For those that don't know, the hubmonster is a 6 phase hub motor. They are no longer made, but if you ever run across one, buy it! They are simply the best of the best hub motors.
There's 3 versions:
1. Mini hubmonster: It is a top of the line 3 phase hub motor. I have one and I know that it's far better than any other hub motor I have ever seen. They can do around 6kw
2. Midi hubmonster: This is a top of the line 6 phase hub motor. I've never seen one of these, only heard about them.
3. Hubmonster: I have 2 of these and you will see one taken apart below. They are possibly the best ever hub motor and have 6 phases. It's not uncommon for people to run them at 30kw or more. They run really well above 100v.
I've looked around and not seen anyone take apart a hub monster before. This motor has been recovered from a partly wrecked Zapino Zap electric moped that ran at 60v and used dual 12 fet controllers to run the motor. They rated the motor at 6kw which is laughably LOW. Last night, I finally got around to taking the moped apart and scavenging the good bits. I bought it for the motor. It's been sitting in the weather for quite a while so the entire moped was pretty badly oxidized and covered in dirt. This motor will be the power plant for my next build. I'm terrible at guessing weight, but I'd say 40 pounds or so.
This is after I removed it from the rim and cleaned up most of the grunge that was on it. Several of those 8 screws had the heads wallowed out. I don't know when it happened, but 3 of them were so nearly gone that I barely got them loose!
Since these motors are 6 phase, you have 6 wires to connect to 2 controllers, 2 sets of halls and a temp sensor. The phase wires are white teflon coated 10 awg. Each phase wire is then covered in colored heat shrink.
I've removed the 8 screws and am using large headed screws to lift off the armature. Without a 3 jaw puller, just don't EVER do this. The magnets are quite large and if you can't control the removal of the armature, you won't succeed!
The magnets in the armature are massive and quite strong. I bet they are N40 or N45. There's 20 of them.
The shaft bearings are 5205DU. Despite this scooter sitting in the weather for many years, these bearings are really smooth and perfect.
The motor has 6 halls in it. What you are seeing is 2 halls from 2 separate sets of motor phases.
The 6 halls definitely looks interesting.
This stator is just a beast. It's 7" across and 2 3/8" tall.
This is a bit disappointing. There's something like 30 strands of wire per phase that are about 30% larger diameter than the 10 awg wire that exits the motor. The red wire is length of 10 awg for comparison. No size difference! I have 8 awg teflon wire in a few colors. I wonder if I can cram 6 of them inside this axle? There's room around the six 10 awg wires and their extra layer of heat shrink. I bet 8 awg with no heat shrink around each wire would fit inside the axle.
I was curious to find out how the motor phases were terminated. This is the 2 sets of WYE connections.
It looks a good bit better now all cleaned up. I've replaced the 8 screws with new ones after tapping out their threaded holes to clean up any rust that might be in them.
