Dear all
In order to run 48V, 0.6A motor with 24V power supply, I implemented circuit bellow which used charge pump and generated negative voltage. the voltage around the motor is near to 48V and motor works properly; but the problem is that both of 1N4007 diodes become too hot. is it the nature of these diodes to become hot at this current?

Thanks for any helps..
