  • CR4 - Thread: Reversing DC Starter Motors
    Here is a 12 volt reversible motor from an electric winch.
  • CR4 - Thread: Omni Directional TV Antenna
    It runs from DC to ground to power the amplifier with 12 volts or so and it has a reversible motor drive to turn a small yagi inside the dome.
  • CR4 - Thread: Changing the Direction of Movement for a 12 VDC Motor
    That way, when we cut the + 12 volts to the motors , we slapped -1.5 volts across it instantly putting it into reverse .

    � Safa tempo); an advanced D.C. motor (K91-4003 6.7" motor) or Prestollite motor; a motor controller (Curtis 1209B); 72 volts of battery power ( 12 - Trojan 125 batteries); a � � parts such as a reverse -forward switch, motor mounting plates, couplings, a �
  • CR4 - Thread: Generator without fuel engine
    The idea is to find a gear box with non- reversing torque so that it is driven in one direction without excerting much torque on the prime mover which will be the 12 volts motor .
