Salton VitaPro Brushless Fan Upgrade

This upgrade replaces the shaded pole motor and fan for the blower in the dehydrator with a brushless DC motor. A plate to mount the power supply and control potentiometer are provided as well. FWIW this unit makes an excellent filament dehydrator when paired with these extension units by steriku . The FreeCAD files are include if you want to change things up. You will need to tie into the 120V line on the dehydrator. DO NOT ATTEMPT THIS WORK IF YOU ARE NOT COMFORTABLE WORKING WITH ELECTRICITY. I AM NOT LIABLE FOR ANY DAMAGES OR INJURY AS A RESULT OF THE FOLLOWING INSTRUCTIONS It requires A 24V power supply. I used a 85-265V board rated for 2A. Board has a model of DTS36-ES, but that part number doesn't work on most of the usual sites. The power supply measures 9.0cm by 4.9cm. An A2208 1100kV style brushless motor. Note that just getting this motor rotating produces enough airflow to limit the output temperature of the heating coil to 65C at full power (Does anyone know of a more powerful heating element that can be easily installed in this unit?). A slower motor would be better but I cannot find one at less than 1100kV. A Gaqqee 200W 24V BLDC motor driver with potentiometer speed controller. Note that this driver can easily pull more than 48W, so it will cause the power supply to do into shutdown if you run it too fast. Other motor drivers are likely fine as well. An M5 nut to press into the back of the fan. An M3x10ish socket head cap-screw. To install: print the fan and the three brackets. Install the M5 nut into the fan, Install the motor to the fan bracket. Remove the metal baseplate from the dehydrator. Remove the shaded pole motor from the metal baseplate and salvage the 4 fasteners securing the motor to the bracket on underside. and attach the fan bracket to the baseplate using the mounting screws salvaged from the old shaded pole motor. Screw the fan onto the motor shaft using the M5 collet included with the motor Reinstall the baseplate with the new motor back into the dehydrator Wire the motor to the BLDC motor driver. I recommend soldering and heat shrink tubing. Secure the power supply to the base of the dehydrator using the power supply bracket. Affix ferrels to the BLDC motor supply and wire it to the output terminal blocks on the power supply. Wire the power supply to the 120VAC supply in the dehydrator housing. Move the Salton sticker on the front to the left (past the raised edge on the front of the unit) and drill a 1/4" hole for the potentiometer to go through. Using the potentiometer bracket as a guide, drill a 1/8" hole to allow for the M3 socket head cap-screw to pass through. Install the potentiometer using the bracket. Test and reassemble!
