Default Re: Wiring Question - Why Does the Solenoid Click on Accelerate and Not on Key Switch

That way if the controller fails and the cart starts to run away, lifting your foot will open the solenoid and stop it. (but not all carts are wired this way) My Yamaha isn't. The controller doesn't open the solenoid until a few seconds after taking the foot off the gas and coming to a stop based on the speed sensor. Turning the key off does open the contactor but in "Panic Mode" if the cart goes to full power, it takes a bit to get to the key to turn it off!

That's a use that's peculiar to golf carts/EVs then. In industry contactors are normally used to start/stop motors. How else are you going to automatically start/stop a 3-phase 480V 50HP motor?

That's correct. All EV's have a "safety contactor". Industrial motor contactors are often used to start/stop large motors - without a speed controller. Just on or off. Those contactors are designed to handle the high starting currents that big motors require.

You can stop an AC motor quickly by applying a DC voltage.
