i have fet3-dynamo circuit baord.

My motors are KL23HM276-30-8B Unipolar motors with 2.76V and 3.0Amp per phase. Currently i am using 5V power supply with 50watt 0.33ohm power resistors. With this voltage i am getting 12 IPM. My router is all steel 1000mm x1300mm x200mm and gantry wait is about 40Kg.

Currently I bought 24V 24Amp power supply. I want to use this but the power resistors alone cost $166 US.

Please tell me
a)can i use light bulbs in place of power resistors.?
b) what will be the wattage and configuaration of light bulbs?
c) what forseen IPM can i get?

Best regards
