3 mar 2021 · First, consider that 1 HP = 745.7W. If your alternator demand is for example, 2kW, then you need 2.7 HP from the motor to drive it. The details of RPM and torque vs. power you'd have to get from the alternator supplier. Typical alternators were 50-70A at 12V, or about 720W (roughly 1HP.)
The following chart describes alternator output based on two temperature levels (ambient (26 o C) and hot (60 o C)). Test voltages are set at 13.5V (for 12V units). Engine-to-alternator drive ratios vary by engine, but a conversion factor of 2 is shown here for simplicity. Engine RPM. 500.
The alternator speed drops because the current is limited to 100 Amps. Next, the 2.8 HP load is abruptly removed, and the speed increases from 2800 RPM to 5200 RPM. This sequence is repeated one more time. This page contains alternator technical information for alternators converted to motors.
25 maj 2013 · Yes, an alternator can produce too much torque if it is over-tightened or if the engine is running at a very high RPM. This can cause damage to the alternator's components and potentially lead to failure.
Power is quantified in watts (J/s) or horse power. Note that the driving force of an electric motor is torque - not horsepower. The torque is the twisting force that makes the motor running and the torque is active from 0% to 100% operating speed.
The Cat ? C4.4 Industrial Power Unit is offered in ratings ranging from 61-81 bkW (81.8-108.6 bhp) @ 2200 rpm. These ratings meet U.S. EPA Tier 3 equivalent, EU Stage IIIA equivalent emission standards.
