Favorite Motor Relay Connection

If you move the switch the motor should spin in one direction until the related endstop is pressed.

Motor relay connection. The positive wire from the 9v battery will connect to both of the no top inputs. A relay mechanism basically consists of a coil and a spring loaded contact which is free to move across a pivoted axis. Once the endstop is pressed the motor goes again in a braking configuration and it will remain steady as long as the endstop is pressed or the switch isn t switched to the other side.

The coil terminals of the relay are connected to the supply with a push switch. Mechanical relays create a clicking sound that indicates movement o the common terminal. Each relay switch has three inputs no normally open com common and nc normally closed in this project both wires from the motor will connect to both of the com middle inputs of the relay switches.

Applying a magnetic field to the coil causes the reeds to act as an actuator and a contact blade while switching occurs. Any increase in ambient temperature from the limit causes the contacts of a thermal relay to switch from one position to another as it protects a motor or other device from an overload condition. When a relay is off the common is connected to the nc normally closed.

The no normally open connection of the relay is not connected until the relay turns on. Connection of the relay board and pin discription of two type of relay board and on off condition. The normally closed terminal of both relays is connected to negative or ground.

In dual spdt motor driver circuit the dc motor terminals are connected between the common poles of the two relays.
