Motor Circuit Switch

Most motors require more current and or voltage to operate.

Motor circuit switch.

A transistor can act as a digital switch enabling the arduino to control loads with higher electrical requirements. If we wanted to keep the motor running even after the operator takes his or her hand off the control switch es we could change the circuit in a couple of different ways. Help provide on off control of your motors with motor circuit breakers from grainger. Rated in horsepower and capable of interrupting the maximum operating overload current of a motor of the same rating at the rated voltage.

When used with properly sized branch circuit fuses pullout switches may be used for motor motor circuit and group motor protection. The contact in parallel with the run switch is often referred to as a seal in contact because it seals the momentary condition of the run switch closure after that switch is de actuated. The interlock contacts installed in the previous section s motor control circuit work fine but the motor will run only as long as each push button switch is held down. We could replace the push button switches with.

A switch intended for use in an electric motor branch circuit. Marked motor circuit pullout switch they may be used only in a motor circuit. This example uses a tip120 which can switch up to 60v at 5a. The transistor in this example completes the motor s circuit to ground.

This circuit is known as a latching circuit because it latches in the on state after a momentary action.
