    Leaf / leafmotor / leafbike high efficiency 1500w motor

    The Leaf motor I got in February of last year has a 10k thermistor under the coils. Works fine with the CAv3. Before I had the CAv3 I tried using a Taylor digital meat thermometer but the resistance of the Taylor thermistor was different and displayed the wrong temp. The Taylor thermometer...

    Assessing interest in MXUS 205/35H V2

    The XF40-35H and the popular XF40-45H appear to be assembled in the same outer shell. I don't think Mxus sells a motor with magnet back steel in 40mm width like the leaf 1500w. This might be why they were reluctant to sell a 35mm width stator. If this is the case you might as well just get the...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I have only used the 5t motor. I recently put my 5t in a 19" motorcycle wheel and the torque is great. Over all diameter of the 19"x2.25" vee rubber vrm 013 tire is 23.5" On 18s 45a it will do 41 mph on the flats and pull 32 mph up a 5% grade. With the 26" big apple tire, 27" OD, the top...

    The wire bundle on the leaf 1500w doesn't come out the end of the axle. It comes out at an angle from the side of the axle between the dropouts. I have my torque arm on this side because the slot leaves less material in contact with the dropout flats. Merry Christmas Patrick

    LightningRods mid drive kit

    @ John Bozi You're jackshaft being bent might be the cause of your oscillations. My grub screw fell out of the 12t driver on the secondary side and got wedged between the chain wheel and chain. I don't have the secondary tensioner yet so it bent my jackshaft. Bent so bad in fact that when I...

    19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

    The VRM 021 does look like a great tire for dual purpose use. I went for a light combo with the least amount of OD for a 19". The VRM 013 2.25 is super smooth and still has enough side wall to give a good ride even on a hardtail. My Santa Cruz with a LR small block is my off road bike but...

    LightningRods mid drive kit

    @ Dingus Your gonna have to wait in line bro. Like Mike said before he is only one man. This kit is definitely worth the wait. Give him some more time and be patient. Mike is a stand up guy and will take care of you to the best of his ability. No need for a paypal dispute.

    19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

    Thanks Baron I have a 5t leaf 1500w so the kV is 10.1. Top speed in a 26" wheel was 52 mph at 120% throttle. I should be able to hit 45 mph with the 23.5" OD tire. This motor has a flange diameter of 232mm and flange spacing of 40mm. The overall diameter is 243mm. 128mm spokes were a good...

    19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

    Laced up and tire mounted. The 19"x1.4" MC wheel was easier to lace and true. I had to improvise and used a giant spoon to get the bead of the tire over the rim. Don't tell the wife :twisted:. The 26" bike wheel assembly weighed around 20lbs. The 19" wheel weighed around 27lbs. Not to bad.

    19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

    The nipple diameter is 5mm so the spoke holes are less in stock form. Resized the spoke holes already. They came out great. here are some links. http://www.treatland.tv/semi-gloss-satin-black-NINETEEN-inch-rim-p/black-nineteen-inch-rim.htm...

    19" Motorcycle Wheels vs 26" Bicycle Wheels (rim and tires)

    I'm taking my 1500w leaf motor out of it's 26" bike wheel and lacing it into a 19" MC wheel. Tired of the flat tires and short tread life. Looking to improve torque with the added benefit of reducing the load on the motor resulting in lower temperatures and improved efficiency. I picked up a...

    Hallomotor hubs on ebay, August 2015

    I wonder if this motor is the same as the leaf 1500w. Hey SamRich can you open your motor and measure the thickness of the stator laminations? I hope they are 0.35mm like the leaf. I wish hallo motor would put up a dyno graph or at least give us an efficiency number. I also saw this motor...

    SLCD-3 display settings, P and C parameters

    C13 adjust the level of regenerative braking from 0-5. C14 is for pedal assist power tuning 1-3 weak assist to strong assist. Does anyone know how to wire the temp sensor in the motor to the display? I turned C8 to 1 which enables the motor temp reading. The display shows 32f on the screen so...

    Their rims a crap. At least you got to ride yours. My clients wheel was bent and cracked right out of the box. It was under the foam portion so somebody dropped it and thought the foam protected it. That was 4 months ago and still no reconciliation. Buy only the motor. The rest of the kit...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    My thermistor wire is purple. Its between the pos and neg wires in the hall connector. I run a CA3-DPS so I repurposed the yellow wire on pin 5 of the CA connector to carry the temp signal. The CA3-DPS has an external speed sensor run off my front wheel so I don't need the yellow wire for...

    To get regen to work you connect the two white wires together on the infineon/Em3ev type controllers. If you want regen to activate while pulling the brake lever you must wire your brake switch directly to the controller. You also want to wire your brake switch to your CAv3 so it knows when to...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I thought the resistance was too low to measure with a DMM. You must load the circuit and measure the voltage drop across the phases. Gotcha. This may take some time to rig up since I'm deep in my LR mid drive project at the moment.

    Measurements this morning Phase to Phase Resistance at 21.8c A to B = .2 ohms A to C = .2 ohms B to C = .2 ohms 13*5t No Load Rpm at 48v = 485 Rpm Shoulder to Shoulder Width Freewheel Axle = 134.4 mm Looking at pictures I don't see one large gap between the magnets

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I vented and added a centrifugal fan on my hub motor last weekend. It helped the motor heat up slower and cool off quicker. Even vented though this motor still gets hot on the hills. 18s using 2500w on the flats I can do 40 mph and the temp stays between 100c-110c. After the motor is warm...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    The Leaf controller is limiting. You can't adjust battery current, phase current or any other parameters at the controller itself. The only adjustment you do have is the 0-5 levels of assist on the display that comes with the kit. You do get a little more acceleration from level 1 to level 5...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    If your not going to run 18s or higher I would go with the 12 fet 3077 for efficiency. Before I fryed my leaf bike controller I was using less watt hours than with my 12 fet 4110 with the same 48v 15ah Calibike battery. Not sure what 12 fets are in the leaf controller but they don't like...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I do have lots of hills to contended with much like your terrain Nep. To get the temp to 150oC I had to ride up and down my street a dozen times using a lot of regen at the bottom. Not sure of the grade in front of my house but pedaling up it is a chore. I will set the CA for a max of 130oC...
