Hello.
I want to run a universal motor with a battery.
First of all I made some experiments and by adding a full bridge rectifier on 220v ac i could successfully run the motor in approximately 200v DC and I did this because with DC I can control the voltage to the motor more easily. So this is a success and i tested it.
Now I want this idea to be portable.
I took a 12-volt car battery and I connected it to a (250W) small inverter then I connected the output with a full bridge rectifier and I could run the motor in DC. Because the motor is 400 watt I can't just connect the inverter to the motor directly but if I put the full bridge rectifier for some reason the motor works but with only one issue. If I put my hand to the motor I could stop the motor with ease. My question is if I can some way increase the current going to the motor and have more torque. The voltage going to the motor is adjusted from 25 to 200 volt. But i think the current is too low and that's why the motor doesn't have torque.
Is there a way to increase the current ? The full bridge rectifier can handle 35Amps and i want approximately 10 to 12 amps
Thanks in advance
