12v DC motor precise stopping point?

AI Thread Summary
To control a 12v DC motor for a motorcycle kickstand, install normally-closed microswitches on the frame to manage the motor's extension and retraction. These switches will automatically shut off the motor when the kickstand is fully extended or retracted. The extension circuit is activated when the kickstand goes down, while the retraction circuit is activated when it swings back up. This setup ensures precise stopping points for the kickstand's movement. Implementing this solution provides reliable operation without manual intervention.

Lets say I want to move a kick stand on a motorcycle by use of a motor. Hooked up to the battery and a button on the handle bar. Is there a way of controlling the motor so it will automatically shut off when the kick stand has swung down all the way? Also when it has swung back up?
Thanks, Hoovy

Welcome to PF, Hoovy.
It's really simple. Just mount a couple of normally-closed microswitches on the frame, wired into both the extension and retraction circuits. When the stand goes down, it trips the switch wired into the extension lead. That still leaves the other side active. When it goes up, it trips the retraction shut-off.
 
Ahhh I see said the blind man. Thanks Danger
 
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
