Variable Frequency Drive 1 ph to 3ph

I want to run a 3 phase motor on 1 phase 120 volts with a VFD. I see lots of VFD's that do this but not sure how a motor brake would work with this. The 3 phase 1/2hp motor has a C-face mounted Dodge D series brake(200-230v). Can this be done with a VFD and would the VFD run the brake or would it be wire to the motor directly (when the motor de-energizes from the VDF this would apply the brake?) Or can you recommend a VFD that controls this type or brake and a 3 ph motor.

Most motor brakes I have seen are derived from a half wave rectifier, which will turn the motor into a generator in reverse when the current is removed, slowing it to almost zero until the field is lost. Not sure how it would work on your application.
