Wheelchair motor break question

<< < (2/2)

jwatte:
That looks fine to me, assuming the controller and brakes are rated for 24V. The brakes may be implemented as some kind of coil with a spring; if that's the case, you may want to add a kickback reduction diode across the brakes, and perhaps a capacitor. Else, when you cut power, the kickback from the coil may give enough voltage as a short spike on the electrical line to damage your controller. You can probably measure this with a good oscilloscope if you worry about it.
