i use a 1.5hp 24 volt motor on the deck of my MINI. the deck is 22" and it gets pretty warm after an hour of cutting.. i use a 500 watt motor for the drive system with a controller and it runs hot i run it 1 hour then give it a 10 minute cooling down period.. i put a blower on the drive motor. after the 10 minutes of cool i run it for another hour.. after that the batteries are reading 11.5 volts and i try not to go any lower then that..
Can you explain how the controller you are talking about works? The only motor control systems I am familiar with are stepper motor controls and variable frequency drives for three phase ac. Is this a current limiter like stepper controls? Thanks in advance for any info you can offer.
