WebFeb 15, 2010 · Electric motor research. Feb 12, 2010. #2. The brake resistor doesn't slow the load. Instead what happens is that the VFD causes the motor itself to operate as a generator. The motor becomes a mechanical load, turning kinetic energy stored in the inertia of the system into electrical energy.
