Aussie Home Brewer Milling Motor COMBO Deal!
12V-48V 40A Bi-Directional DC PCB Speed Control Module + Worm Drive Motor 200W, 180 RPM, 20Nm Torque!
All you will need to source is a Switch Mode Power supply (around $33), a 12mm shaft that goes internally into the gearbox drive shaft and a coupling to go from the 12mm shaft to the shaft dimension of your mill.
A suitable power supply would be a 12V 20A Switch mode Power supply. one we have personally tested is eBay item number 400469998223 for $25.99 AUD with Free Delivery. It is a very good supply. If you want a little something extra up your sleeve, then there is also a 30A 12V available for only $33.99, also with free shipping. Both great value.
This heavy duty Worm Drive motor and gearbox is capable of moving up to 20Nm of torque at speeds between 160-180 RPM to your mill. The worm drive gearbox itself is extremely tough and can actually handle forces greater than 30Nm for short periods!
The motor package is extremely durable. To give you an example, we had one customer who bought one of the very first units we offered up for sale 5 years ago. They used the motor for 2 years daily while they prepared to open their brewing shop. When they opened the shop, they had the motor running SOLID every day for 3 years. We sourced this unit, because not only is it extremely fast for a worm drive, it also packs a punch in the torque range too. Its a best of both worlds type motor, combining both speed and power. You can mount a load to either side of the worm drive gearbox, though it can only be fixed from one side.
No Load Current: 1.8 Amps
Working Voltage: 12-16V Volts DC
Peak Torque: 20 nM (Newton Meters)
Motor Speed: 3600 RPM/160-180 RPM at Gearbox
Rated Current: 16-20A
Please note! The shaft inside the motor can accept a 12mm shaft! Any bigger and it wont fit, the diameter of the hole is 12.1mm!
40A 12V-48V BI-DIRECTIONAL CONTROLLER:
In absense of our own in house bi-directional controller, we've brought in a relatively basic but very reliable bi-directional controller!
The functionallity is insanely simple. The connected rocker switch is a 3 position switch which offers forward/reverse, and a middle neutral option. The on/off function is built right into the 100K pot, simply turn it down all the way until you hear a satisfying click and the unit is now off! The unit features soft-start (when using the pot from an OFF position).
We have found through rigorous testing that the difference in speed between positions l and ll is upto 5%
The most unique feature of this controller is a digital display, which displays between 001-100. Though its a good indication of how fast the motor is rotating, the readout is simply feedback from the 100k pot (i.e. A value of 50 on the LED readout indicates the controller is set to 50% of the motors maximum rated speed).
Setting the unit up is as simple as connecting 4 wires!
The battery positive/negative MUST be in the correct position when the unit is connected to power (please see gallery for indications as to which is which).
The motor positive/negative may each be on either of the motor terminals.
