and recorded on a dynamometer.
the power available at the shaft of an engine after minusing the frictional losses in the running component of the engine but before passing through reduction gears or other transmission devices; for direct-connected diesel engine, this power is same as shaft horsepower; this is measured using a brake which gives the name; bhp for short
Horsepower delivered to the output shaft of the drive motor. Unit of comparison between motors. Total package bhp is the sum of all motor shaft outputs, including compressor and cooling fans
(Abbreviated b.h.p.) The Horsepower available at the propeller shaft of an aero engine. It differs from the Indicated Horsepower by the power needed to overcome the internal friction of the engine. The term is derived from the convenient method of measuring the horsepower developed at the propeller shaft by running the engine against a calibrated brake.
The work done by an electric motor in driving the fan and measured as horsepower (hp) delivered to the fan shaft. In belt-drive units, the total work load is equal to the work load of the electric motor plus the drive losses from belts and pulleys. The brake horsepower is always a higher number than the air horsepower.
The power provided to the pump shaft, and consumed by a pump in order to move fluid at a desired flow rate and head. The ratio of fluid horsepower to brake horsepower is the pump's efficiency.
Horsepower delivered to the output shaft of a motor or engine, or the horsepower required at the compressor shaft to perform work.
Usable horsepower of an engine measured at the crankshaft.
Engine horsepower rating as determined by brake dynamometer testing. (see Horsepower)
The horsepower actually required to drive a fan. This includes the energy losses in the fan and can be determined only by actual test of the fan. (This does not include the drive losses between motor and fan).
1. The horsepower required at the top or end of a pump shaft (input to a pump).
The power delivered by a diesel engine before entering any reduction gear.
Actual horsepower developed by a motor, engine or other machine during operation, as measured by a Prony brake or similar device.
