1.1.14 Which brake rectifiers are used in the standard brake motor?

Brake rectifiers provide the DC voltage supply to electromagnetic brake coils that release, or more precisely, engage, the electromechanical brakes on electric motors. A standard brake motor incorporates a spring-applied brake, which is supplied with DC voltage via a 230V (bridge rectifier) ​​or 400V (half-wave rectifier) ​​rectifier.
