Fundamental in the design of a H bridge that drives a dc motor is a bulk storage capacitor across the H bridge supply. This capacitor "soaks" up the leftover energy in the motor that will force itself onto the power rail. 99%
How to eliminate the DC motor back emf? | Electronics Forums
The motor is a very high power DC motor, so it has high inductance. I am using a relay to switch on motor. And for the input signal of the motor, I use a triac to chop in different angle to control the speed. Because the chopped signal is in AC, then i rectify it by a bridge and use a filter capacitor to smooth it.

How to connect a capacitor to a motor?
The bank of capacitors should be connected directly to the terminals of the motor. It is recommended that special motors (stepping, plugging, inching, reversing motors, etc.) should not be compensated.
Should I put a capacitor across the motor terminals?
You should always put a capacitor across the motor terminals even if your circuit is not affected, because brush arcing creates rf noise that can interfere with other equipment (eg. AM radios). The usual recommendation is to install two 0.1uF ceramic capacitors, one connected from each motor terminal to the case.
