Mixer on my Sunbeam Model MX5900 compact mixmaster has burned out because beaters kept jambing in each other. Can I purchase just the mixer and beaters? Stand and bowl are OK

Where can I get brushes for a mmb mixmaster mixer

If the motors had burnt out then the winding can be redone if you can get this job to a winding shop.
Other wise the motor and assmebly can be ordered from a Sunbeam service outlet. try and see if you re able to source a motor assembly from a damaged/scrapped set with a mechanical defect.
