How much horse power does a 1kW alternator need?

To figure the horse power it is 746 watts of power for 1 HP. that means you have to have 1.34 hp for each kw or kva. The stand rule is to us 1.5 hp per KW or KVA for effencey loses. Note that most electric motor run at lower or higher rpm’s that will change frequncy on you alternator out put. I…

What size alternator do I need for my Drive?

Generally speaking, you will need an alternator that is at least 5 x the peak requirement for the drive. This is not specific and in some cases the multiple can be as high as 7 x the drive size. This should be calculated as a multiple of the Input Current (not motor kW). The alternator should be capable of 5 to 7 x the drive Input KVA.

Can you run an alternator with an electric motor?

Yes you can run a Alternator with a electric motor. To figure the horse power it is 746 watts of power for 1 HP. that means you have to have 1.34 hp for each kw or kva. The stand rule is to us 1.5 hp per KW or KVA for effencey loses.

How do you calculate alternator capacity?

This should be calculated as a multiple of the Input Current (not motor kW). The alternator should be capable of 5 to 7 x the drive Input KVA. For a DC drive – Input Current is DC Current x 0.82 = AC Current for the armature.

Can I use an electric motor with a flywheel?

No, the only use a flywheel would have in conjunction with an electric motor is when an intermittent load requires more power than a motor can deliver on its own. Rock crushers, metal shears and punches and other equipment use stored flywheel energy to deliver many times the available horsepower of a drive motor for a short period of time.

Can I run a generator with a diesel engine?

Yes, it can be run. But you need a very big motor to run the generator and a very good speed controller to control the speed of your motor and of course, you will loosing power and wasted energy and electricity for nothing. At the end you may have to pay more than to run the generator with a diesel engine.
