Hi coone,i have an boat engine with a dyno start which mean it starts the engine, then when it it running it becomes the charger is there any motor out there which could do the same in regards to regen breaking ????
i'm just wondering if this is possible
All motors can generate and all generators can motor, if properly excited. Here, "excited" means the type of field winding in the dynamo (which is an electric machine (motor or generator)) and the controller between the dynamo and load and/or source. So, one dynamo can function both as a starter motor and generator for battery charging and auxiliary system power.
But in the real world, a starter motor needs high current for high torque to crank the engine and a generator runs at relatively low current for battery charging and headlamps and stuff. So using a single machine (dynamo) for both functions is a compromise. It can be done, obviously. But such are usually only used on smaller engines not requiring large cranking torque. And then the generator efficiency suffers. But the good news is that it cost less to attach a single dynamo to your engine than both a cranking motor and an alternator.
And yes, this "dynamo" can be made larger and designed differently so it starts the engine, can actually propel the vehicle to some degree and charge the battery, either from the engine power or from regeneration. See the Honda hybrid system for an example.
Pick one 144V A lot depends on the particulars. Hang around and read a lot and then ask some reasonable questions and you can figure it out. No one answer fits all.2nd question
whats a gd voltage and ampage to start at for a 100mile range car with a warp9 engine on a light weight sports car
ps...please call it a motor (or dynamo ), not an engine.
