Hi, I have a question about the use of a bridge rectifier. We have a vacuum that runs off of 120vac/60hHz power supply. The motor inside the vacuum is the motor seen here...

Also incorporated into the circuit(internal to vacuum) is a bridge rectifier. The one used can be seen here...

My question is what purpose does this rectifier serve? The motor is rated at 120vac/50-60Hz which it seems to me would be available from the power supply when it gets plugged in. Any clarification would be greatly appreciated. Thank you.
