It's two sides of the same issue. Stalling motors uses a lot of power, and therefore creates a lot of heat. Fan/Air cooled motors (rs775/550, am9015) are more likely to burn up without the spinning fan, while high thermal mass motors like CIMs and mini CIMs will probably survive, but only after using large amounts of power. Holding large motors like CIMs and rs775s at stall (even with less than 12v being applied by the controller) will also lower the battery voltage available to other motors while it is holding the lift, in addition to draining the battery. All of this said, we don't plan on having a brake initially.
