What is a "DC reactor"? Is it a DC power supply, DC wall wart or battery?
What is a "braking resistor"?

dc Reactor is filter in inverter and braking resistor is to braking a motor by inverter

The DC brushless motors on my model airplanes are programmed to be braked at minimum speed by the Mosfets in the Electronic Speed Controller.
They do not use an inverter but Pulse Width Modulation is used for speed control without using a filter.

Interesting indeed!
A motor can be braked by simply shorting the terminals. But for large motors all the rotational energy is dissipated in the windings as heat and it can be substantial (the motor can be damaged permanently). Hence for large motors brake can be applied via an external high wattage low value resistor.
For energy conscious designs, the motor can be braked by an charging circuit (regenerative braking) in which the energy is not dissipated but recovered and can be used later.
Motor can be braked by an inverter as such.
