When driving two DC motors wired in parallel, do they each require their own flyback diode or can they share a single diode?

    \$\begingroup\$ One is ok. Since they are parallel, the the diode will catch any spike thru it. \$\endgroup\$ – Bianca Nov 12 '16 at 8:18

    \$\begingroup\$ Depends on the distance. If motor A is close to your driver but motor B is far away and only B has a diode, you can still fry your driver. \$\endgroup\$ – winny Nov 12 '16 at 8:25
  • \$\begingroup\$ Motor A & Motor B would be not more than 3cm (~1 inch) from each other and sharing the same conductor to the driver. Main reason I ask is virtually every circuit or diagram I can find has a flyback per motor (though admittedly not usually wired in parallel) \$\endgroup\$ – Peter Nov 12 '16 at 12:34
