RE: [PSUBS-MAILIST] Battery Switches



Doug,

 

We found some 200 Amp hand operated switches on the Halfmachine  Maybe you also can recycle them from a scrapped industrial application as the will be very expensive new.

A Euronaut team member has build a small , water-cooled electronic controller. Has not operated yet.

 

Yes, old style without much losses is having 4 speeds by 2 banks of batteries and 2 engines.

 

Groet, Emile

What switches are available for changing how lots of batteries are combined in order to change the voltage to a motor?  There has got to be something simpler that an bunch of 200 amp latching relays. 

When I toured the WWII subs I remember a bank of large handles.  Were they recombining the batteries to control the motors speed?

I am trying to avoid a big expensive PWM and any power losses associated with it. 

How is Euronaut controlling motor speed?

Thanks
Doug J
