I ordered a 36V 500W brushed DC motor but unfortunately a 24V one came. I'm faced with the dilemma of returning it and waiting for a month before getting a refund, then ordering a new one and waiting about a month again for it to arrive, totaling 3 months of waiting (with the current one), OR run it beyond its ratings.
I understand that increasing the voltage will increase the rotation speed proportionally. It is currently rated at 2700 rpm @ 24V and ~27A drawn. If I increase the voltage to 36V then rpm will rise to about 4000 and to maintain the 500W power output I will need to supply ~14A.
Questions that arise are:
- Are my assumptions correct in the first place?
- Is it possible for construction damage to occur when running a motor beyound its rated rotation speed?
- Is efficiency compromised in such setup.
